You can easily host static web content (.html, .css, .js, etc), if that's what your asking about. All you have to do is drop your web files in an application folder under the "appserver" "static" folder, for example:
$SPLUNK_HOME/etc/apps/<YOUR_APP>/appserver/static/<my_page.html>
You can then access that file via HTTP at the following location:
http://<YOUR_SPLUNK_SERVER>:8000/en-US/static/app/<YOUR_APP>/<my_page.html>;
I would suggest creating a custom app for this kind of stuff, even if it only contains a few few files. Creating a new "app" isn't a very difficult process. (Of course, you could simply host this file in an existing app, but then you run the risk of your stuff being overwritten during an upgrade.)
