Full Page Cache requires a few steps to verify it is working.

These are the most common solutions to issues we see.

Solution #1: Alter your Magento configuration

  1. Go to Extendware -> Manage Extensions -> Page Cache -> Configure -> Developer -> General
  2. Enable the “Footer Widget
  3. This will put a black bar on the bottom of the store so you can see if it is loaded from cache or not. 
  4. Clear browser cookies and go to the home page. 
  5. Refresh your home page. 
  6. Verify is says “level: primary” or “level: lightening”.

Solution #2: Run a pagespeed test on your Magento Shop

  1. Go to http://www.webpagetest.org/ and click Advanced Settings
  2. Set the Connection to Fios. 
  3. Set it to “First View and Repeat View” 
  4. Set the Number of Tests to 3. (Generally set the location to Dulles, VA because those servers usually don’t delay the tests.)
  5. Run the test and and look at the First Byte Time
  6. Then, go to Extendware -> Manage Extensions -> Page Cache -> Configure and disable the page cache.
  7. Re-run the test and verify you see a difference in First Byte Time.
