It is initiated at the server side, but requires an extra round trip HTTP
transaction with the client. The overall flow goes like this:
* Client makes the original request
* Server reads the request, decides which
servlet or JSP page should create this
response, and sends back a "redirect"
response telling the client to call that
servlet or page directly
* Client automatically follows the "redirect"
* Server sends back the actual response
Request forwarding is more like a "go to" on the server side:
* Client makes the original request
* Server reads the request, decides which
servlet or JSP page should create this
response, and then calls it to create
the actual response
If the client is at the far end of a slow modem, the time difference between these
approaches can be substantial.
