Hi, Are there any plans for Apache to support "Feature negotiation" as specified in RFC 2295 (see http://www.ietf.org/rfc/rfc2295 )?
FYI the back story to this request is from a discussion on the webkit-dev mailing list regarding having images served to a client dependant on its resolution and/or viewport width. Normal browsers may get an the image as 600px across, small screen devices may get an image that is 150px across and browser requesting the image for printing purposes may get an image that is 1200px across. The idea would be to able to create a type-map file for the images like or similar to the following: URI: image URI: image-1200x1000.jpg Content-feature: width=1200; qs=0.9 Content-feature: height=1000; qs=0.9 URI: image-600x500.jpg Content-feature: width=600; qs=1.0 Content-feature: height=500; qs=1.0 URI: image-300x250.jpg Content-feature: width=300; qs=0.6 Content-feature: height=250; qs=0.6 URI: image-150x125.jpg Content-feature: width=150; qs=0.3 Content-feature: height=125; qs=0.3 And have Apache perform server side selection to pick the variant dependant of the "Accept-Features" portion of the request. e.g. a browser on a small display would send "Accept-Features: width=[100-250], height=[100,200], *" and image-150x125.jpg would be selected by Apache. BTW if you are wondering why the image-1200x1000.jpg has a lower qs than image-600x500.jpg, this is so that in the default scenario (no Accept-Features sent) the smaller image is sent and the larger bandwidth consuming image is only sent when specifically requested (e.g. for printing).
