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...
application delivery
iRules

    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.

My first thoughts are something like this: (the HTTP profile will be configured on the VIP)

 

` when CLIENT_ACCEPTED { TCP::collect 4 } `

 

` when CLIENT_DATA { if { ([TCP::payload 4] contains "GET") || ([TCP::payload 4] contains "POST") } { HTTP::enable How to add the iRule??? } else { HTTP::disable How to remove the iRule??? } TCP::release } `
