nginx: src/http/modules/ngx_http_not_modified_filter

annotate src/http/modules/ngx_http_not_modified_filter_module.c @ 4437:3a1507f48686 stable-1.0

Merge of r4372, r4373, r4374: SCGI fixes: *) Fixed incorrect use of r->http_version in scgi module. The r->http_version is a version of client's request, and modules must not set it unless they are really willing to downgrade protocol version used for a response (i.e. to HTTP/0.9 if no response headers are available). In neither case r->http_version may be upgraded. The former code downgraded response from HTTP/1.1 to HTTP/1.0 for no reason, causing various problems (see ticket #66). It was also possible that HTTP/0.9 requests were upgraded to HTTP/1.0. *) Removed duplicate function declaration. *) Removed error if there is no Status header. The SCGI specification doesn't specify format of the response, and assuming CGI specs should be used there is no reason to complain. RFC 3875 explicitly states that "A Status header field is optional, and status 200 'OK' is assumed if it is omitted".
