Adding connectTimeout setting

[mattiash]

I want to use axios to connect to an http-server that is available via several different servers with different url:s. If one of the servers does not respond, I want to try another server instead. To get fast failovers, I want to set a low timeout for the request.

But the server sometimes takes a long time to respond (when I am making a complex query). To give the server time to generate the response, I have to set a high timeout.

What I really want to do is set a low connectTimeout, so that if the server has not accepted the tcp connection within this timeout, the request is aborted, but a high timeout to give the server time to generate the response.

Resolves #1739

I got a issue with the low response. and i fix it by another way. i dont think this is a good way for fix this problem. because the node event loop system will block some timer at sometime. and error will happend.

Hi,

Thank you for this pull request, however it seem that it has gone stale and is either far out of date with the current master head or has unresolved review issues. Should you feel that this pull request is still relevant please submit a new pull request.

Thanks

It would be so great to have this on master, the code seems really great and the feature is really missing on axios !

I noticed the same behavior, I was testing timeout trying to reach an unexisting host and just noticed that Axios just keep the connection open till the end of timeout when it should just fail because network fails.
