Hi Chandrasekhar,

basically the "S" of HTTPS adds security and optional authentication mechanisms to the HTTP protocol if needed. The security mechanisms are based on certificates but perhaps you want to take a look into Wikipedia to get more information.

HTTPS is often called SSL, altho more properly, its TLS

There are many protocols you can use, FTP, NNTP, etc.

Most folks ask the question the other direction: My boss wants me to use protocl X, how do I do that?

Many HTTP servers support HTTPS, too, so often you can use HTTPS instead of HTTP. There are no other protocols that you can use instead of HTTP.

Plenty of other protocols are available for different purposes, though, but you'd need different client and server software to use them.

@ulf is right, if you restrict yourself to servlets. But Java can implement any protocol you want, including all the standard ones, and stuff you invent yourself.

But its a lot easier to use code that others have written, debugged and documented. So servlets over HTTP (or https) is the easiest way to go
