in reply to Don't reprint header

I really don't know which program may have already printed a header. This is something I have to figure out for myself. Isn't there a way to get this information from the server? Or cashed somewhere in the browser (the calling programs would be in the same browser session)?

    You are the server. Something in your framework may track it for you, but you didn't mention any of the components.

    There's no way to ask the browser if you told it or not. There's no way to observe the browser for the effects of having told it.
