I wonder how many sites actually do "content negotiation" properly? (The proper name for that activity.)
Sites are well known to just give you their pages, and throw files at you, no matter what. Browsers are well known to say they accept */*, rather than limit the list to their known abilities. About the only differences I know of, these days, are sites that may automatically send a different version to small screen mobile devices.
e.g. You still get sent flash, even if you didn't have a plugin for it installed. The "do you want to install it?" prompts are also sent to everybody, they just don't show up if you had a Flash player installed.
It's amazing it all works as well as it does. And not surprising that there are occasional glitches.
