HTTP::redirect restrictions?

Hi,

Im trying to redirect all requests from an IP to a specific page, to a completely new URL. The redirect works but it always goes to our base domain no matter what I specify as redirect target. IRule would probably explain the situation better

Lets say the page abc.php is on 'some-host.my-site.com'(some-host.my-site.com/abc.php), the Irule below only redirects to my-site.com, regardless of the fact I asked it to go to google.com instead. Any input would be helpful

The plan was to apply this to only the virtual server for 'some-host' since this rule should not apply to any other host behind the domain

when HTTP_REQUEST {
    set http_path [HTTP::uri]
    if {$http_path contains "/abc.php" } {
        if {[IP::addr [IP::client_addr] equals xx.xx.xx.xx]}{
             use pool some-host
             }
         else {
             HTTP::redirect "www.google.com"
           } 
    }
}

    Correction: the specific IP is the only ones that should get to the page - I stated the requirement incorrectly.

    With redirects, you have to specify the full url, including the protocol (http/https)

      Actually, no :) . For example if you simply want to redirect to a different URL you can only use something like: HTTP::redirect "/new_URI" Of course , the normal thing to do is to modify the URI on its flight ( HTTP::uri /new_uri ); however, could be the case in which we do need to actually send a redirect and get a fresh new request to this URI from the client.

    It sounds like you want to preserve the URI portion of the original request. If so you would want to modify it as so:

             HTTP::redirect "http://www.google.com[HTTP::uri]"

    I also use a little trick to ensure that I keep them on the same protocol the arrived on by doing the following:

    when HTTP_REQUEST {
    if {[TCP::local_port] eq 80} {
        set proto "http"
    }
    elseif {[TCP::local_port eq 443} {
        set proto "https"
    }
    else {
        log local0. "UNKNOWN PORT!"
    }
    if {[HTTP::uri] contains "blah_blah_blah"} {
        HTTP::redirect $proto://www.google.com[HTTP::uri]
    }
}

      Also, note that the HTTP::redirect method will issue a 302 which is "Temporarily moved." It may not be appropriate for all applications. If you need to issue a redirect for "permanently moved" you will need to do the following: HTTP::respond 301 Location "http://www.google.com[HTTP::uri]"
