Filter certain parts out from HTTP::header or HTTP::uri?

Our developers unfortunately love to have long SAMLResponse as part of the URI, which could also show up via referrer. I currently got an iRule I use to send a NCSA combined weblog to a syslog server and these long SAMLResponse cause lines to be cut off.

 

 

Anyone got a tip how to remove anything "SAMLResponse=.*" from URI or Referrer, so it doesn't get logged?

    Hi,

     

     

    You can use an iRule like the one in the post below to do this. The example was just removing the parameter from the URI, but you could use the same logic to sanitize the Referer header. Note that this wouldn't prevent the client from seeing the value--the app wouldn't see (or log) it.
