can't find the option of cloudflare as cdn

It’s not an option in the CDN section. If you set up a Cloudflare account at cloudflare.com and route your traffic through that, the CDN is an integral part of their service and you have some limited options for controlling the CDN behavior, although nowhere near the control you have with one of the roll-your-own options.

In W3TC’s General Settings tab you should see a Network Performance & Security Powered by Cloudflare panel where you can enter your Cloudflare account details and gain some basic Cloudflare controls from within your WordPress admin screens rather than having to go to Cloudflare.com each time. Is that panel showing up for you?

Hi pxlar8,

Yes i can see it. It was under my nose all the time. Thanks a lot for helping me to find it.

By reading your explanation, another question came up in my mind: If cloudflare is going to do the caching, I don’t need to set up a self-hosted / File Transfer Protocol Upload (or any other setting on the plugin) anymore, do I?

Thanks once again and I hope my questions and your answers can help others.

I’m afraid I don’t have an authoritative answer on that myself. Hopefully someone else does. Cloudflare describes their service as “CDN-like” technology, and I believe it only caches the most requested static content, although I can’t find where I read that. Whether there’s any benefit to doubling up is something I don’t know for sure.

That’s fine pxlar8. Thanks anyways. Let’s hope someone else informs that.

Also (someone), i think I read it somewhere, that when using cloudflare with w3tc we don’t need to change the dns on the cloudflare’s account; is this info correct?

Thanks

No, but I recommend it.
