nginx-0.3.53-RELEASE import *) Change: the "add_header" directive adds the string to 204, 301, and 302 responses. *) Feature: the "server" directive in the "upstream" context supports the "weight" parameter. *) Feature: the "server_name" directive supports the "*" wildcard. *) Feature: nginx supports the request body size more than 2G. *) Bugfix: if a client was successfully authorized using "satisfy_any on", then anyway the message "access forbidden by rule" was written in the log. *) Bugfix: the "PUT" method may erroneously not create a file and return the 409 code. *) Bugfix: if the IMAP/POP3 backend returned an error, then nginx continued proxying anyway.
