[Radiant] Issue with caching and radius tagging

[Sean Cribbs]

I meant primarily that if you have extensions or plugins that provide 
data to or modify the output of a page, you should be aware of the 
interactions that it will have with the cache.  For example, back in 
August when I wrote the comments behaviors, I found that a page I wanted 
to keep cached (the Commentable) would cache a redirect to itself, which 
caused an irresolvable redirect loop.  If I had run with caching off, I 
might not have noticed that.  So in a sense, I consider Radiant's 
caching to be a system feature rather than a side-effect of running in 
production. 

If Radiant used only Rails' caching mechanisms, it might be easy to 
ignore. However, even then, the cache needs to respond to the changing 
needs of the system -- you can't rule it out entirely.

I guess what I'm trying to say is write your extensions or behaviors or 
plugins with the consideration that unless you specifically set a 
page/behavior to be uncached, you will have to deal with the 
implications that come along with caching.
