Pulling My Hair Out With WEBrick!

WEBrick and I are not getting along tonight.  I'll throw out some  
general questions here in a shameless attempt to beg help from people  
smarter than me:

1.  If I have a proc handler dealing with some events and I have a  
FileHandler serving static content and I decide halfway through my  
proc I want to hand off to the FileHandler, is there an easy way to  
accomplish that (without using HTML redirects).

2.  My proc looks for complex paths and builds content based on them,  
I would rather show the player simple urls that mean the same thing  
though.  Is this possible?  Put another way, if a request comes in  
for /view/prototype/house.rhtml can I set the url of the response to / 
house.rhtml in some way the browser would show it as this?

3.  My main reason for asking the last question is handling relative  
image loads.  Is there some way to handle relative paths in the  
response?

4.  I've tried configurations without a FileHandler and I didn't even  
pass a :DocumentRoot to the constructor, I then installed my own file  
handling proc at "/".  My proc does handle at least some of the  
requests; however, it seems that it is not called for all of them.   
For example, if the proc loads index.html and that page includes an  
image, the GET request seems to bypass my proc.  Why?  What is  
serving that image?

Thanks in advance for any tips you can pass along.
