Hi everyone,

I need to write a web app, that will support millions of user accounts,
template-based user pages and files upload. The client is going to be
written in Flash. I wondered if I coudl get your opinions - what do you
think is the best language to use for the server? Python or Java? And
I'm talking scalability, object oriented, development tools etc.

Thansk for any idea! I'd love to hear it
Happy New 2006,
Lior
