I just want to host a small and very simple website on a free web host (preferably no ads). I don't anticipate heavy traffic. It's just a personal website. Just .html, .css, .swf and .air for now. No server side scripts.

But I need a mapping set for the Adobe AIR mime type. In apache you would add this line to the configuration file:-

AddType application/vnd.adobe.air-application-installer-package+zip .air

Would you be able to do this?
