Avoiding to save cookie file on the client's disc

Hello folks,
I don't use client variables in my application, but app. has
saved client-cookie file on my HDD. For example:
CFID
31987
www.site.com/
1536
3950493312
31986928
4097529456
29784164
CFTOKEN
68660018
www.site.com/
1536
3950493312
31986928
4097629456
29784164
I don't want client/visitor can conclude that I'm using CF.
CF files in the app. have not cfm or cfc extension, of course.
How can I prevent the app. to save any cookie files on
clients machine? Is it possible?
Thanks,
d.

That cookie is used to track sessions. You can disable the
cookie in the <cfapplication> tag in your Application.cfm
file at the root of your website.
http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/tags-pa3.htm#wp1097308
<cfapplication setClientCookies="No">
If you need sessions, but don't want to use cookies, you will
need to manually append #URLToken# to the end of all URLs on your
site (form posts, <a href> links, javascript redirects,
etc).

Can't copy files to network client's folders

We just switched from ARD 2.0 to ARD 3.0. ARD 3.0 is a great product - if it works. I can only copy files to ARD-clients, if I copy to the local hard disk, i. e. if it is a local client or if it is a network client and I copy to the top level of the volume. But if I copy files to the network client's desktop it doesn't work. I think the reason is that the network client's desktop is located on the server and not on the local hard disk.
The same problem occurs if I use the new feature to copy files from or to a client using drag-and-drop with the observe window. It works with the client's local hard disk, but not with folders located on the server. This time there is no error message, but the message "waiting" - and the waiting never terminates.
Has anybody a helping idea? Thanks!

I had the same problem, but I managed to fix it.
In WGM check that the sharepoint of your users Home Folder is set to owner root with Read and Write permissions.
I also created an ard_admin group in WGM and enabled open directory management on the client Macs. (Page 62 of the ARD admin Guide.)

Set cookie file name

I work with WAS5.1 against IE6.
My cookie file create and store at the client's hard disk in
C:\Documents and Settings\<user_name>\Cookies.
Currently the name of my cookie file is <user_name>@<aplication_name>[<number>].txt
How to set constant name to cookie file?
Or how to set name independent from aplication_name?

May be using RSEF. If not changing the name, you can certainly control the cookies nicely. I have used it once in my previous projects it works Nice.

I want to read a file on the client side

Hi all,
I want to read a file on the client side, then the server show the contents of that file.

Signed applet sounds cool - I guess Microsoft's ActiveX technology would be the mirror of this.
Write you file access code as you normally would and then just drop it in a applet and JAR it up.
Use keytool to sign it - users will be requested to accept/review your certificate in order to grant file-access permissions.
Warm regards.

One thread is enough.

You could have bumped it instead. Also, you still just posted a junk of unformatted stuff. Furthermore, for HttpClient support ask at an HttpClient mailing list of rorum.

How to transfer file from one client to another client?

hello,
i have some questions and hope you all can help me..thanks a lot first..
Here are the questions:
i) How can i send a file from one client to another client using RMI?
ii) Does the client(sender) need to send the file to server, then server save it and then send it to another client(receiver)?
iii) If using RMI, a client can receive two files from same client(sender) or different client(sender) at a same time? how to do it? when both of the files come in from same port, how to differenciate them?
iv) For your information, i am doing the File Transfer Server-client application which sender can send any file to other client. Can you give me any ideas? thanks..
Last, thanks again..

Your questions reflect some ambiguity in terms.
"Client" and "server" are commonly used in two different senses:
1. Technical sense: A client process makes requests, and a server process fulfills the request (provides a service).
2. IT sense: A client computer (process) makes requests of a server (computer) process, and the server (computer) processes the request.
In the first case, any computer might be a client, or a server, or both, depending on the processes being executed. In the second case, the computers are assigned some role.
So: If you wanted to, you could implement client/server processes communicating between two peer computers, using RMI.
This may not be what you wanted; if you really want to distinguish client and server computers, then the answer is that yes, you will probably put files into intermediate storage on the server computer.
Finally, you probably do not have to worry about port conflicts if you use RMI; while the initial client server contact is established through a registry operating on a standard port, the actual RMI communications is established using random ports, one for each link.

I cannot delete cookies after updating to 9.0.1, also when opened, I have 2 new cookie files that disappear when FF is closed.

I have uninstalled/reinstalled 9.0.1, the same thing happens. Checked my Profile, cookies.sqlite is there when FF is closed or uninstalled. When installed and opened, I have 2 new files, cookies.sqlite-wal and cookies.sqlite-shm, along with cookies.sqlite. Is this the reason I can't delete cookies? Also I have, and have had enabled AdBlock Plus and Privacy Browsing. After updating, I can't post anything to FF Support (this is my 4th attempt, finally used Safari to post) and files under Tools, such as Clear History are accessible, I shouldn't have a History to delete.
(1st edit)
OK. I reinstalled FF 9.0.1 from Safari, but not directly from Mozilla. I used CNet, now things are working like they should. I have no cookies listed, except the ones I want. Private Browsing is working properly. However, I still have those 2 extra cookie files; -wal and -shm.
(2nd edit)
I spoke too soon. After accessing sites that I frequent, the 'ad' cookies are back (adbright, realmedia, 247realmedia) and the site cookies are eliminated, not there, gone. Now I can't login to anything and am back to Safari to access FF Support Forum. Do I have a bug? Someone please help, I'm desperate, I hate IE, Safari, Chrome, etc. They have neither the level of ad and pop-up elimination that Firefox has; nor, do they have the level of customization that Firefox has. The 2 extra cookie files, -wal and -shm, are still there when FF is open, and gone again when FF is closed. One more thing I noticed, I have a Chrome Support Application file in my Library. Could the Chrome cookie file interfere with FF cookies? I wouldn't think so, I have Safari, as well, and neither browser has ever interfaced with the other before.
(3rd edit)
I have uninstalled/reinstalled FF, all of my add-ons and also tried deleting the cookies.sqlite document from the FF Profile file, to no avail. I have counted, there are 14 sites listed in the Preferences>Privacy>Show Cookies pane (no pun intended) and they are all "ad" sites. These sites are also listed as blocked sites in Adblock Plus. Until someone answers, I give up, I don't know what else to do. There was only the one time that the cookies were gone from the Show Cookies pane, every other time I uninstalled/reinstalled anything, they were still there. So, until someone helps me, I'm stuck. The only thing I have not done is deleted the Profile file altogether. That is the last thing I want to do, unless I can save my bookmarks somewhere to move back after reinstallation. If this isn't rectified within a few days, I may just try that, too.

Do you have an extension like TACO (Abine) or TrackerBlock that maintains a set of OPT-OUT cookies?
* Targeted Advertising Cookie Opt-Out (TACO): https://addons.mozilla.org/firefox/addon/targeted-advertising-cookie-op/
* TrackerBlock: https://addons.mozilla.org/firefox/addon/trackerblock/
* Beef Taco (Targeted Advertising Cookie Opt-Out): https://addons.mozilla.org/firefox/addon/beef-taco-targeted-advertising/
If you do then you need to disable or uninstall such an extension.
If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted. 
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.

You never delete a Time Machine backup by dragging it to the Trash. You are supposed to use the TM application to manage the backups. What you will need to do now is to simply erase the drive using Disk Utility.

Saving The Report File (PDF) on Client Machine/PC

Hi Everyone,
I am using Oracle Application Server 10g (10.1.2). I have a form that calls a report (both forms and report version are 10.1.2) with ASYNCHRONOUS option and creates a file in PDF format. The report is running fine and is creating the PDF file fine BUT on the application server.
I need to know if there is a possibility of either creating the file on the client machine/pc or transferring the file from application server to client PC. I would prefer the first option that is to create the file on client PC so the client can print or browse the report later. The second option would be ok if there is no solution for first option but I am assuming that it would take twice as much time. First to create the report on Application Server then to transfer the file from AS to client PC.
I have already included webutil library and object library but could not find a way to save the file on client PC using any of the APIs.
I would appreciate if some one provide me detail information. I mean syntax on how to either create the file on client PC or how to transfer the file created on application server to client PC. I would like to know where the report is created on Application server as the path will be required for transfer.
Thanks in advance.
Khalid

Instead of just creating the file, open the file in a
browser using rwservlet. That way the client can see
it and save in his PC whenever he wants to.
Try:
...write code to get report id...you must be already
having this...
then continue....
:global.report_server_name:=<servername>;
reports_servelet:='/reports/rwservlet';
REPORT_MESSAGE := RUN_REPORT_OBJECT(REPORT_ID);
vjob_id :=
substr(report_message,length(:global.report_server_na
e)+2,length(report_message));
hidden_action :=
reports_servelet||'/'||'getjobid'||vjob_id||'?server='
||:global.report_server_name;
--WEB.SHOW_DOCUMENT(hidden_action);
Basically you get the objid for the report you ran
and open it in the browser.
Hope this helps.Hi,
First of all thanks for you kind reply. Actaully user has an option to preview report and it is working fine. The reports run and display under browser as either PDF or HTML depending on option selected by user. These reports can be saved on client machine without any problem as you mentioned.
The problem with this form is that as soon as it execute the report it exit out of form. So the reports that are previewed run under SYNCHRONOUS mode and reports that are creating files run in ASYNCHORONOUS mode. I can run preview reports also in ASYNCHOROUS mode and I have already tried it by creating TIMER and WHEN_TIMER-EXPIRED trigger and commenting EXIT_FORM built-in. But as mentioned since the form exit out WHEN_TIME_EXPIRED does not fire and it does not display the report on the browser. I can see the status of the report in print queue when it is finished successfully.
If the report is not displayed after running in ASYNCHOROUS mode then I will be unable to save the file. That is the reason we created the FILE creation option and thought we will find a way to create/save the file on client PC but I am having hard time to do that.
I am sure I have made myself clear. Bottom line is that previewing a report in a browse is an option but will not work for long reports and if we run in background then it will not display in a browser as form exits after calling the run_report_object to run report so WHEN-TIMER-EXPIRED is not there to show the report when it is finished.
Thanks
Khalid

That's a kernel panic and indicates some sort of problem either with the computer's hardware or software. Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. It would help to post the panic log: Mac OS X- How to log a kernel panic.
Meanwhile, try booting the computers into Safe Mode then restarting normally. If this is simply a disk repair or cache file problem then this may fix it.
You can also try creating a new admin account on each computer then booting into the new account. This would help determine if the problem is related to a bad file in the user accounts.

I can't drag and drop iTunes music files into Roxio Jam 6 anymore and, now I have to import music one song at a time by using the " " or "-" buttons on the bottom. What is going on? G5 Dual 2 Ghz and OS 10.4.11

Hi. I have not used Roxio Jam for quite a long time and I just wanted to make a few CDs. Jam used to work easily and well. I have a problem. I can't drag and drop iTunes music files anymore and, now I have to import music one song at a time by using the "+" or "-" buttons on the bottom. What is going on? I trashed the preferences file and restarted Jam to no avail. I also have selected that Jam should open files with iTunes in the Jam preferences. I have a G5 DP 2Ghz PPC machine with OS 10.4.11, iTunes 9.2.1 and Quicktime's version is 7.6.4. I have 2 GB of RAM and the machine has dual 1.25 Ghz. processors plus a 500 GB HD. Can anybody give me any suggestions?
Thanks in advance,
Larry

I found an solution.
Uninstalling AirParrot as well as the two offending AirParrotDriver.kext and APExtFramebuffer.kext files in System>Library>Extensions was the fix. All problems disappeared.

Can no longer drop a MIDI file into iTunes library

Using Tiger on a G4 iMac, I could drop a MIDI file into my iTunes library and convert it to an mp3 (or other format).
Can't get this to happen now that I'm using Leopard on a new machine (see below) - or is there a different way of doing it in Leopard?
With thanks,
Gilly

Answering my own question - had iTunes set to Show Duplicates - therefore couldn't see MIDI I dropped in.
