nginx 0.6.33 *) Feature: now nginx returns the 405 status code for POST method requesting a static file only if the file exists. *) Workaround: compatibility with glibc 2.3. Thanks to Eric Benson and Maxim Dounin. *) Bugfix: the resolver did not understand big DNS responses. Thanks to Zyb. *) Bugfix: in HTTPS mode requests might fail with the "bad write retry" error. *) Bugfix: the ngx_http_charset_module did not understand quoted charset name received from backend. *) Bugfix: if the "max_fails=0" parameter was used in upstream with several servers, then a worker process exited on a SIGFPE signal. Thanks to Maxim Dounin. *) Bugfix: the $r->header_in() method did not return value of the "Host", "User-Agent", and "Connection" request header lines; the bug had appeared in 0.6.32. *) Bugfix: a full response was returned for request method HEAD while redirection via an "error_page" directive. *) Bugfix: if a directory has search only rights and the first index file was absent, then nginx returned the 500 status code. *) Bugfix: of recursive error_page for 500 status code.
