nginx 0.6.15 *) Feature: cygwin compatibility. Thanks to Vladimir Kutakov. *) Feature: the "merge_slashes" directive. *) Feature: the "gzip_vary" directive. *) Feature: the "server_tokens" directive. *) Bugfix: nginx did not unescape URI in the "include" SSI command. *) Bugfix: the segmentation fault was occurred on start or while reconfiguration if variable was used in the "charset" or "source_charset" directives. *) Bugfix: nginx returned the 400 response on requests like "GET http://www.domain.com HTTP/1.0". Thanks to James Oakley. *) Bugfix: if request with request body was redirected using the "error_page" directive, then nginx tried to read the request body again; bug appeared in 0.6.7. *) Bugfix: a segmentation fault occurred in worker process if no server_name was explicitly defined for server processing request; bug appeared in 0.6.7.
