Greetings! The task is to install and configure Varnish 4 with cache purge via mod_pagespeed.
Servcer: ubuntu 18.04, nginx, php ftm, mod_pagespeed, vestacp & wordpress (woocommerce).
You also need to implement the display of cached pages, regardless of the presence of additional parameters in url.
I mean, if you go to the url [login to view URL], then the cached page [login to view URL] should be shown.
