nginx: src/imap/ngx_imap_handler.c annotate

annotate src/imap/ngx_imap_handler.c @ 525:09b42134ac0c release-0.1.37

nginx-0.1.37-RELEASE import *) Change: now the "\n" is added to the end of the "nginx.pid" file. *) Bugfix: the responses may be transferred not completely, if many parts or the big parts were included by SSI. *) Bugfix: if all backends had returned the 404 reponse and the "http_404" parameter of the "proxy_next_upstream" or "fastcgi_next_upstream" directives was used, then nginx started to request all backends again.
