TCP iRule to find HTTP headers

I have a situation where I have an iRule that works once the user is using the HTTP protocol. Unfortunately, the same VIP handles a proprietary protocol from Oracle called T3. To use the iRule I need...

    I think you could limit the iRule to this:

    when CLIENT_ACCEPTED {
    HTTP::disable
    TCP::collect 4
}

when CLIENT_DATA {
    if { [TCP::payload 4] contains "GET" } {
        HTTP::enable
    }
    TCP::release
}

when HTTP_REQUEST {
    my irule
}

when HTTP_RESPONSE {
    my irule
}

    I'll expect the HTTP_REQUEST and HTTP_RESPONSE events will not be triggered when the HTTP profile is disabled.

Thanks,

 

My iRule has both GET and POST.

 

if { ([TCP::payload 4] contains "GET") || ([TCP::payload 4] contains "POST") } {

 

Thanks guys for all your great help (Niels van Sluis & Jason Rahm). I'm very positive that this will work once I get to implement it.
