But yet that is exactly what *is* the problem. HTTP allows headers like 
these, and it makes a difference (whether that's a good idea in the

Well, I think there is.

If compatibility to existing code (which doesn't check for null) is the 
driver here, then please consider adding a new method such as 
"isHeaderPresent(headername)".
