Using URI to rewrite host

I am trying to come up with a rule where the first directory name of the uri is used to rewrite the URL. an example will be:     http://www.foo.com/abc/doc/index.html =>   http://abc.foo.com...

What I trying to do is, we have implementation with Trafficshiled Security gateway in b/w BIG-IP and the servers. The Trafficshield needs to have a unique VIP for each hostheader. So, I need to have the BIG-IP change the host to be unique for each directory (which indicates different site within the servers) and then rewrite them on the way out.

I was playing with getfield to pick up the directory after the host and set tn as a variable value just to see if I can get them to collect the right strings.


when HTTP_REQUEST {
   set my_host [getfield [HTTP::uri] "/" 2] 
   set my_domain [getfield [HTTP::host] "." 2]
   log local0. "my host is $my_host.$my_domain.com"
        pool ts_pool
   }

I just need to find a way to rewrite the URI to what it was originally on the way out. Could it be as simple as storing the original URI in a variable and replace (on the way out) the one that was rewritten on the way in?

Thanks.

John
