iRule redirect URI to another pool

When users go ";, they should be redirected to a different pool. Somehow the iRule below is not working. What am I missing? Any comment is appreciated. Thanks!   when HTTP_REQUEST { if { [HTT...

My apologies. I forgot square braces around the logged HTTP::path. The code should be:

 

when HTTP_REQUEST { 
    log local0. "PATH = ([HTTP::path])"
    if { [HTTP::path] starts_with "/video" } { 
        log local0. "  .. starts_with /video"
        pool Video_pool 
    }
}

 

In any case, it appears that you are occasionally matching, so at least in those cases, the rule is doing what you instruct. What suggests that it is failing? You mention a "404". I presume that the default pool members don't host anything at /video/*. Are you certain that Video_pool has at least one member that is up and that you are not using persistence on the flow?

You may try adding this:

 

when LB_FAILED {
    log local0. "Trapped LB_FAILED from client [IP::client_addr]"
}

 

which will be raised if the pool call fails to select a pool member.

Hi Vernon, Below are the log output after making the change on the rule. I'm still getting error 404 "The requested URL /video/ was not found on this server."
