Description

According to RFC2616, a 304 Not Modified response SHOULD/MUST NOT include other entity-headers for a strong/weak cache validator request to prevent inconsistencies between cached entity-bodies and updated headers.

However, for a GET request w/ Accept-Encoding header, lighty w/ mod_compress includes Content-Encoding entity-header field within a 304 response. And this DOES confuse some proxy software, including squid, and client browsers about their cached objects.

Reference: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5

Simple patch file is attached.
