Chris,

1. If you are running rails 2.1 && memcached then you can do this in  
fragment caching:

\<% cache(key, :expires\_in =\> 5.minutes) do %\>  
hello, world!  
\<% end %\>

Yes, though memcached is the only mechanism it is already built-in.  
There is  
a way that works with the other three mechanisms (I think, I’ve only  
tried it  
with memory\_store). If anyone is interested, I’ll post it on my blog.
