Confusing (well to me!) Profile issue

IIRC that redirect rewrite has changed a couple of times what it actually accomplishes. However what it broadly does is the HTTP profile snoops any redirects coming back from the poolmembers and re-writes them to come back to the VS. (I remember having problems moving from v4 to v9 because of the way in which the rewrites changed)

 

 

It's possible that what you were hitting was perhaps a websphere system redirecting elsewhere? Which then redirected to an https version of the original VS?

 

 

However the best way to discover exactly what was happening is to duplicate the problem (e.g. with a test VS pointing at the same pools) and then getting a tcpdump of the traffic (Both frontend and backend connections) and investigating the responses that were being sent from the websphere to the F5 and the responses from the F5 to the client.

 

 

Sorry, I can't be more detailed... But experience tells us that there are many ways this could be happening... The best way to determine exactly what is to view the traffic passing between the endpoints.

 

 

BTW. I tend not to use the redirect rewrite option, but use iRUles to acomplish he results. Because in the past I have found too many instances where things don't quite work as you'd like them to...
