Over at blogger I have a post on the alternative file extensions HTM and HTML.
As HTML5 becomes HTML there seems to me to be a case for webmasters and web application servers to have a choice in file extensions – at least for entry points such as
· www.example.com/
and for sub-domain root URL’s such as
· proposals.example.com/
such that .htm will be selected for Mobile and .html for Large format devices.
This will be of no help in the PHP world of index.php without redirection and likely an additional option in HTTP headers and another authorized meta value for HTML5 content.
At the moment, Apache servers can be configured with an ordered-list such as
· index.htm index.html index.php
but there is no flag to set for mobile versus other as there is no field in HTTP requests for the likes of screen size at w3.org or propsed by the HTML Working Group to my knowledge.
Now to visit WHATWG.
We may well ignore or forget default.htm and home.htm by 2014 … or 2020.
