Server alias for virtual host does not load site

Here's my current virtual host setup for xampp:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot c:/misc/proj/usermap
ServerName usermap
ServerAlias usermap2

ErrorLog c:/misc/proj/usermap/logs/error_log
CustomLog c:/misc/proj/usermap/logs/access_log common


<Directory "c:/misc/proj/usermap">
        Options Indexes FollowSymLinks Includes ExecCGI
    AllowOverride All
        Order allow,deny
    Allow from all
</Directory> 

      

        
        
        
      

    

The site works fine with the ServerName (usermap) domain. I wanted to add another domain that specifies the same site configuration with a different domain (so I can do different things in the code based on the domain). So I added the ServerAlias ​​line.

I have the hostname for 127.0.0.1 in my hosts file:

127.0.0.1 usermap
127.0.0.1 usermap2

      

        
        
        
      

    

The site works fine if I use the original usermap domain, but the browser keeps loading if I try to use usermap2. It shows a blank page and "sending a request to usermap2 ..." is in the status bar, but nothing else happens. Is there a log file that I could check to see why it isn't working? Apache / logs show nothing.
