Why is XML uppercase but HTTP isn't?

Why isn't the "Http" in XMLHttpRequest() uppercase if "XML" is? They're both acronyms. This seems inconsistent or is there a reason? Thanks.

Hey guys,

It's actually because XML (Extensible Markup Language) is a Proper Noun and, therefore, needs to be capitalized. Whereas, Http (Hypertext Transfer Protocol) isn't a Proper Noun (it's more of a 'process' or action), thus doesn't need to be capitalized.

That's just my interpretation on why. :) :dizzy:

The closest I can come to a potential explanation is that in some practices, a distinction is made between "short acronyms" and "long acronyms", where short ones are given all caps, but long ones are treated as words. I suspect the individual(s) responsible for this name may have applied that naming strategy.

Thanks for quick reply Steven. I was wondering what sort of logical explanation there may be. That does make sense. I was more curious than confused. :D
