    Can someone tell me how one can determine of a site is running PHP or ASP?
    I can determine if it has .php or .asp, but some cases these are hidden.

    You can tell, most times, if you look at the HTTP response headers. For example my fourshapes domain shows this:

    Server: Apache/1.3.34 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.4.2 FrontPage/5.0.2.2635 mod_ssl/2.8.25 OpenSSL/0.9.7a

    and has the extra header:

    X-Powered-By: PHP/4.4.2

    Also my online banking account has: Server: Microsoft-IIS/5.0

    So it's most likely going to be asp or .net
