NGINX helper plugin 'adds support' for caching?

Hi,

I was just reading the NGINX helper plugin page and I see that it’s also developed by rtCamp … It also looks like NGINX helper needs a few modules to work, such as :

  • nginx-srcache-module
  • ngx_cache_purge_module

The description says that the plugin will ’ add support ’ for this. However, what does this mean ? I thought that adding modules means that NGINX needs to be recompiled from scratch with required modules … How can the plugin 'add support ’ or add these modules if I already have NGINX (not EE) installed ? Or do I need an EE setup for this plugin to work correctly ?

Thanks, Lex
