Using HTTP with the GCF
HTTP's ability to provide metadata with requests for service using standard verbs lets you
define a wide variety of services that a remote system can provide besides just returning
pieces of a web page. Often, though, Java ME devices need only the ability to read remote
content. You can download content using the GCF and a
ContentConnection
, as shown in
Listing 12-8.
