iRule Optimization

Hi,

I have some comments about your irule:

POST data are not included in HTTP_REQUEST but in HTTP_REQUEST_DATA. when you will have to log these informations, there will be:

• [HTTP::request] in HTTP_REQUEST event
• [HTTP::payload] in HTTP_REQUEST_DATA event

if you want to parse only POST data, you can use this irule::

when HTTP_REQUEST {
     Collect Post Data to be parsed in HTTP_REQUEST_DATA
    if { [HTTP::method] eq "POST" }{
        set clength 0
        if {[HTTP::header exists "Content-Length"] && [HTTP::header Content-Length] <= 1048576}{
          set clength [HTTP::header Content-Length]
        } else { set clength 1048576 }
        if { [info exists clength] && $clength > 0} { HTTP::collect $clength }
    }   
}
when HTTP_REQUEST_DATA {
    set payload [HTTP::payload]
     Convert POST Data to URI with query string to extract password parameter
    set password  [URI::query "/?$payload" password]
     Replace Post 
    set new_data [string map "password=$password password=[string repeat "*" [string length $password]]"  $payload]
}
