Chunked transfer encoding probably?

Yes, because squid doesn't support transfer encoding yet.
Maybe disabling of chunking by forcing http/1.0 protocol between proxy and
client would solve the problem between apache proxy and client too.

I would suspect this is the case as well. I recently resolved a problem with
a similar java applet. I forced HTTP 1.0 between the proxy server and the
backend server and turned off keepalives and the applet works fine through
mod_proxy.
