Hello all--
I'm publishing a Microsoft Sharepoint Services web server on my ISA 2004
server (Windows Server 2003). Sometimes when we click on a link, it gets
rejected. Error message = 12217 The request was rejected by the HTTP
filter.
When I look at the logs, I get a message that says "Blocked by the HTTP
security filter: URL normalization was not complete after one pass."
The URL is automatically generated (an ASP page, I guess) and is quite
long:
http://192.168.200.2/sca/Lists/General%20Discussion/NewForm.aspx?Source=
http%3A%2F%2Ftmp%2Eafscstar%2Eorg%2Fsca%2FLists%2FGeneral%2520Discussion
%2FAllItems%2Easpx
Other pages generated the same way don't seem to have a problem. For
example:
http://192.168.200.2/sca/Lists/FAQs/NewForm.aspx?Source=http%3A%2F%2Ftmp
%2Eafscstar%2Eorg%2Fsca%2FLists%2FFAQs%2FFlat%2Easpx
Is it a length thing? (i.e., Does size really matter?)
For troubleshooting purposes, we created a link that would generate an
even longer URL, and it got blocked, too.
Is there a way to change this behavior?
Thanks,
Rob
