New Revision: 4359
Log:
Merge of r4275, r4276, r4278, r4279:
Fixes for proxy_set_header, fastcgi/scgi/uwsgi_param inheritance:
*) Fixed proxy_set_header inheritance with proxy_cache (ticket #45).
Headers cleared with cache enabled (If-Modified-Since etc.) might be
cleared in unrelated servers/locations without proxy_cache enabled
if proxy_cache was used in some server/location.
Example config which triggered the problem:
proxy_set_header X-Test "test";
server { location /1 { proxy_cache name; proxy_pass ... } }
server { location /2 { proxy_pass ... } }
Another one:
server {
proxy_cache name;
location /1 { proxy_pass ... }
location /2 { proxy_cache off; proxy_pass ... }
}
In both cases If-Modified-Since header wasn't sent to backend in
location /2.
Fix is to not modify conf->headers_source, but instead merge user-supplied
headers from conf->headers_source and default headers (either cache or not)
into separate headers_merged array.
*) Fixed proxy_set_header inheritance with proxy_set_body.
*) Separate functions to merge fastcgi/scgi/uwsgi params.
No functional changes.
*) 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.
