Description
Hi,
I'm trying to enable the proxy_ssl_session_reuse with dynamic proxy_pass as per the following config.
server {
listen 80;
server_name localhost;
ssl_session_cache shared:SSL:20m;
ssl_session_timeout 4h;
proxy_ssl_session_reuse on;
proxy_ssl_protocols TLSv1.2;
proxy_ssl_ciphers
EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
proxy_ssl_server_name on;
proxy_socket_keepalive on;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
set $upstream_server https://myupstream.com;
location /test/ {
# forward the request id received in the headers to the
upstream
proxy_set_header X-Request-Id $http_x_request_id;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header Host "myupstream.com";
resolver 8.8.8.8;
rewrite ^/test/(.*) /$1 break;
proxy_pass $upstream_server;
# completely disable proxy cache
expires off;
sendfile off;
}
}
but the proxy module does not honor proxy_ssl_session_reuse.
On the other hands in the case of NOT DYNAMIC resolution it works fine. Example:
server {
listen 80;
server_name localhost;
ssl_session_cache shared:SSL:20m;
ssl_session_timeout 4h;
proxy_ssl_session_reuse on;
proxy_ssl_protocols TLSv1.2;
proxy_ssl_ciphers
EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
proxy_ssl_server_name on;
proxy_socket_keepalive on;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location /test/ {
# forward the request id received in the headers to the
upstream
proxy_set_header X-Request-Id $http_x_request_id;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header Host "myupstream.com";
resolver 8.8.8.8;
rewrite ^/test/(.*) /$1 break;
proxy_pass https://myupstream.com;
# completely disable proxy cache
expires off;
sendfile off;
}
}
Expected behaviour:
when I use variables in proxy_pass directive all the proxy_ssl* directive are honored (in the same way they are honored with no variables in proxy_pass)
Note:
See TracTickets
for help on using tickets.
That's expected behaviour. SSL sessions are cached within a corresponding upstream object, and using variables as in your example implies that the upstream object will be dynamically created for a single request and then destroyed. This effectively prevents SSL session caching from working. For SSL session reuse to work, consider using
proxy_passwithout variables, or refer to an existing upstream when using variables.
