Subject: Added storeEntryValidLength() based on Henrik's version.
X-Git-Tag: SQUID_3_0_PRE1~6280
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ffe4a36726c26c1852174fdbf8cb776671515bef;p=thirdparty%2Fsquid.git

Added storeEntryValidLength() based on Henrik's version.
If content-length and hdr_size are given, the object is
ejected if the sizes don't match the actual object size.
