> 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?
