Enable cache for logged in users

[roryashfordbentley]

Hey, first of all thanks for the excellent plugin, it works incredibly well out of the box!

I have been poking through the plugin source code and I can't seem to find the logic that disables/prevents caching for logged in users.

What I am hoping is possible is that I can create a custom config file like this Surge Configuration Example. And setup some logic to enable caching for logged in users with a certain custom role (essentially a role that only has frontend access).

If you could point me in the direction of how Surge currently identifies logged in users I'd really appreciate it.

WP use wp_get_nocache_headers() to set no-cache headers for logged in users.

It seams, You can modify this header to control cashing in Surge. Example: somewhere in the theme's functions.php:

add_action( 'wp', function(){
    
    if( is_user_logged_in() ){
        header_remove( 'Cache-Control' );
    }
} );

I tried using the header_remove() code snippet above, and it wasn't working properly for me. I tried nocache_headers() instead, and that seems to be working.
