It is important for application development to allow Internet communication between
Today's applications communicate using Remote Procedure Calls (RPC) between objects
like DCOM and CORBA, but HTTP was not designed for this. RPC represents a compatibility
and security problem; firewalls and proxy servers will
normally block this kind of traffic.
A better way to communicate between applications is over HTTP,
because HTTP is supported by all Internet browsers and
servers. SOAP was created to accomplish this.
SOAP provides a way to communicate between applications running on different
operating systems, with different technologies and programming
