Creation of an event : problem with the container
Hi Gurus,
I'm facing a problem in creation of an event.
I'm in SAP ECC 6.0 for a migration project from 4.6B
In an ABAP program I'm trying to create an event in order to launch a workflow.
1st step : Set datas in the container -> In INTERNAL_TABLE I have 5 lines.
swc_set_table event_container 'INTERNAL_TABLE' t_cnp_container.
2nd step : Create an event :
CALL FUNCTION 'SWE_EVENT_CREATE'
EXPORTING
objtype = w_wf_objtype
objkey = w_wf_objkey
event = w_wf_event
creator = applicant
start_recfb_synchron = 'X'
TABLES
event_container = event_container
EXCEPTIONS
objtype_not_found = 1
OTHERS = 2.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
WRITE sy-subrc.
ENDIF.
Now when I check my container with SWI2_FREQ I see that INTERNAL_TABLE has just one ligne, the rest disapears.
I have this problem only when I set an internal table in an container
I don't know why, but it perfectly works on 4.6B.
Thanks a lot

Hi,
I dont see a point in having this statement
swc_set_table event_container 'INTERNAL_TABLE' t_cnp_container. Infact it is not needed !!
SWE_EVENT_CREATE like any other FM, take a
lt_var type standard table of SWCONT.
ls_var type SWCONT.
fill your ls_var with all fields and append it to lt_var each time and pass lt_var to event_table of SWE_EVENT_CREATE. It should work !!
However, suggested way is to use SAP_WAPI_CREATE_EVENT instead of SWE_EVENT_CREATE from ECC 5.0 onwards. There are fe concerns with SWE_EVENT_CREATE mainly with respect to commit and persistancy. Better we should use SAP_WAPI* as much as possible from ECC 5.0.
Try above and Good Luck !!

Hi,
One of my user is facing issue in creating new time sheet,
"The time sheet creation failed, because of problems with the project server or with data validations".
This issue is coming to only few members out of 10000 members.
Note: For the same user, can able to do in other machines. only the problem in his machine. Have ran the office diagnostics, but still the problem persists.
Is any add-on's/any settings need to update in IE. Could any one please help me on how to fix this issue?
Many thanks in advance.I would check the compatibility settings in IE etc, or try another browser (chrome, safari etc.)

Facing problem with the code for sending an .xls attachment via email, a field value contains leading zeros but excel automatically removes these from display i.e. (00444 with be displayed as 444).kindly guide .
Hi Chhayank,
the problem is not the exported xls. If you have a look inside with Notepad or something like that, you will see that your leading zeros are exported correct.Excel-settings occurs this problem, it is all about how to open the document. If you use the import-assistant you will have no problems because there are options available how to handle the different columns.
Another solution might be to get familiar with ABAP2XLS-Project. I got in my mind, that there is a method implemented, that will help you solving this problem. But that is not a five minute job

I keep getting a message about a problem with the plug in container for firefox. what does it mean?
I am getting a pop up box saying that there is a problem with the plug in container for firefox. It keeps saying do I want windows to find a fix for it and close it or do I just want to close the program. What is this plug in container for firefox and why am I constantly getting this message? It has been happening for the past month or two.
It means either you have a faulty/out of date plugin, or your firewall/antivirus is causing problems with Firefox.
Make sure you update all your plugins and disable unwanted ones.
https://www.mozilla.org/en-US/plugincheck/
https://support.mozilla.org/en-US/kb/disable-or-remove-add-ons
Also, make sure your firewall/antivirus is not blocking plugincontainer.exe from the Firefox folder in your computer. How you make sure that's not the case will depend on your firewall/antivirus. -

Problem with the creation of the _pageflow folder in the portal project
Hi,
I have developed one portal project on the BEA Weblogic Portal server version 9.2. And I am having a quite a number of pageflow portlets in my application.I am facing a weird problem with the workshop(BEA Workshop for Weblogic Platform 9.2.1). It is not generating the folder _pageflow required for all the protlets when we build it.I tried cleaning and building it number of times but it is of no use.
Is it a bug in the weblogic server version or do I really miss something in the workshop settings?
Please help.
Thanks & Regards
Prakash.Hi Dmitry,
What state are the tasks in? Are they in Active, Running, or Completed? There will only be output files if the tasks are in state running or completed.
Additionally, what is the status of the pool which the tasks ran on? If the pool VMs have been deallocated (or the pool itself has been deleted) then the task files will be lost. This is because the files of the tasks reside on the VM which ran
the task.
Lastly, you can check the file retention time of the tasks in the BatchExplorer UI by selecting the task and looking in the "Task Details" tab for "TaskConstriants.RetentionTime" to see what that is set to - if the retention time has
passed (i.e. retention time was 1h but the task was run 2h ago), then the files will be cleaned up.
It sounds like you already are using BatchExplorer, but we recently published a blog post which has some specific instructions for using BatchExplorer to debug (how to RDP into a VM for example), which you can find
here - it also has some code snippets for how BatchExplorer performs the operations that it does.
Let us know what you find from your investigation and we can help you figure out why your tasks don't have output files. -

Problem with the cache hit ratio
Hello,
I ma having a problem with the cache hit ratio I am geting. I am sure, 100% sure, that something has got to be wrong with the cache hit ratio I am fetching!
1) I will post the code that I am using to retrieve the cache hit ratio. I've seen about a thousand different equations, all equivalent in the end.
In oracle cache hit ratio seems to be:
cache hits / cache lookups,
where cache hits <=> logica IO - physical reads
cache lookups <=> logical IO
Now some people use the session logical Reads stat, from teh view v$sysstat; others use db block gets + db consistent gets; whatever. At the end of the day its all the same, and this is what i Use:
SELECT (P1.value + P2.value - P3.value) AS CACHE_HITS, (P1.value + P2.value) AS CACHE_LOOKUPS, P4.value AS MAX_BUFFS_SIZEB
FROM v$sysstat P1, v$sysstat P2, v$sysstat P3, V$PARAMETER P4
WHERE
P1.name = 'db block gets' AND
P2.name = 'consistent gets' AND
P3.name = 'physical reads' AND
P4.name = 'sga_max_size'
2) The problem:
The cache hit ratio I am retrieving cannot be correct. In this case i was benchamarking a HUGELY inneficient query, consisting of the Union of 5 Projections over the same source table, and Oracle is configured with a relatively small SGA of 300 MB. They query plan is awful, the database will read the source database table 5 times.
And I can see in the physical data statistics of the source tablespace, that total Bytes read is aproximatly 5 times the size of the text file that I used to bulk load data into the databse.
Some of the relevant stats, wait events:
db file scattered read 1129,93 seconds
Elapsed time: 1311,9 seconds
CPU time: 179,84
SGA max Size: 314572800 Bytes
And total bytes read: 77771964416 B (aproximatly 72 Gga bytes)
the source txt loaded to the database was aprox 16 G
Number of reads was like 4.5 times the source datafile.
I would say this, given the difference between CPU time and Elapsed Time, it is clear that the query spent almost all of its time doin DB file scattered reads. How is it possible that i get the following cache hit ratio:
Cache hit Ratio: 0,92
Cache hits: 109680186
Cache lookups: 119173819
I mean only 8% of that Logical I/O corresponded to physical I/O? It is just not possible.
3) Procedure of taking stats:
Now to retrieve these stats I snapshot the system 2 times. One before the query, one after the query.
But: this is not done in a single session. In total 3 sessions are created. One session two retrieve the stats before the query, one session to run the query, a last session to snapshot after the query.
Could the problem, assuming there is one, be related to this:
"The V$SESSTAT view contains statistics on a per-session basis and is only valid for the session currently connected. When a session disconnects all statistics for the session are updated in V$SYSSTAT. The values for the statistics are cleared until the next session uses them."
What does this paragraph mean. Does it mean that the v$sysstat only shows you the stats of the last session that closed? Or does it mean thtat v$sysstat is increamented with the statistics of each v$sessionstat once a session terminates? If so, then my procedure for gathering those stats should be correct.
Can anyone help me sort out the origin of such a high cache hit ratio, with so much I/O being done?sono99 wrote:
Hi,s
first of, let me start by saying that there were many things in your post that you mentioned that I could no understand. 1. Because i am not an Oracle Expert, i use whatever RDBMS whenever i need to. 2. Because another problem has come up and, right now, i cannot inform myself to be able to comprehend it all.Well, could it be that you need to understand the database you are working on in order to comprehend it? That is why we strongly advise you to read the concepts manual first, you need to understand the architecture that Oracle uses, as well as the basic concepts of how oracle does locking and maintains read consistency. It does these different than other database engines, and some things become nonsense if looked at from the viewpoint of a single user.

quote:
It would be useful to see the execution plan jhust in case you have simplified the problem so much that a critical detail is missing.
First, the query code:
2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:>SQL> CREATE TABLE FAVFRIEND
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 2 NOLOGGING TABLESPACE TARGET
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 3 AS
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 4 SELECT ID as USRID, FAVF1 as FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 5 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 6 SELECT ID as USRID, FAVF2 AS FAVF FROM PROFILE
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 7 UNION ALL
[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 8 SELECT ID as USRID, FAVF3 AS FAVF FROM PROFILE

[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 13 ;
Now, Althought it is clear from the query that the statement is executed with the NOLOGGiNG, i have disabled the logging entirely for the tablespace.There are certain rules about nologging that may not be obvious. Again, this derives from the basic Oracle architecture, and if you use the wrong definitions of things like logging, you will be led down the primrose path to confusion.
>
Futhermore, yes, the RDBMS is a test RDBMS... I have droped the database a few times... And I am constantly deleting an re-inserting data into the source database table named PROFILE.>
I also make sure do check all the datafile statistics, and for this query the amount of RedoLog, Undo "Log", Templife used is negligible, practically zero.Create table is DDL, which has implied commits before and afterwards. There is a lot going on, some of it dependent on the volume of data returned. The Oracle database writer writes things out when it feels like it, there are situations where it might just leave it in memory for a while. With nologging, Oracle may not care that you can't perform recovery if it is interrupted. So you might want to look into statspack or EM to tell you what is going on, the datafile statistics may not be all that informative for this case.
>
Most of the I/O is reading, a few of the I/O is writing.
My idea is not to optimize this query, it is to understand how it performs. Well, have you read the Concepts manual?
I have other implementations to test, namely I having trouble with one of them.
Furthermore, I doubt the query Plan Oracle is using actually involves tablescans (as I I'd like it to do); because in the Wait Events, most of the wait time for this query is spent doing "db file scattered read". And I think this is different from a tablescan.Please look up the definition of [db file scattered read|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/instance_tune.htm#sthref703].
>
Do you really have to use sessions external to the query session ? Can you query v$mystat joined to v$statname from the session itself.
No, I don't want to that!
I avoid as much as possible having the code I execute being implemented in java. Why do you think java has anything to do with this? In your session, desc v$mystat and v$statname, these are views you can look at.
When i can avoid it I don't query the database directly through JDBC, i use the RDBMS command line client, which is supposed to be very robust. Er, is that sqlplus?
So yes, I only connect to the database with JDBC... in very last session.
Of course, I Could Have put both the gather stats before query and gathers stats after query a single script: the script that would be also runing the query.
But that would cause me a number of problems, namely some of the SQL i build has to be implemented dynamically. And I don't want to be replicating the snapshoting code into every query script I make. This way I have one sql with the snapshoting scripts; and multiple scripts for running each query. I avoid code replication in this manner.Instrumentation is a large subject; dynamic sql generation is something to be avoided if possible. Remember, Oracle is written with the idea that many people are going to be sharing code and the database, so it is optimized in that way. For SQL parsing in particular, if every SQL is different, you get a performance problem called "hard parsing." You can (and generally should, and sometimes can't avoid) use bind variables so that Oracle doesn't need to hard parse every SQL. In fact, this is one of those things that applies to other engines besides Oracle. I would recommend you read Tom Kyte's books, he explains what is going on in detail, including in some places the non-Oracle viewpoint.
>
Furthermore, Since the database is not a production database, it is there so I can do my tests. I don't have to be concerned with what other sessions may be doing to my system. There are only the sessions I control.No, there are sessions Oracle controls. If you are on unix, you can easily see this, but there are ways to see it on Windows, too. In some cases, your own sessions can affect themselves.
>
then what it the array fetch size ? If the array fetch size is large enough the number of block visits would be similar to the number of physical block reads.
I don't know what the arraysize you mention is. i have not touched that parameter. So whatever it is, it's the default.You should find out! You can go to http://tahiti.oracle.com and type array fetch size into the search box. You can also go to http://asktom.oracle.com and do the same thing, with some more interesting detail.
>
By the way, I don't get the query results into my client, the query results are dumped into a target output table.
So, if the arraysize has something to do with the number of rows that Oracle is returning the client in each step... I think it doesn't matter.You may hear this phrase a lot:
"It depends."
>
As for the query plan, If i am not mistaken you can't get get query plans for queries that are: create table as select.What?
JG@TTST> explain plan for create table jjj as select * from product_master;
Explained.
JG@TTST> select count(*) from plan_table;
COUNT(*)
3
I can however commit the create table part and just call for the evalution of the Select part of the query; i believe it should be same.
"Optimizer" "Cost" "Cardinality" "Bytes" "Partition Start" "Partition Stop" "Partition Id" "ACCESS PREDICATES" "FILTER PREDICATES"
"SELECT STATEMENT" "ALL_ROWS" "2563" "586110" "15238860" "" "" "" "" ""
"UNION-ALL" "" "" "" "" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "512" "117222" "3047772" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "513" "117222" "3047772" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "513" "117222" "3047772" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "513" "117222" "3047772" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "513" "117222" "3047772" "" "" "" "" ""
This query plan was taken from sql developer, exported to txt, and the PROFILE table here has only 100k tuples.
Right now I am more concerned with testing the MODEL query. Which Oracle doesn't seem to be able any more... but that is a matter for another thread.
Regarding this plan. The Union ALL seems to be more than just a binary Operator... IT seems to be Neray.
The union all on that execution plan seems to be taking as leaf tables 5 99sono.Profile tables, and be making a table scan to them all. So I'd say that the RDBMS should only scan each database block once and not 5 times.
But: It doesn't seem to be so. IT seems like what oracle is doing is scanning completly each the table, and then moving on to next select statement in the UNION ALL. Because given the amount of source table that was read, 5 times greater than the size of the source table. Oracle didn't reuse read blocks.
But this is just my feeling.Your feeling is uninteresting. Telling us what you really hope to accomplish might be more interesting.
Anyway, in terms of consistent gets, how many consistent gets should the RDBMS be doing? 5
One for each table block?It depends.

Would someone be able to explain to me the following issue with Iphoto?
I ordered 8 same calendars for my soccer team and received them fine. Although a couple of pictures on it are a little off (out of focus). I need to order two more of the same calendars but when I go thru the process ireceive an error message saying:
"Unable to to assemble calendar" There is a problem with the photo with the file name "(Null)" The full resolution version of this photo either cannot be located or is corrupt. Please replace this photo or delete it from your calendar.
How can I fine this "corrupt" photo? How did it go thru with the first batch of calendars but won't go thru now?
Thank you for your help.Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start
with Option #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Having Problems With The Neo2 ? Read This!!!!
Hi,
i just bought a neo2 motherboard, with a p4 2,6 HT and 512 mb Kingston hyper ram ( 2 peaces of 256, else it won't use the dual bandwith :D)
In the beginning everything seemed fine, until i got some sudden reboots and other vague stuff. I read it could be the SB audigy messing things up. I removed the card and windows Xp pro runs fine now. no more sudden reboots or explorer not resonding crashes.
But, i still had problems with games crashing. I got reboots. After i set the "automatic reboot after crash" to false, i got blue screens or lock-ups in my games.
I wondered what it could be. Then i started to put my videocard ( a radeon 9700 pro 128 mb) in agp 4x mode instead of agp 8x! Now my games run without crashes, but benchmarks are not that high. 4780 marks with 3dmark 2003.
I think i will send msi and Ati a mail concerning this problem. I don't know if it is PSU related. Maybe the videocard demands a little more power in agp 8x mode.
Well, having probs with you're NEO2 ??
remove the sb Audigy and turn the agp back to 4 using smartgart ( it's located in you're display settings screen ).
First i tought it was a PSU related problem, because i swapped my 350 Watt enermax with a Q-tec 400 watt psu. The 400 watt PSU died while i was gaming. Maybe the enermax is the better PSU :D So, it could still be a PSU related problem. Maybe the agp 8x settings demands a lot more from you're psu. Anyway, i'll receive a 550 watt Antec PSU soon, so i can check this out....
Btw. I cant run the motherboard in anything better than "slow" mode. In all other modes Xp won't boot. I haven't tryed it since the AGP is at 4X, but i don't think it will matter.
Regards,
Welcome to the real world NEO :DOk.....
i raised the memory voltage setting in the bios from 2.65 to 2.8 and the agp voltage from 1.5 to 1.7
Everything seems fine, but games crash back to the desktop now without an error message or the either lockup.
Whatever i do, i can't make the mobo crash in anything but games!
Btw. the following message caught my attention, when i ran f1 2002 with directx 8.1. Since i have directx 9, i haven't seen it anymore. Maybe because the ati-drivers are made for directx 9....

Problem with the FOR statement.....again!
Hi everyone,
Well I'm still trying to do a car slideshow using external
files and can't seem to see the end. The current movie is here:
http://www.virtuallglab.com/projects.html
I also attach the code. My problem is I had originally set up
an animation with 2 pictures sliding in with some text, and then
wait 4 seconds before sliding out, and then next pictures and text
would slide in and so on, using a setInterval.
The problem is the FOR loop seems to skip the setInterval and
the function "wait", so it just loops quickly and jumps to last
picture, so on the example above, it just slides the last picture
(i=9) and that's it!
Can you not include another function within a FOR statement.
Or is there a way to tell the FOR loop to wait until all motion is
finished?
Any help greatly appreciated
import mx.transitions.*;
import mx.transitions.easing.*;
for (i=0; i<10 ; i++) {
var picLeft = "pics/"+i+".jpg";
var picRight = "pics/"+i+"b.jpg";
var txtToLoad = "text/"+i+".txt";
this.createEmptyMovieClip("leftHolder",1);
leftHolder.loadMovie(picLeft,i,leftHolder.getNextHighestDepth());
leftHolder._x = -200;
leftHolder._y = 15;
var leftTween:Tween = new Tween(leftHolder, "_x",
Strong.easeOut, leftHolder._x, 10, 2, true);
this.createEmptyMovieClip("centerHolder",2);
centerHolder.loadMovie(picRight,i+"b",centerHolder.getNextHighestDepth());
centerHolder._x = 180;
centerHolder._y = 250;
var centerTween:Tween = new Tween(centerHolder, "_y",
Strong.easeOut, centerHolder._y, 15, 2, true);
text._x = 600;
myData = new LoadVars();
myData.onLoad = function(){
text.carText.text = this.content;
myData.load(txtToLoad);
var textTween:Tween = new Tween(text, "_x", Strong.easeOut,
text._x, 420, 2, true);
myInterval = setInterval(wait, 4000);
function wait() {
var leftTweenFinished:Tween = new Tween(leftHolder, "_x",
Strong.easeOut, leftHolder._x, -200, 1, true);
var centerTween:Tween = new Tween(centerHolder, "_y",
Strong.easeOut, centerHolder._y, 250, 1, true);
var textTween2:Tween = new Tween(text, "_x", Strong.easeOut,
text._x, 600, 1, true);
clearInterval(myInterval);
***************************************************************************************** ***There is no way to tell a for loop to wait. That is not what
they do.
The entire for loop will execute (if possible, and it doesn't
enter some kind of continuous infinite loop) completely before each
time the frame is rendered.
If you want to spread things out over time you need to use
the setInterval -- but not inside a for loop! If you do that you
immediately set however many intervals as your loop has. In this
case you will also assign the ids for those intervals to the same
variable, effectively overwriting the value so you will never be
able to clear most of those intervals.
So you need to rethink you whole structure. Set up some kind
of counter and limit like this:
var slidesToShow:Number=10;
var curSlide:Number=0;
Then have your setInterval increment the curSlide each time
it is called and check to see if it has shown all of them. That is
where your "loop" comes in.
As for the other part of your question -- yes you actually
have two different issues going on -- again you cannot make a for
loop wait for anything. So no there is no way to pause it while you
wait for your tween to end. But you can be notified when a tween
ends.
Check out the documentation about the tween class in the help
files. There you will find the onMotionFinished event. So you can
set up one of those to start whatever needs to be started when the
tween has finished.
You should also use the MovieClipLoader class to load your
images, because you have no idea how long it will take to load
them. Using that class you get a nice event (onLoadInit) that tells
you when the asset is ready to be used.
Finally I'm thinking you might want to use setTimeout instead
of setInterval. It only goes once, while setInterval repeats
forever. So I would think your algorithm would be something like
this.
1. load external asset
2. when ready animate in and set onMotionFinished handler
3. when motion is finished start loading next asset and
setTimeout for 4 seconds.
4. when 4 seconds is up or the clip is loaded (which ever
takes longer) go to 2 and repeat.
If this is going to be run locally on a hard drive or CD you
won't have any problem with the length of time it takes to load the
external assets, but if it is over the web it will take time. -
Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
