The drawback will be that your proxy won't be able to accept "normal" HTTP
session any longer.

They were broken during a fix of another problem in the handling of the
streams. I need to work on the MUX part again, so consider for it for now
not stable.
But, if you use the normal setting, the number of connections from your
mirror server to the proxy should be limited, as connection are reused,
and as Jigsaw doesn't cut the alive connection after a small timeout (only
after a huge timeout :) ).
Hope this helps,
