nginx 0.8.37 *) Feature: the ngx_http_split_clients_module. *) Feature: the "map" directive supports keys more than 255 characters. *) Bugfix: nginx ignored the "private" and "no-store" values in the "Cache-Control" backend response header line. *) Bugfix: a "stub" parameter of an "include" SSI directive was not used, if empty response has 200 status code. *) Bugfix: if a proxied or FastCGI request was internally redirected to another proxied or FastCGI location, then a segmentation fault might occur in a worker process; the bug had appeared in 0.8.33. Thanks to Yichun Zhang. *) Bugfix: IMAP connections may hang until they timed out while talking to Zimbra server. Thanks to Alan Batie.
