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.

    Vernon, The Video_pool is up and has 1 member server. The default pool members don't host anything at /video.

     

    I will make the change on the rule and re-run and will provide the logs right away.

     

    Thanks!

    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."
