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.
