2 related questions: I'm trying to find a way to concat multiple samples to use in a stick table. Basically in my frontend I pattern match on the request path to determine which backend to send a request to. The client requests also have a client ID header. I want to rate limit based on a combination of this pattern that matched, and the client ID. Currently the way I do this is an "http-request set-header" rule that adds a new header combining a unique ID for the pattern that matched along with the client-ID header. Then in the backend I have a "tcp-requst content track-sc2" on that header. This works, but I'm wondering if there's a better way.
Secondly, the above works, but when I do a "show table mybackend" on the stats socket, both the "conn_cur" and "use" counters never decrease. They seem to be acting as the total number of requests, not the number of active connections. Is this a bug, or am I misunderstanding something? -Patrick
