I am brand new to URL rewriting. I am using an Apache rewriting module on IIS 7.5 (I think). Either way, I am able to do rewrites successfully, but am having trouble on a few key things.

I want this pretty url to rewrite to the this ugly url:

mydomain.com/bike/1234 (pretty) 
mydomain.com/index.cfm?Section=Bike&BikeID=1234 (ugly)

This works great with this rule:

RewriteRule ^bike/([0-9]+)$ /index.cfm?Section=Bike&BikeID$1

Issue #1

I want to be able to add a description and have it go to exactly the same place, so that the useful info is completely ignored by my application.

mydomain.com/bike/1234/a-really-great-bike (pretty and useful)
mydomain.com/index.cfm?Section=Bike&BikeID=1234

Issue #2

I need to be able to add a second or third parameter and value to the url to get extra info for the db, like this:

mydomain.com/bike/1234/5678
mydomain.com/index.cfm?Section=Bike&BikeID=1234&FeatureID=5678

This works using this rule:

RewriteRule ^bike/([0-9]+)/([0-9]+)$ /index.cfm?Section=Bike&BikeID=$1&FeatureID=$2

Again, I need to add some extra info, like in the first example:

mydomain.com/bike/1234/5678/a-really-great-bike (pretty and useful)
mydomain.com/index.cfm?Section=Bike&BikeID=1234&FeatureID=5678

So, how can I combine these rules so that I can have one or two or three parameters and any of the "useful words" are completely ignored?
