Cloudflare experiments

So I am currently running an Edge Workers experiment.
https://blog.cloudflare.com/cloudflare-workers-unleashed/

What I'm doing is attempting to solve the mixed content problem (displaying http images on a https page) whilst also increasing privacy and improving page load times.

The experiment goes like this:

• Find all images in comments
  
• Proxy them via an Edge Worker at the path /p/ on this site
  
  

The benefits:

• All images served from this domain
  
• HTTP2 means that the page will load faster
  
• The 3rd party images will be placed in my Cloudflare cache
  
• Fewer requests to third parties, and the ones that are sent aren't made by your browser
  
  

The bugs so far:

• It obscures the real URL of the image
  
• Amusingly it isn't working for http images, only https ones
  
  

I may reverse this, but for anyone that notices this is what is happening.
