What is the _afrLoop URL parameter for?
By Frank Nimphius-Oracle on Nov 15, 2010
When running ADF applications using the ADF Faces you see the _afrLoop token added to the URL looking like: _afrLoop=1039335694640519 . A frequent question in regard to this token is "can I get rid of the _afrLoop token in the URL?". The answer is no and has to do with why this token is needed. The _afrLoop param is an ADF internal parameter that is used to detect new browser windows to be opened - e.g. using ctrl+N - and also helps detecting PPR navigation. Removing this token will disable this functionality and lead to the framework to malfunction. So don't attempt removing this.
