nginx-0.3.22-RELEASE importrelease-0.3.22

    *) Feature: the ngx_http_perl_module supports the $r->args and
       $r->unescape methods.

    *) Feature: the method $r->query_string of ngx_http_perl_module was
       canceled.

    *) Bugfix: segmentation fault was occurred if the "none" or "blocked"
       values was specified in the "valid_referers" directive; the bug had
       appeared in 0.3.18.
