Is there a restriction on length of Http request posted to a Iplanet Web Server ?

I am submitting an Http Request by POST method to my server. The request will be received and forwarded by Iplanet Web Server to a clustered Weblogic environment, which will then be handled by Java Servlets. The problem I am facing is that when the length of the request shoots up to around 2000 bytes, NES doesn't receive and forward the request to Weblogic. There is no fixed cut-off for the length, it keeps fluctuating.
I observed the following after hitting the server hundreds of times with Http Requests that vary in length.
1) If length of Request is below 1500 bytes, request always goes through successfully.
2) In a range of 1500 bytes to 2000 bytes, request fails most of the times. (Around 80 %)
3) Requests with length above 2000K invariably fail, though it just worked for a 2.4K request on one occasion (out of some 100 hits)
Note that by "length of request", I mean the data I post through Http Request (I just have a single parameter in Http request having the literal "XML" as key and a well formed XML document as value. That is equivalent to submitting a HTML form just having a text area called "XML" containing a XML document. )
I presume that the length of actual Http Request is slightly greater than that of XML (probably by around 100 bytes).
My Iplanet documentation says that the upper limit on the length of a POST Http Request is 64 K, which is way above the value (2-3 K) at which I am facing the problem.

Hi Ganesh
Did you check the HTTP Persistent timeout of your server? Check the value which has been set up by default. Try increasing the timeout value and try again.
follow these steps it might solve your problem:
(1)Goto Web Server Administration Server, select the server you want to manage.
(2)Select Preference >> Perfomance Tuning.
(3)set HTTP Persistent Connection Timeout to your choice (eg 180 sec for three minutes)(note : if you are posting large amount of data or file increase the value accordingly)
(4) Apply changes and restart the server.
*Setting the timeout to a lower value, however, may prevent the transfer of large files as timeout does not refer to the time that the connection has been idle. For example, if you are using a 2400 baud modem, and the request timeout is set to 180 seconds, then the maximum file size that can be transferred before the connection is closed is 432000 bits (2400 multiplied by 180)
If this doesnot solve your problem notify me

After installing iPlanet Web Server v6 SP2, there is error message: https-admserv60 cannot be found??

After installing iPlanet Web Server v6 SP2 on Windows 2000 SP2, error message in the event log shows up. "The description for Event ID ( 0 ) in Source ( https-admserv60 ) cannot be found."
"The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: startup: server started successfully."
The iPlanet 6SP2 seems to work fine but these error message occur after rebooting the server. There is actually 2 messaages: one for the admin server and the
other for the actual web server instance. Both state
'server started successfully' but these messages still
appear.
Any ideas how to correct this?
Thanks,
JD Trinaca

this will occur, as the 6.x servers do not use the lodctrl to place the perf monitor messages in the registry...as long as the server starts & runs ok, you can ignore these particular errors

Read of HTTP Request POST parameters failed:Read timed out

Hi !
Any one seen this exception . any ideas of the cause?
java.lang.RuntimeException: Read of HTTP Request POST parameters failed: Read timed out
at org.apache.catalina.connector.HttpRequestBase.parseParameters(HttpRequestBase.j ava:665)
at org.apache.catalina.connector.HttpRequestBase.getParameterValues(HttpRequestBase.java :737)
at org.apache.catalina.connector.RequestFacade.getParameterValues(RequestFacade.java:170 )
Thanks,

Assuming there is nothing wrong with
org.apache.catalina.connector.HttpRequestBase.parseParameters
I can only think of 2 things:
1. The timeout is set for an extremely short time in the Apache settings (server.xml의)
2. The client application is sending the POST verry slow or incorrect. For example the
client says that the POST is 500 long than sends 200 and leaves the connection open.
You can try and post the following:

HTTP Submit Button - How to post data to a Web Server

HTTP Submit Button - How to post data to an IIS Server
Steveoruni - 09:50am Sep 4, 2007 Pacific
Hello,
I have created a simple form in LiveCycle designer. The form only has some check boxes, radio buttons and text fields for users to fill out. Everyone in my office is on webmail so the Email Submit button is not a smooth option for getting the xml data back to me.
I would like to use the HTTP Submit button to allow users to submit their form data back to me but I am having trouble. I would like the xml files to end up in a directory on the web server.
I set up an IIS 6 server and granted the Write right to the anonymous web user account. When I fill out the PDF form and click the HTTP Submit button it doesn't seem to work. Are there any special configuration changes I need to make to my IIS server to allow this data to be posted?
Should this plan work? Should I be able to have users use the HTTP Submit button to post their data right to my IIS web server or is there some Adobe server I need to buy for this simple form? I'd also be happy if this could work with Apache; it doesn't need to be IIS. I guess my main issue is that I don't know how to get either web werver to accept data in an HTTP post and save it as a file.
Also, I noticed that when I configure a standard button and set the Control Type to "Submit", there is an option on the Submit Tab to change the Submit As setting to "PDF". Does this mean that my users can fill out my form with Acrobat Reader and HTTP Submit the form to my web server as a PDF complete with their data? If not that's fine, I would be sufficiently happy if the users could post their XML files to the web server so I can open them in the form with Acrobat Professional.
I am lost and would appreciate any helpful feedback.
Thanks,
Steve

HI again,
I want to have a pdf fillable form opened on a link.Once user has entered data, the user clicks a button(or some action to invoke saving). At this point I want the filled pdf file to be saved on a certain directory.
How can save a filled pdf form in pdf format on a certain directory?
Is it possible to dynamically give the final pdf a name so that it doesnt overwrite everytime it saves the file?

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout).

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout). It is as if the server has decided that the client has timed out during the file upload. The default setting is 30 seconds for AcceptTimeout in the magnus.conf file. This should be ample to get the file across, even increasing this to 2 minutes just produces the same error after 2 minutes. Any help appreciated. Apologies if this is not the correct forum for this, I couldn't see one for iPlanet and Web, many thanks, Kieran.

Connection timeout when using iPlanet web-server uses Weblogic 6.1 proxy server to proxy requests to an HTTP server

Are there any known issues concerning using DIGEST-MD5 SASL authentication with iPlanet Directory Server 5.0 on Windows NT 4.0?

I am developing support for the DIGEST-MD5 sasl mechnism on a c-ldap client. I am using the evaluation version of the iPlanet Directory Server 5.0 which lists DIGEST-MD5 as a supported SASL mechanism. The server is running on NT 4.0 After installing the Directory Server with the test database, a changed the passwordStorageScheme from the default of SSHA to clear text. I then added my test user. When I run my test I always get back a resultCode of 49 (invalidCredentials). The digest-challenge I receive from the server and my digest-response are shown below. I have satisfied myself that the calculation of the response directive in the digest response is correct. Does anyone see any problems in the digest response or have any other suggestions? Is there a known problem with the iPlanet Directory Server 5.0?
digest-challenge:
realm="BGB2.ndp.provo.novell.com",nonce="Ed8UPLXsWaC6CN",qop="auth",algorithm=md5-sess,charset=utf-8
digest-response:
username="uid=bgbrown,ou=people,dc=siroe,dc=com",realm="BGB2.ndp.provo.novell.com",cnonce="A9IuPJKr30RiwL",nc=00000001,qop=auth,digest-uri="ldap/BGB2.ndp.provo.novell.com",response=97061205298e5ebaf206c8ac3598fdce,charset=utf-8,nonce="Ed8UPLXsWaC6CN"

Found the answer. When the username is an LDAP DN it needs to be proceeded by "dn:".
example: username="dn:uid=bgbrown,ou=people,dc=siroe,dc=com"
The server also accepts a simple uid value.
example: username="bgbrown"

How do I set iPlanet Web Server 4.1 HTTP Response Header to use expires so that the browser will cache content longer

I want to add in all html files returned the "expires" value.
Based in HTTP 1.1, I think it is possible by adding the META tag between the <HEAD> and </HEAD>:
<META> HTTP_EQUIV:"expires" CONTENT="Sun, 21 Jun 2002 15:05:00 GMT" </META>
I include this in my html file (but "expires" doesn�t work :(( ). Which options are necessary to modify in the WS?
How does the internet options of the browser influence?
PD:(This is a question posted last 5/28, but is has no response yet.)

The above reply does not take into account that I am trying to use GROUP POLICY EDITOR to make it the default browser.

Oracle iPlanet Web Server - HTTP listeners based on hostnames

Regarding the HTTP listeners configuration I read:
IP Address — A Valid IPv4 or IPv6 address. “” implies that the HTTP Listener will listen to all IP addressed for the configured port.*
(no mention to hostnames)
I have tested that it is also possible to specify a NAME in the IP Address field and the effect is the same if I specify the explicit IP the name is associated.
Is it a supported but not documented feature ?
In other words can I use this feature for my deployment ?

It seems like I was wrong, you can not use hostname in <ip> element. Code doesn't try to convert hostname to <ip> address.
When you said that it worked for you, can you show the output of "netstat -an | grep <listen_port>".

Make HTTP request with Idoc Script

Is there a way to make an HTTP request to a remote host with Idoc?
For example, in PHP you could do:
file_get_contents('http://website.com/');
Does Idoc have a similar method?

You can also use the HTTP-DC project.... You don't
need Web Enterprise for this. From what I can tell,
this is available in L.x on....
There is api documentation in M.2 (with scant
examples.)
There's a special process to put the project in your
repository (it isn't installed in the repository in
the standard install,) the documentation in M.2
(probably in M.0 too, AFAIK) that tells you how to do
this (look for HTTP-DC in the online help.)
I haven't done much with it yet, I've just installed
it. If anybody out there has examples, that'd be
great. I'll try to contribute more the moment I get a

Disabling Weblogic's http server port - Using an external web server

Hi,
We are using Weblogic 8.1 as application server and IWS as web server. We have
siteminder web agent configured on the web server for implementing authentication
and authorization.
All our requests first go to the web server which redirects them to the application
server.
Since Weblogic itself has a http listen port, user can still send requests directly
to the application server(which does not have any siteminder configuration on
it). Is it possible to ensure that all http requests made directly to the application
server are not processed so that the user is forced to hit the web server first.
Thanks,
Akash

When you say redirect, do you mean you use an HTTP redirect to send it to your
WLS servers URL? Or do you mean you proxy the requests from the webserver to
the WLS instance? In the former case, you must expose WLS's HTTP server to the
clients in order to redirect them to the address and you will not be able to
stop them from going directly there. In the case of the latter, you can put
your WLS instance behind the firewall so external users can't get to it. If you
also need to protect it from internal users you should probably not use
siteminder as your authentication mechanism. You may be able to configure
siteminder so that it has to authenticate itself to send requests to weblogic
and then protect all weblogic resources with that role requirement.

Filter to convert HTTP request to JNLP arguments fails every other time

I want to pass HTTP request parameters to a Java Web Start program as arguments. I have implemented a filter which adds the arguments from the request parameters using XML DOM, and I also set the Last-Modified date to the current date/time. [ I am sort of thinking I should put the date as the file date -- not sure ]
The filter works successfully ever other time I invoke a given URL. If I switch parameters, it looks like the filter works every time.
When the filter works, there are HTTP GET and HEAD requests. When the filter fails, there are three HEAD requests and one GET request. Using the apache soap TCP Tunnel/Monitor, it looks like the HTTP request parameters aren't being passed for the second GET.

Varad and Sc0tt,
Thank you both for your responses.
Varad – Yes, I can/will reduce the amount of data so it does not cause the tabular form to go over the 2000 field limit. If that is not possible, I will at least make the users aware of this issue. Since the same data is used for the other pages in the application, the users might want to keep all the data.
Sc0tt – thanks for providing the information for your environment and settings. To plan for the future, we will have to set the value to something high also, around 8-10K range, and adjust later if we have to.
Thank you both, I will mark both of your answers as helpful and the question as being answered.

Soap UI HTTP Request Parameter

Hi,

<ns0:Order xmlns:ns0="http://BizTalk.HTTPAdapterDemoApp.Message_XML">
<ItemNumber>01</ItemNumber>
<Quantity>499</Quantity>

if Qty<500 then Status= 'Approved' else Status= 'Denied'.
I am sending this input message to BizTalk from console application and I am able to receive the response from BizTalk.
Now I want to send this message to BizTalk from Soap UI.
Can any one help me, How many parameter do I need to create in Soap UI to work it properly?
Thanks UK

Here it goes.
I can able to send the HTTP request of input schema and getting the response by using console application.
While using Soap UI, I am getting below errors.
In Biztalk console, I am getting below error,
The BizTalk HTTP receive adapter failed to initialize itself. Possible reasons:
1) Receive location URL is not created/configured correctly.
2) Receive location is not enabled.
3) HTTP receive adapter is not running under a user that has access to management and message databases.
4) Isolated host instance is not created for HTTP Receive adapter.

<ul> <li>IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when
this error occurred.</li> <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.</li> <li>IIS was not able to process configuration
for the Web site or application.</li> <li>The authenticated user does not have permission to use this DLL.</li> <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li>
