Only if Communicator find the URL in its own cache. Most of our users
run without a disk cache in Communicator, relying completely on squid.
So Communicator only sends If-Modified-Since headers if it finds the URL
in its memory cache. It seems to always include Pragma: no-cache,
regardless of its cache settings and the contents of its disk and
memory cache. Go figure!
