Thanks, I'll make sure the "params" object gets documented also. Currently, there is not so much you can set per HTTP request. You can basically add HTTP headers and you can also add tags that lets you single out specific results based on those tags (e.g. when using thresholds or when plotting graphs of results).

So - HTTP request timeouts can not be changed at the moment, but this is something I think would be very simple to implement. If you open an issue about it I'll see what we can do to get it implemented quickly.
