proxy_ssl_conf_command
The `proxy_ssl_conf_command` directive specifies SSL-related configuration commands for proxy connections in NGINX.
Description
The proxy_ssl_conf_command directive allows users to set configuration parameters specifically for SSL when NGINX acts as a reverse proxy. It accepts two arguments: the command name and the command value. This functionality enables customization of SSL parameters on a per-proxy basis, allowing adjustments to SSL behaviors, such as verification settings, to be applied to specific upstream servers instead of globally across all connections.
The command name must correspond to an SSL configuration command valid for the OpenSSL library, and the command value is the associated argument for that command. This directive can be used in http, server, and location contexts, making it flexible for various configurations depending on the structure of the server blocks and the specific routing of requests. Notably, this can enhance the security and performance of SSL handshakes for upstream servers, providing finer control over how NGINX interacts with its backend services using SSL/TLS.
Config Example
location /example {
proxy_pass https://backend;
proxy_ssl_conf_command 'SomeSSLCommand' 'SomeValue';
}Ensure the SSL command is supported by the OpenSSL version used in NGINX.
Incorrect command names or values can lead to runtime errors.
Using this directive requires careful understanding of OpenSSL commands, which can lead to misconfigurations.
Excessive SSL command configurations can potentially degrade performance if not correctly managed.
