nginx-0.1.35-RELEASE import
*) Feature: the "working_directory" directive.
*) Feature: the "port_in_redirect" directive.
*) Bugfix: the segmentation fault was occurred if the backend response
header was in several packets; the bug had appeared in 0.1.29.
*) Bugfix: if more than 10 servers were configured or some server did
not use the "listen" directive, then the segmentation fault was
occurred on the start.
*) Bugfix: the segmentation fault might occur if the response was
bigger than the temporary file.
*) Bugfix: nginx returned the 400 response on requests like
"GET http://www.domain.com/uri HTTP/1.0"; the bug had appeared in
0.1.28.
