Lynx

Right then, here's a question. I was under the impression that HTTP_ACCEPT was supposed to state which mime types a browser was able to deal sensibly with. So why does Lynx include various video and image mime types in its HTTP_ACCEPT? I'm a little confused by it.

Also, is anyone aware of a server side way to check whether or not a web browser is able to display CSS? And, ideally, a way to determine which flavour of CSS the web browser was able to use?

EDIT

Turns out that Lynx is being correct in its HTTP_ACCEPT - if you follow a link on a page which leads to an image, then (here at least), the default application for dealing with that file type is invoked to open it.
