Note the "Also there are other variables" in the same paragraph. The $http_* variables provide access to all headers, including any custom ones. And it is documented as: $http_name arbitrary request header field; the last part of a variable name is the field name converted to lower case with dashes replaced by underscores Therefore, you may either use the $http_operation variable to access the header you are looking for. Or you may take a look at the source code to find out how it's implemented. Take a look at the src/http/ngx_http_variables.c, functions ngx_http_variable_unknown_header_in() and ngx_http_variable_unknown_header() (first one says the header should be searched in r->headers_in.headers list, second one does actual search). -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
