Coral CDN support for Plone

Project description

CDN Support for Plone: Coral Networks


This package provides Coral Networks CDN for Plone.

CoralCDN is a decentralized, self-organizing, peer-to-peer web-content distribution network. CoralCDN leverages the aggregate bandwidth of volunteers running the software to absorb and dissipate most of the traffic for web sites using the system. In so doing, CoralCDN replicates content in proportion to the content’s popularity, regardless of the publisher’s resources.[#]_


To enable this product,on a buildout based installation:

  1. Edit your buildout.cfg and add collective.cdn.coral to the list of eggs to install

    eggs =

If another package depends on the collective.cdn.coral 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 CDN Support for Plone (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.


CDN settings

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.

Then choose the CoralCDN provider and save the settings.

How it works

From now on all choosen resource registries will generate links pointing to <site_url><path_to_resource>, thus using the Coral Networks infrastructure to delivery those files.

For example, the link to simplesconsultoria_site-cachekey0549.css file would change from:
