You don’t need the script anymore using Amazon’s origin pulls. Using S3 can be beneficial, though, if you cannot beat S3 in terms of latency.

Keep in mind that the first request won’t be immediately served by CloudFront – there will be a small delay caused by Amazon loading that file. Furthermore Amazon’s file retaining and expunging policy is secret and therefore files might get pulled several times (not only once) from your servers or S3.

Using Redis does have some advantages in certain scenarios:

– When VFS cache pressure has to be increased
– When multiple load balanced nodes need access to the same cache, especially on a cold start
– When other apps pull content from posts and pages

In these cases, DB queries can be largely avoided once one or several nodes have sufficiently primed the cache.

I’m working on something sort of similar, which is what led me to read this. In short, Redis is not a single magic bullet when it comes to WP caching. However, when used sensibly, it becomes quite useful.

Ich würde mir mal ein Kochbuch oder eine Kochsendung der Art “Wie mache ich ganz ordinäre Speisen?” wünschen. Da würde man erfahren, wie man Bratkartoffeln mit Spiegelei, Schnitzel und Klopse machen kann, ohne erstmal bei Mutti anzufragen.

Aber nein, das wäre ja zu wenig elaboriert.

C B, the plugin won’t make your WordPress installation run from the CDN. It is for static files only, such as images or movies.
The plugin doesn’t upload a thing. It just rewrites links. And yes, you will have to push that content manually to your CDN – unless the latter implements “origin pull”. Then that is done automatically by the CDN itself.

Ron, that’s indeed strange behaviour. Feel free to write me an email and we will sort that out. I will need: 1) a page with and 2) w/o the pluginbeing enabled (HTML as attachment, please) as well as 3) a screenshot w/ how you have the plugin configured.

Suggestions? Questions? Drop me an email!

It appears the rewrite is only working on the front page of my blog. My CDN has the other pages mirrored, but the plugin is not changing the URLs except on the main page. I would like to send you some info not on a comment.

Thanks,

Ron

First of all, thank you for creating and sharing this script!

Q: Assuming that one is using Amazon’s CloudFront, now that CloudFront supports origin pulls (http://aws.amazon.com/cloudfront/faqs/#How_do_I_use_Amazon_CloudFront), is there a need for this script?

Thanks!

But, I realized that the wordpress sites itself is still running from the non-CDN domain.

If I add a new image to a page, the content isn’t pushed to the CDN without me manually transferring the file. I thought the plugin would detect the file missing on the CDN, and push it there for me. Thinking that was a benefit of origin pull.

Clearly I’m misunderstanding something on how content stays in sync between CDN and non-CDN parts of the WordPress site.

Are their suggestions for keeping CDN version of wordpress content in sync with the non-CDN wordpress site?

Or is the assumption that the WordPress site is completely running on the cdn domain itself.

thanks
