public class ContextConnection
extends URLConnection

The ContextConnection extends the java.net.URLConnection to provide access to a resource which is available from LaunchpadContentProvider provided to Sling.

This class is implemented by actually connecting to a resource URL which is provided by the resource provider and delegating the relevant method calls. Currently only getContentLength(), getContentType(), getInputStream() and getLastModified() are supported.
