Question

I’d like to make number of http requests in parallel; with either one error response or a number of them. Having done that myself a few times (with just a loop & counter), I’d like to use one that is more robust, and will handle edge cases.

Do you know if there’s a library / micro-framework out there that will do this? One, to which I can provide a number of URLs, a success callback method (for each), a single error callback; and possibly other options. This library would follow 301s, call the err-cb if any or all requests time-out or fail.

Use one of the flow-control libraries:

• Step
• Seq
• Futures
• TameJS
• Async
