Problem Description:

Users get the following error while accessing ALIM Web:

 

Bad Request - Request too long

HTTP Error 400. The size of the request headers is too long.

 

Cause:

After the user visits an ALIM Web site multiple times, the browser cookies are appended with session data and the length eventually exceeds the allowed/configured limit.

Solution:

Clearing temporary internet files and cookies resets it.

Workaround:

There is a windows registry workaround to increase the maximum header size.
