nginx 0.1.43 *) 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 bug appeared in 0.1.29.
