Trying to do this on the HTTP level seems too difficult. It is important as a developer to not get hung up on a specific solution. The problem is you want to do a series of checks before you handle the upload. All you need to do is put a qualifying page before the upload. This qualifying page will only show them the upload form if they pass the series of checks and qualify. That is exactly what you are trying to do only you can do it in code PHP. If it is possible, the HTTP 100 thing will always require lots of additional configuration, thus creating a headache for support later on. If you do it in the code those that come behind you (or yourself in a couple of years) will be able to clearly understand what the app is doing.
