httpd 2.2.10 mod_proxy bug?

[David Multer <david@xxxxxxxxxx>]

I just installed the latest 2.2.10 version of Apache web server and  
noticed it's broken my Tomcat+Hudson setup. I've confirmed that  
falling back to 2.2.9 eliminates the problem. I suppose it could be an  
issue in my config that was only uncovered with the latest version,  
but for now I'll assume it's a real problem.

My httpd.conf:
...
LoadModule proxy_module modules/mod_proxy.so
...
ProxyRequests off
...
ProxyPass /hudson/ http://subdomain.domain.com:8080/hudson/
ProxyPassReverse /hudson/ http://subdomain.domain.com:8080/hudson/

Using 2.2.10, when I navigate to http://subdomain.domain.com:8080/hudson/ 
 everything works fine. So Tomcat+Hudson is good. When I go to http://subdomain.domain.com/hudson/ 
 I get a 502 GET /hudson/ error reporting a DNS failure for  
subdomain.domain.com. Again, both approaches work fine under 2.2.9.

Here's what shows up in my Apache error log:
[Tue Nov 04 16:04:55 2008] [error] [client X.X.X.X] proxy: DNS lookup  
failure for: subdomain.domain.com returned by /hudson/

Thanks for any help. I wanted to ask before filing a bug report.
