[web2py] Differentiating between URLs in web2py controllers

[Saurabh Kumar]

Hi,

I am writing a web2py application wherein I want my controller to behave 
differently to following URLs

/user/login

/user/login#_=_

Please suggest a way to differentiate between these two.   Would it ask for 
make a modification in routes.py?

Thanks

Saurabh
