How to disable Cloudflare Polish for a specific User Agent?

I would like to disable Cloudflare Polish for a specific User-Agent so that it can take original images. Is it at all possible?

I tried using Transform Rules to add a header to the response, but unfortunately it had no effect.

Did you try purge the cache after creating this rule?

Yes. But even for newly uploaded images it doesn’t work.

You are adding a HTTP response header from Cloudflare to the user. This will be added after the object is retrieved from the Cloudflare cache.

You can probably get what you want in a few ways.

One solution is to use a URL Rewrite rule to append a special query parameter to the URL (polish-=off or similar), and then on your Origin append the no-transform Cache-Control directive when you see that query parameter. There is no need to use the no-cache, must-revalidate directives.


Thanks for the idea! I added rewrite rule for this User Agent and such code in .htacces:

<If "%{QUERY_STRING} =~ /polish=off/">
    Header set Cache-Control "no-transform"
