I have searched the forums, technical libraries, and talked to developers and administrators and so far no solution for my problem. We have a web application developed about 5 years ago. It’s used by 2000 people a day. For 2 months now, 10 users - who never had issues before - started getting this HTTP 500 Error. Here are some things to consider:
-
The application has not been changed for several months
-
The users never had a problem before
-
If we log on with their user ID from our computers we don’t have any problems (tried from several computers)
-
They have the latest patches from IE on their computers
-
The server has been set to no limit for “Maximum Post Data Field” and “Maximum size of Request Content”
-
The server log shows “HTTP Web Server: Invalid POST Request Exception”
Any ideas of what could be happening?
TIA!

The person is in a deny access list.

Check adware, spyware, firewall blocking software on those PCs that seem effected. Any Java in the application? Have you tried Firefox? Even if you don’t support it, try to see if the problem is duplicated w/ it. Clear cache, files, reset default browser settings.

It’s HTTP. We had “show friendly errors” checked and unchecked. We tried to clear cache, etc. Nothing is working…
Thanks for your input!

Is the url Http or https (ssl)?
We had an issue (like others on this forum) with 500 errors. Turning off “Show Friendly HTTP Errors” (an IE advanced option) fixed it.

I know that this is an old thread, but I just had the same problem and thought that I had really screwed something up.
Check the database properties and on the first page make sure that in the “Web Access” section that “Don’t allow URL open” is not mistakenly checked.
