Check HTTP header size

This looks like a good idea but where did you come up with the number 200,000? I have doubts about that number.

In fact, while it seems there is a limit on the size of the request header, it's not clear to me that there is any such restriction on response headers. Even if there is, it seems the restriction should be on the cumulative size of all headers, not just one of them.

I´ve just posted a pull request with the solution for this problem. If the header exceeds 8k the user will reveive an error message from ChromePHP on the log, instead of an 500 Interval server error.
