iRule(s) using Data Group based on host and uri

So we are trying to implement single VIP (one Virtual IP) for multiple clients (websites) and would like to achieve that using iRules that has Data Group assigned. I was able to get the iRule working which has DG based on host. However I need to be able to accept certain requests based on couple of URIs as well. One of the URIs should work on port 80 and other on 85. Below is the iRule I have which works fine based on host for 443.

when HTTP_REQUEST {
  set pool [class match -value -- [HTTP::host] equals test_url]
  if {$pool ne ""} {
    pool $pool
   }
}

How do I append or add more iRules to manage my URI based traffic? I believe iRule for port 80 URI needs to be on 80_VIP. Also we need to have http to https redirect rule for everything other than above specified URI. URIs are as below --

/XYZ.svc* -- port 80

/example/attach/ABC.svc* -- port 85

URI (string) will be same for all clients but the pool (value) is different. So how do I get the request go to the right pool based on URI as well as host in the prefix? In my tests, all requests made for different client websites are going to the first pool in the data group.
