Logging HTTP header that is longer than the maximum allowed

Just to follow up on this...

 

 

After testing in 10.2, it looks like TMM resets the client connection before HTTP_REQUEST is triggered. This is also matches what is stated in SOL8482:

 

 

Error Message: HTTP header exceeded maximum allowed size of

 

http://support.f5.com/kb/en-us/solutions/public/8000/400/sol8482.html

 

 

So it isn't possible to use an iRule to log the long header names in HTTP_REQUEST.

 

 

If the error happens consistently, you could try to capture a tcpdump to find the long header. Or you could just increase the max header size until you don't see the error anymore.
