Subject Re: NIO Connector, please review
Date Thu, 22 Jun 2006 01:07:50 GMT
Ok, I have a non SSL enabled Java NIO connector created and checked in. 
It works in the exact way as APR, meaning it blocks on read and write,
So its no true NIO, but close enough to handle comet style traffic, and 
to increase the connection count without increasing thread count.
