Re: [squid-users] NONE/411 Length Required

[ moving to squid-dev ]

 From what I can see, the site is using JavaScript to do autocomplete
on a search field. The autocomplete requests use POST, but without a
body.

With Firefox, this results in a POST request without a body; i.e., it
doesn't have transfer-encoding *or* content-length.

Such a POST request is legal (although atypical; Safari and I think
others will include a Content-Length: 0 to signal no body explicitly).
See <http://tools.ietf.org/html/draft-ietf-httpbis-p1-messaging-06#section-4.3
>.

I think the right thing to do here is for Squid to only 411 when
there's a transfer-encoding present; if there's no content-length,
it's safe to assume 0 length.

Cheers,
