nginx 0.8.44 *) Change: now nginx does not cache by default backend responses, if they have a "Set-Cookie" header line. *) Feature: the "listen" directive supports the "setfib" parameter. Thanks to Andrew Filonov. *) Bugfix: the "sub_filter" directive might change character case on partial match. *) Bugfix: compatibility with HP/UX. *) Bugfix: compatibility with AIX xcl_r compiler. *) Bugfix: nginx treated a large SSLv2 packets as plain requests. Thanks to Miroslaw Jaworski.
