RAM Cache - use different cache "buckets" based on URI string

Forgive the stupid questions, but by host header, are you referring to the actual host as in the "Host: x.x.x.x" in the HTTP GET request? If so, then the answer is yes, they are the same. All requests will be going to a single VS, that points to a single pool with 3 members.

 

 

If I understand the 2nd part correctly, I can set a CACHE::uri based on each request and if repeated requests match that it will pull from that cached data? How do I tie, in my example, the string all the way through the session when the first URL is the only URL that has the unique ID? And can I dynamiclly assign that string without specifying the actual unique ID and possibly use a varrible?
