From 5544756296e5abaecb5f640753d6de939b701035 Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Fri, 10 Feb 2017 17:49:19 +0300 Subject: [PATCH] Cache: increased cache header Vary and ETag lengths to 128. This allows to store larger ETag values for proxy_cache_revalidate, including ones generated as SHA256, and cache responses with longer Vary (ticket #826). In particular, this fixes caching of Amazon S3 responses with CORS enabled, which now use "Vary: Origin, Access-Control-Request-Headers, Access-Control-Request-Method". Cache version bumped accordingly. --- src/http/ngx_http_cache.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/http/ngx_http_cache.h b/src/http/ngx_http_cache.h index 5b135e209..f9e966409 100644 --- a/src/http/ngx_http_cache.h +++ b/src/http/ngx_http_cache.h @@ -24,10 +24,10 @@ #define NGX_HTTP_CACHE_SCARCE 8 #define NGX_HTTP_CACHE_KEY_LEN 16 -#define NGX_HTTP_CACHE_ETAG_LEN 42 -#define NGX_HTTP_CACHE_VARY_LEN 42 +#define NGX_HTTP_CACHE_ETAG_LEN 128 +#define NGX_HTTP_CACHE_VARY_LEN 128 -#define NGX_HTTP_CACHE_VERSION 4 +#define NGX_HTTP_CACHE_VERSION 5 typedef struct {
