Descripción
Replaces the blog URL by another for all files under wp-content
and wp-includes
.
That way static content can be handled by a CDN by origin pull. (The origin is your blog address.)
You could upload your static files to S3, CloudFront or just any site, too.
For S3/Cloudfront, see this script
to help you with uploading/synchronizing your blog files.
This lite
version of the plugin works like the regular version but is not supported.
You can get the regular version at Github, which:
- Is free of charge, open source and without any ads.
- Supported. Here is the bug tracker if you encounter any issues.
- Has more and advanced features.
- Is updated more frequently. See Downloads.
- Quality assurance.
Instalación
- Setup your CDN: Either configure an origin pull, mirror bucket or upload your static files somewhere.
- Upload the plugin to your
/wp-content/plugins/
directory. - Activate the plugin through the 'Plugins' menu in WordPress.
- Provide the URL where your static files can be found under
Settings
.
FAQ
- How to uninstall?
-
Either deactivate the plugin or delete the plugin’s directory.
- Why another such plugin?
-
As many WP plugins don’t correctly include JS and CSS files most of the current CDN plugins cannot
rewrite links correctly. They rely on the high-level WP API.This plugin does its rewriting on the lowest level possible – PHP itself.
- How does it work?
-
After your blog pages have been rendered but before sending them to the visitor,
it will rewrite links pointing towp-content
andwp-includes
. That rewriting will simply
replace your blog URL with that you have entered in settings screen.Thus files are pulled from the other site.
- Is it compatible to plugin XY?
-
Yes, by design it is compatible to all plugins. It hooks into a PHP function (ob_start)
and there does the string replacement. Therefore, no WordPress function is altered, overwritten or modified in any way.Indeed, you could even copy this plugin’s rewriter into any arbitrary PHP software.
- Where can I see it in action?
-
On my own blog, Mark’s blog. See the source code of any page.
- Will it work with my CDN?
-
Yes, if it supports origin pull (aka mirror bucket, some sort of caching). Or if you upload your files manually.
- What about Amazon’s S3?
-
Right, S3 doesn’t support origin pull. You will have to upload your files by hand.
I’ve written a script for this, too, so it is just a matter of running it. It is linked on the bottom of my blog post about copying files to S3. - What other plugins do you recommend?
-
Now that you can offload all the files such as images, music or CSS, you should serve your blog posts as static files to decrease load on your server.
I recommend SuperCache-Plus
as it will maintain, update and create that static files from dynamic content for you.
The off-linker is compatible. - Alternatives?
-
The experts at
Arcostream
currently develop (or have it ready by now) a plugin which enables you to set up a CDN at their’s
with one click or two. Without any configuration, everything is automatic. Please google their licensed flavour of this plugin. 😉 - I discovered a bug!
-
If you are using the
lite
version, please upgrade.
The following applies only to theregular
version which you can find at Github.Share it with me! The rarer a species, the more interesting. But I will need its habitat, too.
Therefore, please send me at least one page with the plugin turned off and on, as attachment.
