Re: LuaSocket - non-blocking connect ?

[gary ng <garyng2000@...>]

I use COPAS with luasocket which allows async connect. But would need a non-blocking DNS lookup if you want complete async as DNS lookup using the underlying library can be a blocking call. luasocket supports async connect if you setup the timeout to be 0 if I remember correctly.
