}}

    AfterRetryHandler performs final checks to determine if the request should be retried and how long to delay.

    	} else {
    		r.HTTPRequest.ContentLength = 0
    		r.HTTPRequest.Header.Del("Content-Length")
    	}
    }}

      BuildContentLengthHandler builds the content length of a request based on the body, or will use the HTTPRequest.Header's "Content-Length" if defined. If unable to determine request body length and no "Content-Length" was specified it will panic.

      The Content-Length will only be aded to the request if the length of the body is greater than 0. If the body is empty or the current `Content-Length` header is <= 0, the header will also be stripped.
