nginx 0.8.34 *) Bugfix: nginx did not support all ciphers and digests used in client certificates. Thanks to Innocenty Enikeew. *) Bugfix: nginx cached incorrectly FastCGI responses if there was large stderr output before response. *) Bugfix: nginx did not support HTTPS referrers. *) Bugfix: nginx/Windows might not find file if path in configuration was given in other character case; the bug had appeared in 0.8.34. *) Bugfix: the $date_local variable has an incorrect value, if the "%s" format was used. Thanks to Maxim Dounin. *) Bugfix: if ssl_session_cache was not set or was set to "none", then during client certificate verify the error "session id context uninitialized" might occur; the bug had appeared in 0.7.1. *) Bugfix: a geo range returned default value if the range included two or more /16 networks and did not begin at /16 network boundary. *) Bugfix: a block used in a "stub" parameter of an "include" SSI directive was output with "text/plain" MIME type. *) Bugfix: $r->sleep() did not work; the bug had appeared in 0.8.11.
