One problem with the first proposal is that you don't know the mimetype of the content before you load it. Just because it ends in .gif does not mean it is a gif file (eg, using GD a .php file could be a GIF image). <br>
<br>Instead of using class, maybe the rel attribute would fit better. <br><br>Marius Gundersen<br><br><div class="gmail_quote">On Mon, Nov 9, 2009 at 8:43 PM, Fabian Freiburg <span dir="ltr"><<a href="mailto:f.freiburg@googlemail.com">f.freiburg@googlemail.com</a>></span> wrote:<br>

PROPOSAL<br>
The "base" element is very helpful. Trouble is that it affects all
relative links and "src" attributes. Especially for the "src"
attributes it would be very useful if it could define a context or
media type to which it belongs. With this it would be possible to
define a "base" URI fore. g. images, javascripts or stylesheets.
Furthermore it would be very easy to use a CDN for serving static media
files. There are probably some more advantages.<br>
<br>
There are different ways to implement this feature: One idea is to use
a "content" or "type" attribute, where the MIME type to which the
"base" belongs can be defined. For example the following "base" would
affect all GIF images:<br>
<base href="<a href="http://example.com/media/images/" target="_blank">http://example.com/media/images/</a>" type="image/gif"><br>
<br>
Another idea is to use some kind of tagging, which would mean more flexibility. For example:<br>
<base href="<a href="http://example.com/media/images/" target="_blank">http://example.com/media/images/</a>" class="images cdn gif"><br>
Each element using one of the classes will belong to the relevant "base" element.<br>
<br>
Please let me know what you think about it.<br>
