The named constants for header fields of the response struct all pretty much matched the actual header name, which I think improves readability for everyone familiar with the HTTP-spec. The request header fields named constants followed the rule, except the "If-Modified-Since"-header, which is addressed in this commit. Signed-off-by: Laslo Hunhold <dev@frign.de>
