CDN support for Plone
Table of Contents
This package implements a very basic CDN support for Plone sites. Resources registered at the portal registries (Styles, Scripts and KSS) can be delivered by specialized servers on different hostnames.
Also this package implements an experimental approach to serving image content from a CDN. We plan to improve this feature in future releases.
You must add a provider package in order to use CDN Support!
Available provider packages are:
- AlternateHostname - collective.cdn.alternatehostname
- Coral Networks - collective.cdn.coral
- MultipleHostnames - collective.cdn.multiplehostnames
To enable this product,on a buildout based installation:
Edit your buildout.cfg and add collective.cdn.core to the list of eggs to install[buildout] ... eggs = collective.cdn.core
If another package depends on the collective.cdn.core egg or includes its zcml directly you do not need to specify anything in the buildout configuration: buildout will detect this automatically.
After updating the configuration you need to run the ‘’bin/buildout’’, which will take care of updating your system.
Go to the ‘Site Setup’ page in the Plone interface and click on the ‘Add/Remove Products’ link.
Choose the product (check its checkbox) and click the ‘Install’ button.
Uninstall – This can be done from the same management screen, but only if you installed it from the quick installer.
Note: You may have to empty your browser cache and save your resource registries in order to see the effects of the product installation.
After installing this package, go to the ‘Site Setup’ page in the Plone interface and click on the ‘CDN Configuration’ link.
In this page you can choose which registries will use the CDN settings by clicking the respective checkboxes.
Also you must choose a provider – added by specific packages as collective.cdn.coral – and then inform hostnames, port and a path to be used by the provider.
The simplest configuration would be possible by installing the collective.cdn.alternatehostname, which will enable you to add a alias hostname to your site.
This configuration allows you to add a alternate hostname as your CDN, for example, using the alias localhost for a site running on 127.0.0.1.
Serving images from CDN still is considered a experimental feature as it only supports images which are referenced through the tag method of the Archetypes ImageField. We plan to support other content types in the future.
