Subject: Stop parsing response prefix after discovering an "HTTP/0.9" response.
X-Git-Tag: SQUID_4_0_9~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=617b7ccaa640802a9fc1e23e95726d4279d9556f;p=thirdparty%2Fsquid.git

Stop parsing response prefix after discovering an "HTTP/0.9" response.

Otherwise, our "X-Transformed-From: HTTP/0.9" headers are going to
be ignored, and the rest of the received bytes are going to be parsed
(and modified!) as an HTTP/1 response header, followed by message body.
