the regex does not match; you have told varnish to cache files ending
in .jpeg but this test url will fail so you will still have the cookie

without knowing how to reverse engineer your webapp (which is what i
have found you need to do to use varnish usually), it seems to me you
would want to match on the string
"_propertyslider_WAR_propertysliderportlet_img-name" as well as strip
cookies, and set your cache behaviour in fetch
