Subject: Re-compute Range response content offset after an FTP response was adapted.
X-Git-Tag: SQUID_3_4_0_3~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4d48a7c21fa451c7f32a096ea0b1dcb24160d742;p=thirdparty%2Fsquid.git

Re-compute Range response content offset after an FTP response was adapted.

Moved HTTP-only offset calculation code to the general ServerStateData code so
that [converted-to-HTTP] FTP responses can use it. FTP code computes the range
offset on its own earlier, but we must REcalculate in case the response is
adapted into a response with a different (or no) content range.
