There's another issue in the indirection that scares me and that's the  
fact that having a URL contain another URL (speaking colloquially  
here, you know what I mean:-) potentially opens up a whole can of  
worms similar to cross-site scripting in HTML documents. Applications  
that are unaware of the indirection could inadvertently allow access  
to content across firewalls, etc.
