Hi,

I often come across some nice web sites and I want to know what technologies (PHP, JSP, ASP.NET, etc) are used to build those web sites.

The web address of some web sites end with ".aspx", ".php", ".jsp", etc. But some web address do not contains any indicators.

Is there any systematic way we can use to know the technologies used by a web site?

Thanks.
