It's hard to guess what's going wrong. If the server is sending a 100 response code, then the iRule should not pass the first if in the HTTP_RESPONSE event and ignore the rest. I'd try to throw in some logging and see what shows up on the /var/log/ltm log file.

 

 

when HTTP_RESPONSE {
    set status [getfield [HTTP::status] " " 1]
    log local0. "HTTP Status: $status"
    if { [HTTP::header "Content-Type"] contains "text/html" && $status == 200 } {
        log local0. "Collecting [HTTP::header Content-Length]..."
        HTTP::collect [HTTP::header Content-Length]
    }
}
when HTTP_RESPONSE_DATA {
    if { [HTTP::payload] contains "Application Error" } {
        log local0. "HTTP::payload contains Application Error - sending 302 response"
        HTTP::respond 302 Location "/error/"
    }
}

 

 

I'm wondering why you are doing a getfield on the HTTP::status. Are you finding that it is containing more than just the numeric status code?
