Whats used to run this site ?

Hi

I see that this site is following a Web 2.0 style plus a lot of AJAX.
But what server-side language is used to run this site ? Java / PHP / Python / RoR / ASP .NET / Perl / CFM ?
My guess : RoR

Anjanesh—only two parts of this site run on Ruby on Rails:

1. Small World
2. Cleartrip Forum

We weren’t too happy with Ruby or RoR’s execution speed and, so, we don’t run our main searches with it. I’m sure we could have managed to scale Rails, but that still wouldn’t have given us the critical speed required by our main search.
