Comment 1 for bug 377351

That´s indeed something that should be changed, and it´s not very difficult to do. Anyway, as far as I know, the kdu_server doesn´t allow normal unchunked responses. The only related available parameter I´ve found is one that allows to specify the maximum length of a chunk. If the proxy doesn´t support chunks, by the time being, there is not any available solution yet.

I think Squid 2.6 already partially supported chunked messages. The problem is that it converted chunked messages into unchunked messages, so in this case JHelioviewer would fail (and it shouldn´t do it). According to something I read, the last version 3.1 of Squid fully supports chunked messages. In this case our application should work without problems.
