What is the issue you’re encountering

We are trying to differentiate the cache based on if it’s mobile and desktop. To do this we want to use a X-Subdomain header which gets set to M if on mobile or empty/unset on desktop. We do this Extension:MobileFrontend/Configuring browser auto-detection - MediaWiki in varnish Which our live config is: puppet/modules/varnish/templates/default.vcl at master · miraheze/puppet · GitHub and puppet/modules/varnish/templates/default.vcl at master · miraheze/puppet · GitHub. I’m having problems doing this in CF. We are on the enterprise plan.I tried setting it in modify request header which adds the header but the cache doesn’t work the way I expect it to. I have tried snippets which now it doesn’t cache. So it works changing between mobile and desktop but it’s not cache so it’ll hit the backend…

So essentially how I was trying to do this is:

  • Create a modify request header rule to add X-Subdomain if it matches the criteria.
  • Create a cache all rule and then added the x-subdomain to include header

None of this changed the cache. You can see that at 100% free, ad-free wikis, request yours today! - Miraheze. click on mobile view on the footer and then click on the logo or the site name “meta”. The mobile view should be shown instead desktop is.
