Examples of BackoffLimitedRetryHandler

org.jclouds.http.handlers.BackoffLimitedRetryHandler
Allow replayable request to be retried a limited number of times, and impose an exponential back-off delay before returning.
The back-off delay grows rapidly according to the formula 50 * ( {@link TransformingHttpCommand#getFailureCount()} ^ 2). For example:

Number of Attempts Delay in milliseconds

1 50

2 200

3 450

4 800

5 1250

This implementation has two side-effects. It increments the command's failure count with {@link TransformingHttpCommand#incrementFailureCount()}, because this failure count value is used to determine how many times the command has already been tried. It also closes the response's content input stream to ensure connections are cleaned up. @author James Murty

Number of Attempts	Delay in milliseconds
1	50
2	200
3	450
4	800
5	1250
