 Not sure if this is considered a bug or if it's known.

 When varnish is talking to a HTTP/1.0 web server, and using ESI, the
 chunked Transfer-Encoding used by the ESI engine does not work.

 This seems to be because when processing ESI - varnish keeps the HTTP/1.0
 of the original response, but tries to use Transfer-Encoding which is an
 HTTP/1.1 feature.

 Many browsers can cope with this (Command line tools such as curl, wget,
 LWPs GET)  Webkit based browsers also cope with it.  But Firefox and
 Internet Explorer obey the HTTP spec and ignore the chunked encoding.
 This results in the hex content-lengths for each chunk being displayed in
 the browser.

 Please feel free to contact me if you need any more information.
