[1.4] [Proposal] Global proxy configuration

[Andreas Hartmann]

Hi Lenya devs,

I propose to introduce the option to configure global proxies
(i.e., proxies for all resources outside a publication) independently
of publications.

I have implemented a GlobalProxies service in my sandbox:

  <component logger="lenya.proxy"
    role="org.apache.lenya.cms.linking.GlobalProxies"
    class="org.apache.lenya.cms.linking.impl.GlobalProxiesImpl">

    <proxy ssl="false" url="http://cms.example.com"/>
    <proxy ssl="true" url="https://cms.example.com"/>

  </component>

which is used by the OutgoingLinkRewriter (and thus by the
ProxyTransformer and ProxyModule):

  // link doesn't point to publication
  else {
      Proxy proxy = getGlobalProxies().getProxy(ssl);
      rewrittenUrl = proxy.getUrl() + url;
  }

The <proxies> element in publication.xml will become obsolete,
only the area-based <proxy> elements will be necessary.


In contrast to the current implementation, requests to non-publication
URLs can now use the proxy settings. An example is the CSS page

  /lenya/css/boxes.css

which can now build proxy-based URLs like this:

  url('https://cms.example.com/modules/svg/tab-topRight...')


WDYT about this concept?
The easiest way would be to configure the proxies in cocoon.xconf,
but we could also use a separate configuration file.

+1 ... I like this idea a lot, although I'm sure I don't grasp all the
implications.

Are there no objections?

Thorsten, since you introduced the root proxy concept, what do you
think about the global proxy configuration?

Should I attach a patch to Bugzilla so you can try it out?

No, just go ahead and add it.

+1

Sorry for not giving word earlier, just got back to work after having my
parents at home and hardly read all mails.
