# Caching removes https form src url’s in AMP pages

 * For some reason, the cachining module removes https:// from certain URL’s and
   changes it to // instead. This causes problems for AMP pages and generates an
   error with Google: “User-authored JavaScript found on page: The attribute ‘src’
   in tag ‘amp-iframe extension .js script’ is set to an invalid value”
 * In my AMP page, it change this:
    `src='https://cdn.ampproject.org/v0/amp-analytics-
   0.1.js` to this: `src='//cdn.ampproject.org/v0/amp-analytics-0.1.js`
 * I solved this by excluding /amp/ pages from caching, but I would prefer that 
   I don’t need to do this…

 * Same behaviour causes issues with Google Maps.
