CloudFlare Page rules for XenForo 2.2.0

[RyderForNow]

Hey all,

I've upgraded to XF 2.2 today and - while I'm not sure if its the direct cause - my website stopped working when I use CloudFlare's Proxying (Orange Cloud). No proxying works just fine, though. So first, is this also happening to anybody else? And second, if not, could anybody share their site rules / configs with me?

Thanks

Can't imagine a page rule affecting it. Are you getting any specific error or anything in your server logs? The only Cloudflare Page Rule that I use for XenForo 2.2 sites is this:



Just forcing client-side and edge caching of CSS files with a .php extension.

This site (xenforo.com) uses Cloudflare (with Cloudflare proxying/orange cloud) and seems to be fine as well.

Just forcing client-side and edge caching of CSS files with a .php extension.

FYI, I don't have this rule and I see css.php as a cache path.

Not sure what you mean by "cache path", but if you are referring to the CSS on physicsforums.com, it's not being cached at Cloudflare's edge.

Compare that to a request for your main logo (.png file): cf-cache-status: HIT

There are some details about what files extensions Cloudflare will cache by default and what the cf-cache-status header responses mean: https://support.cloudflare.com/hc/e...-s-CDN#h_a01982d4-d5b6-4744-bb9b-a71da62c160a

DYNAMIC

Cloudflare does not consider the asset eligible to cache and your Cloudflare settings do not explicitly instruct Cloudflare to cache the asset. Instead, the asset was requested from the origin web server. Use Page Rules to implement custom caching options.

What is odd is that Cloudflare says only one page rule is triggered per URL, so if you have multiple global rules, you have to choose just one.

Couldn't you apply whatever went with rule #1 to also be part of rule #2?

 

[nodle]

@digitalpoint do you just recommend running all three rules like in this post:

CloudFlare Page Rules

For xf 2.x, what are the three must-have default Cloudflare Page Rules that everyone should be using? Odd that there's no real definitive guide on this (that I can find anyway).

xenforo.com

Or just using the .CSS one only?

 

[digitalpoint]

Of the three there, the two for styles and js and be effectively done with proper web server configuration. The only one that can't be done with web server configuration is the one for the css.php (since Cloudflare looks at the file extension, NOT mime type).
