Method	Description
Add ( Uri uri ) : void	Add a URI to be requested to the queue.
Dispose ( ) : void
Start ( System.TimeSpan uploadInterval, IEnumerable previouslyUnrequested = null ) : void	Start the BackgroundHttpRequester with a given upload interval and a list of previously unrequested URIs.
StopAsync ( ) : Task>	Stop the BackgroundHttpRequester and return a list of URIs that were not requested.

Method	Description
GetInnermostException ( Exception ex ) : Exception	Obtain the innermost Exception from within an Exception.
RequestWithFailureRetry ( Uri requestUri, CancellationToken cancellationToken ) : void	Request the URI retrying as appropriate if a failure occurs.
WaitBetweenFailedRequests ( System.TimeSpan &previousRetryDelay ) : void	Delay for a period of time between failed network requests.

Method	Description
Dispose ( bool isDisposing ) : void
GetNextQueueEntry ( Uri &entry ) : bool	Get the next entry from the queue.
RequestLoop ( ) : void	Loop that keeps requesting URIs in the queue until there are none left, then sleeps.
ShouldUsePostForRequest ( Uri requestUri ) : bool	Whether a URI request is too long to be sent as a GET and instead the query parameters should be sent as the body of a POST instead.
