Perhaps a good discussion from here would entail which technologies have
these features.. or how to obtain these features with different
technologies.  For instance, we've already heard about
apache+struts+jboss+etc. etc....  Yes, Walmart, Ebay and others use
Java.  There are some pretty large companies using perl too.  What do
those companies use for transaction management etc.  PHP, Python, Ruby? 
How do you cluster sessions with Rails, or does it have it?  Are there
certain things certain languages/platforms just can't do yet?

I think this would be valuable information from those that know.
