Can an ASIHTTPRequest be retried?

Is there a way to retry an ASIHTTPRequest? I'm using custom authentication in a REST service instead of basic HTTP authentication and I would like to retry a request if the session has expired. Calling startAsynchronous a second time on a request causes an exception. I would like to do something like this:

[request setCompletionBlock:^{
        if ([request responseStatusCode] == 500)
        {
            // try to login again in case token expired
            [server loginAndRetryRequest:request];
        } else {
            // parse response
        }
    }];

loginAndRetryRequest: will do another ASIHTTPRequest to login and when it is complete it will start the original request again from it's CompletionBlock (assuming this is possible somehow)?

It should be possible to make a copy of the request and then execute -startAsynchronous again on the copy.

Support for NSCopying protocol was added in release 1.5, which also includes automatic retry in case of timeout (selector -setNumberOfTimesToRetryOnTimeout:.

Another option could be checking their source code to see how the automatic retry is done in case of timeout, but copying and re-issuing the request should work (that was the reason to add support for NSCopying in the first place).
