annotate src/http/ngx_http_variables.c @ 4334:f8881d301d62
Fixed: some of $sent_http_* variables may contain header entries that actually
haven't been sent to a client.
The ngx_http_variable_headers() and ngx_http_variable_unknown_header() functions
did not ignore response header entries with zero "hash" field.
Thanks to Yichun Zhang (agentzh).
