Subject Re: [users@httpd] Multiple Instances of Apache
Date Fri, 18 Jan 2008 16:36:55 GMT
Thank you Kris for a quick reply.

However, if my other apache's are dependant on a master apache (which has
it's own app running) and was the cause of failure at time because of which
I want other instances, then I am still dependant on the master
(troublesome) one - right?

Also, if master was http://mysite.com

and second was http://mysecondsite.com:8080

How can I still access second one as http://mysecondsite.com/ - this can be
configured in apache (to skip the port)?

Or will this be done at DNS level?

Or can this be done at all?

Thanks,
Mandy.
