Package com.google.appengine.api.urlfetch Description

Provides a service to make HTTP/S 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.

As is typical for App Engine services, the URLFetchServiceFactory returns a URLFetchService, which is used to actually make requests of the service.
