Apache Virtual Host URL

I made an Apache virtual host for a web application that works fine, but I have a problem with the URL. I want my application to be accessed only using an url similar with: http://ip_address/app_name, but now the aplication can be access also with http://ip_address/.

My virtual host looks like this:

NameVirtualHost 192.168.5.235:80

<VirtualHost 192.168.5.235:80>
  ServerName 192.168.5.235
  Alias /ksw "/home/ksw/site"
  DocumentRoot "/home/ksw/site/"
  ErrorLog /home/ksw/logs/error_log
  CustomLog /home/ksw/logs/access_log combined
</VirtualHost>

Is there a way to configure my application to be accessed only using http://ip_adress/app_name? Thanks.

The home /home/ksw/site files are:

Captain Obvious says it shouldn't be so. =)
May be only if 'app_name' dir is a symbolic link to 'ip_addr' dir.
Or if you use django (for example) and configured views incorrectly.
Do you use php? If so - something definitely wrong happens=)

added:
If you 'app_name' string is actually 'ksw' than...
You've installed you mediawiki in the site root dir and ONLY added a link by 'Alias /ksw' to it!!
Solutions:

• If you want ONLY to restrict access to http://ip_address/ use .htaccess apache file.
• If you want 2 different pages at / and /app_name you need to create folder 'app_name' and install your app there!

That's all.
