> It would be really helpful if we'd had a method to specify a timeout or at
> least that a good timeout value is preset as default. (like 1 minute for
> instance)
> Tbh I am rather unsure if that can be fixed in Camel directly or if Ivy
> should be fixed. IMO before accessing a URI Ivy's BasicURLHandler should use
> the isReachable(url, timeout) to test if it makes sense at all to connect
> instead of using getURLInfo right away?
