How to set a timeout for getInfo request?

Hi, i'm requesting the video info over proxy and some proxies take a lot of time (more than 30s) to finish the request.

Is there a simple way to set the max. time taken for a get info request, so that i can start again with another proxy? I already tried to set "timeout" in the request options but it seems to not have any affect.

Or is there any way to destroy the actual request so that i can set an own timer?

I already googled a lot for setting timeouts for requests over proxy but haven't found a working solution. Maybe someown got it already to work?
