Similar things have certainly been done, but I'm not aware of it being published. For example, three years ago I wrote a set of modules to transform images on-the-fly to match a client's capabilities, for a manufacturer of small-screen (mobile phone) browsers who wanted to use a proxy to reduce the volume of traffic sent. > I was able to create a type-map file for the images as follows: > > [chop] > > Apache would (correctly) perform server side selection to pick the > variant with the highest qs, however I could not find any way of > specifying features (such as DPI) for each variant, that would allow a > lower qs variant to be selected based on a appropriate request with > "Accept-Features" (e.g. "Accept-Features: dpi=[70-100]"). Sounds sufficiently close to the existing mod_negotiation that it might be implemented as an enhancement to that. -- Nick Kew Application Development with Apache - the Apache Modules Book http://www.apachetutor.org/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
