}}

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

    	if slength := r.HTTPRequest.Header.Get("Content-Length"); slength != "" {
    		length, _ := strconv.ParseInt(slength, 10, 64)

    		length = 0

    		r.BodyStart, _ = body.Seek(0, 1)

    		body.Seek(r.BodyStart, 0)
    		length = end - r.BodyStart

    	}
    
    	r.HTTPRequest.ContentLength = length
    	r.HTTPRequest.Header.Set("Content-Length", fmt.Sprintf("%d", length))
    }}

      BuildContentLength 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.

            ValidateEndpointHandler is a request handler to validate a request had the appropriate Region and Endpoint set. Will set r.Error if the endpoint or region is not valid.

            		}
            	}

              ValidateParameters is a request handler to validate the input parameters. Validating parameters only has meaning if done prior to the request being sent.
