annotate src/core/ngx_connection.c @ 537:c9ad0d9c7d59 release-0.1.43

nginx-0.1.43-RELEASE import *) Feature: the listen(2) backlog in the "listen" directive can be changed using the -HUP signal. *) Feature: the geo2nginx.pl script was added to contrib. *) Change: the FastCGI parameters with the empty values now are passed to a server. *) Bugfix: the segmentation fault occurred or the worker process may got caught in an endless loop if the proxied or FastCGI server sent the "Cache-Control" header line and the "expires" directive was used; in the proxied mode the the bug had appeared in 0.1.29.
