Hi, Herman,
I found your idea very cool, so I started working on something
similar. I used the following URL pattern to match file names:
'/(\w+.\w{3})'
Of course, it's not a very comprehensive regex, but as a proof of
concept, it's good enough. The filename gets handled properly, so I
can:
class resizer:
def GET(self, filename):
return filename
Hope that helps. Also, if you're really stuck, and don't have much
time, I'd recommend using a debugger like WinPDB to go through your
code and figure out what web.py thinks about those URLs.
