Without a Content-Length header Squid has no choice but to close the
connection. The message has to be delimited, and in HTTP/1.0 there only
is two message delimiters:
a) Content-Length
b) Connection closed

HTTP/1.1 adds other delimiting methods, but Squid does not yet fully
support HTTP/1.1, and those other delimiting methods are one of the
HTTP/1.1 features not yet supported.
