nginx 0.5.7 *) Feature: the ssl_session_cache storage optimization. *) Bugfixes in the "ssl_session_cache" and "limit_zone" directives. *) Bugfix: the segmentation fault was occurred on start or while reconfiguration if the "ssl_session_cache" or "limit_zone" directives were used on 64-bit platforms. *) Bugfix: a segmentation fault occurred if the "add_before_body" or "add_after_body" directives were used and there was no "Content-Type" header line in response. *) Bugfix: the OpenSSL library was always built with the threads support. Thanks to Den Ivanov. *) Bugfix: the PCRE-6.5+ library and the icc compiler compatibility.
