Netscape has built Enterprise Server as well as Directory Server for
users to establish their web pages using CGI (Common Gateway
Interface)/ Perl (script language) or Java. Within CGI/Perl program,
another independent functions can be spawned, which probably written
in C or C++. When the user submits his URL command, the server will
search for the remote server which enable to execute the URL command
and respond back interactively. User may fill out form and submit
again for further info. This will be all takn care of by Server's API
which was written in CGI/Perl script language (no need to compile,
they are interpreter languages, like Basic, Java).
Speaking of virus, sometimes, it is not really a virus, rather it is a
bug in CGI/Perl programs which may containing C, C++ source code.
Especailly, in C, C++, memory leak is a common problem (the reason to
cause that is that the programmer allocates a specific chunk of memory
for variable store, and forgets to free out the space, hence when it
accumulates to certain level that exceeds memory capacity, the entire
web page get hung on server site, that will probably cause your client
site get hung.)
