It really should've been called GRRTP, Generic Request-Response Transfer Protocol, because there is nothing in it per se that's catered to hypertext transfer specifically. For comparison, look at FTP: it really is about the file transfer, you can tell that that is its application domain. Then look back at HTTP... yep, a generic request-response protocol, suitable for building pretty much anything else on top it.
