My browser (Firefox 3.5) does not send browser width-at-the-time information in the request headers. I doubt any browsers do, so you can't use this in any sort of routes or respond_to shinanagins. If you need your application to perform differently depending on different user agents, you need to relay on the User-Agent header. This will of course require some research to find the UA's that your app needs to consider as mobile devices, and be ready to respond to user feedback when someone browses with a UA you did not anticipate. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
