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.
