Overview

This package provides support for an alternate hostname CDN config for Plone sites.

This provider allows you to designate an alternate hostname to serve skin resources for your portal.

A very basic example would be to add 127.0.0.1 as an alternate hostname – using same port number as your zope instance – during development, thus enabling resources to be downloaded from 127.0.0.1 while content will be served from localhost.

Requirements

• Plone 3.3.x (http://plone.org/products/plone)

• Plone 4.0.x (http://plone.org/products/plone)

• collective.cdn.core (http://pypi.python.org/pypi/collective.cdn.core)

Installation

To enable this product,on a buildout based installation:

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

   [buildout]
   ...
   eggs =
       collective.cdn.alternatehostname

If another package depends on the collective.cdn.alternatehostname 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.

Advanced Usage

Using a different path offers you the possibility of creating a simple caching/cdn server for multiple sites. As an example we will consider we have two Plone sites, www.simplesconsultoria.com.br and www.simplesnet.com.br, and we setup cache.simples.srv.br as an alternate hostname in both Plone sites.

In order to differentiate one site from the other we will set different paths in each of them:

• simples in www.simplesconsultoria.com.br

• simplesnet in www.simplesnet.com.br

So each site will have the following settings:

• www.simplesconsultoria.com.br

  • Provider: AlternateHostname

  • Hostname: cache.simples.srv.br

  • Port: 80

  • Path: simples

• www.simplesnet.com.br

  • Provider: AlternateHostname

  • Hostname: cache.simples.srv.br

  • Port: 80

  • Path: simplesnet

And a link to a file portal_css/beyondskins_simples/simplesconsultoria_site-cachekey0549.css, would return for www.simplesconsultoria.com.br:

http://cache.simples.srv.br/simples/portal_css/beyondskins_simples/simplesconsultoria_site-cachekey0549.css

And for www.simplesnet.com.br:

http://cache.simples.srv.br/simplesnet/portal_css/beyondskins_simples/simplesconsultoria_site-cachekey0549.css

So, our frontend server must rewrite calls to simples/ to www.simplesconsultoria.com.br server and calls to simplesnet/ to the www.simplesnet.com.br server.
