The I/O reactor works with abstract SocketAddress-es. HttpCore makes no assumption whether a particular SocketAddress represents a DNS host name or an IP address. The process of DNS name resolution is out of HttpCore scope. In practical terms that does mean the I/O thread can be blocked while a specific DNS name is being resolved. As this problem cannot be solved without an external dependency, I am personally prepared to live with this limitation.
This is a bit tricky. It would be good to have an interface that does the lookup asynchronous. I do something like that in my proxy to spawn a worker thread that does the lookup. DNS timeouts can easily be 2 minutes, handling many connections with that may be acceptable for a simple client, but can easily be very bad if you want to build a web spider or a web proxy or ... Sam: I use the dnsjava package to do dns lookups in rabbit. It is a dns library in pure java. Internally it uses some parts of nio, but the interfaces it provides are blocking calls. I would like to have time to fix dnsjava to provide an asynchronous interface, but as it is now I do not have the time. http://www.xbill.org/dnsjava/
Absolutely. I/O operations over NHttpConnections can be executed in full duplex.
Glad to hear that. /robo --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
