Basic Caching Out of the Box

advanced caching varnish hit miss

Out of the box, your section.io Varnish configuration will cache static objects. It will also observe the HTTP headers already set in your application to decide if an object is cacheable or not.

section.io metrics will show you the object hit rate for each environment (development, test, staging and production).

As you develop your web application code you can observe the hit rate in each environment so you can work out if the web code you are building has the best HTTP headers for cacheability and ensure you are caching as much content as possible

Advanced Caching Configuration

Section.io gives developers complete control over their Varnish Cache configuration, allowing you to push your web speed to the extreme, caching dynamic content and even full HTML documents.

Edit and commit Varnish Control Language (VCL) changes within the section.io portal to configure cache settings and take advantage of the flexibility Varnish Cache offers. Test your changes in our local and testing environments: when you go live, your changes will instantly be distributed to all of section.io's globally distributed servers.

Cache settings include:

  • Device detection logic - change application behavior based on user devices detected
  • Rewrite URLs and change HTTP headers - make "off domain" objects cacheable
  • Set caching based on server side logic - strip unnecessary cookies, override the cache times
  • Modify Cache Control Headers - set a max age cache time at client side which is different to intermediary caches
  • Set Specific HTML Pages to Cache or Not Cache
  • Set result code dependent redirections
  • Use Edge Side Includes
