add file endings generating more file formats+discussion

What to do with endings like .php and .asp? To maintain canonical URLs from migrating sites we'd want to treat them like .html - are there use cases where that would not make sense? http://www.fileinfo.com/filetypes/web lists includes more of these.

There are a bunch of directories of file endings. None of the ones I found with a quick search looked that great (e.g. none of them pointed to published specifications for .rtf), but http://filext.com/ has >10,000, and http://www.fileinfo.com/ has a nice list of categories to browse through.
