You can check the HTTP headers and make an educated guess. You could for instance try http://network-tools.com, there is a tool to get HTTP headers there.

(voted to move the question to superuser.com, BTW)

There is no certain way to determine server language used by just viewing the web page.

There may be some clues like urls ending in php or jsp or asp(x). But honestly, it can be a trick.

Why would you need such a thing?
