Just wondering if someone can tell me which is best:
Content-Length: 0

the missing one. "0" is broken.
Content-Lenght: 0
is certainly not broken. Maybe you are confusing this with
ERR_ZERO_SIZED_REPLY which is when Squid doesnt receive any reply at all
before the connection was closed by the server, not event HTTP headers.
It is not broken, but surelly misleading. I had a bug with a
proprietary apache 1.3 module, which was used to serve dynamic content
for a commercial CMS. This module started to send a "Content-Lenght: 0"
header, when the content was delivered from NFS.
This bug caused mod_proxy (from Apache 1.3) and some versions of IE not
to be able to retrieve the page successfully (and show a blank page,
instead).
Apache's implementation of SSI (mod_include) simply removes this
header, when sending dynamic content ("size calculation is costly on
dynamic pages", they say).
no problem. If the server supports chunked encoding, nothing bad should
happen.
Squid is HTTP/1.0 so there is no chunked encoding.

Henrik
