Timeout in httpRequest

[mattbrain]

I came across a minor bug when using this on a relatively low powered RPi. When discovering a service of which there were many instances, the http.request was throwing a timeout and ultimately crashing as the server (which was hosting all these services) failed to respond quickly enough.

To overcome it I increased the timeout in req.setTimeout by a factor of 10, but i'm sure there is a more elegant way of handling this situation.
