title: X-Runtime header related attacks
body: <p>There are various http header fields which provides some clue to the attacker. I wanted to understand that the header field 'X-Runtime', if present in the response header, will it give any clue to attacker? I read some where that the field can be used for DOS attacks but it is not clear as to how the same can be used for DOS attacks. It would be great if I get a clue in this forum. </p>
