The URL Fetch service can be used to make HTTP and HTTPS requests of other
servers on the internet. The URLConnection
class can also
be used to do this, and in App Engine is implemented by using URL Fetch.
Chunked and hanging requests, however, are not supported. More information
is available in the
on-line
documentation.
As is typical for App Engine services, the URLFetchServiceFactory
returns a URLFetchService
, which is used to actually make requests
of the service.
