          throws java.io.IOException,
                 org.apache.http.client.ClientProtocolException

Executes a request using the default context and processes the response using the given response handler. The content entity associated with the response is fully consumed and the underlying connection is released back to the connection manager automatically in all cases relieving individual ResponseHandlers from having to manage resource deallocation internally.

Specified by:

execute in interface org.apache.http.client.HttpClient

Parameters:

request - the request to execute

responseHandler - the response handler

Returns:

the response object as generated by the response handler.

Throws:

java.io.IOException - in case of a problem or the connection was aborted

org.apache.http.client.ClientProtocolException - in case of an http protocol error
