Problem figuring out how to rewite what is sent to pool

Sorry, I have been out on vacation for the weekend. Thanks for responding.

 

 

We have 2 servers on the backend that can generate an URL. By default it looks like this; https://server.ip/W.aspx?9293430

 

 

Both generate the same format as well you can put anything between the https:// and the /W.aspx?. I wanted to have it generate something like this; https://FQDN/tr1/W.aspx?23kd93 and https://FQDN/tr2/W.aspx?234f3234

 

 

That way I can tell which URLs are coming from which server. On the front end, it looks like the above, and depending on the dir (/tr1/ or /tr2/) I will send it to that pool, strip off the dir and just give it the ./W.aspx? to that server to retrieve the image and pass it back to the client.

 

 

I hope this makes sense.

 

 

Thanks
