Plone Support Deployment & hosting

we use nginx in front for various reasons:

  • is easier and much cleaner to do the rewrites and configure some stuff (like add/modify Expires headers) in nginx
  • we can easily block some requests like access to non-existent PHP scripts in nginx
  • we can apply rate limiting to some areas of the site like the search form
  • we can cache some HTTP response codes like 301, 302 and 404
  • according to some old performance measures nginx is a little bit faster for static content than Varnish
  • if you need to enable HTTPS you will have to deal with nginx in front anyway

so what pass nginx is cached in Varnish 30%-95% of the time, and only a few request pass to the Plone instances.
