How about this case:

To get to my house, click on http://maps.google.ca/maps?q=baden,on, then 
click on "Directions".

The final comma should *not* be included.  Nor should a final period, 
although of course embedded periods are typical for URLs.

Appendix E of RFC 2396 says URLs should be "quoted" or <quoted> when 
used within plaintext, and then commas should follow closing-quotes, but 
this is often not done.
