Upstream SSL sessions may be of a noticeably larger size with tickets in TLSv1.2 and older versions, or with "stateless" tickets in TLSv1.3, if a client certificate is saved into the session. Further, certain stateless session resumption implemetations may store additional data. Such one is JDK, known to also include server certificates in session ticket data, which roughly doubles a decoded session size to slightly beyond the previous limit. While it's believed to be an issue on the JDK side, this change allows to save such sessions. Another, innocent case is using RSA certificates with 8192 key size. --- src/event/ngx_event_openssl.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/event/ngx_event_openssl.h b/src/event/ngx_event_openssl.h index 25e023b01..b7aaaca75 100644 --- a/src/event/ngx_event_openssl.h +++ b/src/event/ngx_event_openssl.h @@ -142,7 +142,7 @@ struct ngx_ssl_connection_s { #define NGX_SSL_DFLT_BUILTIN_SCACHE -5 -#define NGX_SSL_MAX_SESSION_SIZE 4096 +#define NGX_SSL_MAX_SESSION_SIZE 8192 typedef struct ngx_ssl_sess_id_s ngx_ssl_sess_id_t; _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx-devel
