Hi Dalton,
you need to turn DSR off in Cookie Hashing scenarios
In DSR the Serveriron does not process the Answer, and therfore would
not "see" any Set-Cookie responses required to make Cookie Hashing work.
If you use Cookie Switching you will parse the Request Cookie value
and look for a specific string - based on this value you will send
the request to a defined real server.
Since no part of the response is required for this to work, this
should work in DSR scenarios as well.
something like:
csw-rule "test1-8080" header "Cookie" pattern ".pattern1"
csw-policy "virtual-test"
match "test1-8080" forward 1025
server real test1 x.x.x.x
port 8080 server-id 1025
server virtual virtual-test y.y.y.y
port http csw-policy "virtual-test"
port dsr
port http csw
should work ....
unfortunenately i do not have a testbox at hand at the moment...
