ASIHTTPRequestErrorDomain Code=4 "The request was cancelled"

I got "Error Domain=ASIHTTPRequestErrorDomain 开发者_如何学GoCode=4 \"The request was cancelled\" exception. but I do not cancel the request.

How could it be?

By default, if a request running in a queue fails, all other requests in the queue will be cancelled.

You can disable this with:

[queue setShouldCancelAllRequestsOnFailure:NO];
