X-N

HTTP response header

Occasionally you'll see a response from Akamai that contains the following obscure header. X-N: S. This header is added to accommodate a bug in Netscape when the response headers have a certain length. If the terminating of the header begins on character 256, 257, or 258, then Netscape *used* to display a broken image. Akamai fixes this by padding the headers with X-N: S.
