What is the _afrLoop URL parameter for?

Frank Nimphius
Master Principal Product Manager

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.
