Subject Re: Fed up to the back teeth with tomcat !!!
Date Fri, 13 Apr 2001 00:10:19 GMT
I ran into this already myself. I was using the ServerName and ServerAlias
directives in Apache:

ServerName host.com
ServerAlias www.host.com

But my Host directive in server.xml was just for host.com. So, any request
to www.host.com caused the CPU-bound loop. I posted a few days ago asking if
wildcard or multiple host name capability was in the future for the Host
directive, like:

<Host *.host.com>
OR
<Host host.com www.host.com>

In my case, I don't want to use two Host directives, because that causes all
of my servlets to be instantiated twice -- once per host. Does anybody know
if pattern matching or multiple host capability will be added to the Host
directive in the future? I'd really like people to be able to pull up my
domain with or without the "www.", without re-initializing my servlets.

Thanks,
--jeff
