New Revision: 4279
Log:
Fixed fastcgi/scgi/uwsgi_param inheritance.
The following problems were fixed:
1. Directive fastcgi_cache affected headers sent to backends in unrelated
servers / locations (see ticket #45).
2. If-Unmodified-Since, If-Match and If-Range headers were sent to backends
if fastcgi_cache was used.
3. Cache-related headers were sent to backends if there were no fastcgi_param
directives and fastcgi_cache was used at server level.
