Thanks, all.. This has greatly solved many problems for me.

However, I've notice that the server console is spitting out this 
message below with every request hit that comes in:

warning: nested repeat operator + and ? was replaced with '*': 
/\A((?:\d+)?(?:\.\d+)?)\s*([a-z]{1,2}\d+)\z/

The whole process works fine, and but I am confused as to what this 
means.

Also, one more question... what does that "i" mean at the very end of 
the regex pattern?  "/...../i =! str"

Is that what tells it to dump the results into the $1 and $2 variables?
