Maybe you should do it, because the protocol tells you to: "User agents SHOULD include this field with requests." http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.43 The meaning of SHOULD is defined in BCP 14: "This word, or the adjective "RECOMMENDED", mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course." http://www.ietf.org/rfc/rfc2119.txt You have the liberty of being protocol-ignorant, but you should not blame a free public service for informing you about his.
