From 7dc6f4e25d21588249691aab8c6013c126eae258 Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Mon, 30 May 2022 21:25:32 +0300 Subject: Combining unknown headers during variables lookup (ticket #1316). Previously, $http_*, $sent_http_*, $sent_trailer_*, $upstream_http_*, and $upstream_trailer_* variables returned only the first header (with a few specially handled exceptions: $http_cookie, $http_x_forwarded_for, $sent_http_cache_control, $sent_http_link). With this change, all headers are returned, combined together. For example, $http_foo variable will be "a, b" if there are "Foo: a" and "Foo: b" headers in the request. Note that $upstream_http_set_cookie will also return all "Set-Cookie" headers (ticket #1843), though this might not be what one want, since the "Set-Cookie" header does not follow the list syntax (see RFC 7230, section 3.2.2). --- src/http/ngx_http_variables.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/http/ngx_http_variables.h') diff --git a/src/http/ngx_http_variables.h b/src/http/ngx_http_variables.h index f3f7f3c1c..6a661a256 100644 --- a/src/http/ngx_http_variables.h +++ b/src/http/ngx_http_variables.h @@ -57,8 +57,9 @@ ngx_http_variable_value_t *ngx_http_get_flushed_variable(ngx_http_request_t *r, ngx_http_variable_value_t *ngx_http_get_variable(ngx_http_request_t *r, ngx_str_t *name, ngx_uint_t key); -ngx_int_t ngx_http_variable_unknown_header(ngx_http_variable_value_t *v, - ngx_str_t *var, ngx_list_part_t *part, size_t prefix); +ngx_int_t ngx_http_variable_unknown_header(ngx_http_request_t *r, + ngx_http_variable_value_t *v, ngx_str_t *var, ngx_list_part_t *part, + size_t prefix); #if (NGX_PCRE) -- cgit
