[Radiant] Multiple radiant sites and tags

[Bobby Calderwood]

Hello,

To all those who've contributed: Thanks for Radiant!  I have been  
personally using it for about 7 months, and have loved it.  I was  
asked to revamp my company's website(s), and after an exhausting  
journey through many other CMS's, I returned to Radiant, and my boss  
and I couldn't be happier.  Bravo!

My company has a bunch of sites, and because most of my colleagues who  
will be generating content are non-technical, it would be nice to host  
them all using one radiant install and admin page.  I am using radiant  
to host multiple sites as described inhttp://wiki.radiantcms.org/How_To_Host_Multiple_Websites_by_using_mod_proxy 
.

I've noticed, however, that many of the tags break when using one  
install to host multiple sites.  Specifically I've found that <r:link / 
 > and <r:url /> generate URLs relative to the Radiant root.  I  
imagine that every tag that deals with a URL would be affected by this.

Is there a built-in way to get these tags to generate URLs relative to  
some other node in the hierarchy?  Or should I dive into the code and  
hack something together?  I saw allusions to this type of  
functionality in a previous message to this list:

http://www.nabble.com/r:link-and-hosting-multiple-sites-off-a-single-radiant-instance-td8567322.html#a8567322

I am using Apache 2.2 as a balancer in front of a pack of mongrels,  
for the main (top level) site, and pointing 2nd level sites to their  
respective nodes using mod_proxy, if that matters.

Any help with this would be much appreciated.

Cheers,
Bobby Calderwood
