Thank you for the contribution! It seems like request.setTimeout is not supported yet in browserify, but there's an open pull request. Do you only need this functionality in a node context?

[johanneswuerbach]

Yes, I only need it in a node context.

@ehd anything I could help to push this forward? :-)

@johanneswuerbach Sorry for not getting back before. This looks fine to me, and it should work in browsers once http-browserify supports that method.
