concurrent servers

[Jonathan Vanasco <mo...@2xlp.com>]

I've switched my port80 proxy / vanilla server to nginx.  it's a  
great little server out of russia.

It happens to feature a rather neat thing as well...
	when you upgrade the binary , you can have it start up a new binary,  
bind to 80 ( along with the existing one ) , then have the old binary  
shut down
	the effect is a seamless upgrade with no downtime

	see: http://wiki.codemongers.com/NginxCommandLine  and the section  
"Upgrading To a New Binary On The Fly"

is there any way to do that with apache2/mp2 ?

apache doesn't seem to like to bind to any port that something else  
is running on.  i couldn't find an override anywhere.
