Log Http Headers

Problem this snippet solves:

This simple rule logs all HTTP headers in requests and responses to /var/log/ltm. This can be helpful in troubleshooting.

Code :

when HTTP_REQUEST {
   set LogString "Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]"
   log local0. "============================================="
   log local0. "$LogString (request)"
   foreach aHeader [HTTP::header names] {
      log local0. "$aHeader: [HTTP::header value $aHeader]"
   }
   log local0. "============================================="
}
when HTTP_RESPONSE {
   log local0. "============================================="
   log local0. "$LogString (response) - status: [HTTP::status]"
   foreach aHeader [HTTP::header names] {
      log local0. "$aHeader: [HTTP::header value $aHeader]"
   }
   log local0. "============================================="   
}
