HTTPClient
Class RetryModule  

java.lang.Object
  HTTPClient.RetryModule

All Implemented Interfaces:

GlobalConstants, HTTPClientModule, HTTPClientModuleConstants

---

class RetryModule

extends java.lang.Object

implements HTTPClientModule, GlobalConstants

This module handles request retries when a connection closes prematurely. It is triggered by the RetryException thrown by the StreamDemultiplexor.

This module is somewhat unique in that it doesn't strictly limit itself to the HTTPClientModule interface and its return values. That is, it sends request directly using the HTTPConnection.sendRequest() method. This is necessary because this module will not only resend its request but it also resend all other requests in the chain. Also, it rethrows the RetryException in Phase1 to restart the processing of the modules.

Since:

V0.3

Version:

0.3-2 18/06/1999
