BIGIP-LTM-Version-9.4.8:irule to extract username from HTTP request

Calling HTTP::payload in HTTP_REQUEST will return any of the HTTP payload that was included in the packet(s) which contain the HTTP headers. It's not guaranteed to return any or all of the payload unless you explicitly tell TMM to collect the payload with HTTP::collect and call HTTP::payload in HTTP_REQUEST_DATA.

 

 

If that works for your testing, it would be simpler to use than a stream filter and STREAM::expression based iRule. But if you want a guarantee, you could use the stream filter or HTTP::collect/HTTP::payload.
