Help with F5 config with VS on Port 443 and Pool member on Port 8080

THe application is Jenkins which is runing on Port 8080

I don't have any specific experience with this application, and I'm sure there are at least a few ways to deploy it. What you need to do is run a client side HTTP capture (HTTPWatch, Fiddler, etc.) and watch the HTTP communications to the browser. Start looking for attempts to reach the http:// port 8080 URL from the browser. Once you find these, go back the previous HTTP response (or maybe a few responses back) and look for where that URL is getting sent to the browser. It'll either be in an HTTP 30x redirect, in the Location header, or somewhere in the payload. Once you know where it's coming from, you can more easily solve the problem with a quick iRule fix.
