// AddCookie adds a cookie to the request. Per RFC 6265 section 5.4,
// AddCookie does not attach more than one [Cookie] header field. That
// means all cookies, if any, are written into the same line,
// separated by semicolon.
// AddCookie only sanitizes c's name and value, and does not sanitize
// a Cookie header already present in the request.
