javascript - Why should I test for MSXML2.XmlHttp and Microsoft.XmlHttp version-independent ProgIDs? -

I have read about it.
And does not help me
Checking Microsoft.XmlHttp as far as I can is enough

1. Can you confirm? (Applying the post)
2. Is there a solid source that describes the non-UTF chromatic association Iv? Is this MSXML 2 Is handled better by XMLHTP?
3. Is there any preceding version of IE which is needed Microsoft.XmlHttp ?

You should check MSXML2.XmlHttp, not Microsoft.XmlHttp , As has been said

They are rarely the same for somone with IE4 or IE5, but do you really want to support it? This post is from people building MSXML, you can not find any more reliable sources.

Like a jquery bug, no one can confirm it because XMLHTTP problems are not related to IE, but the version of the built-in XMLHTTP object Since MSXML3 has been regularly served by Microsoft, XMLHTTP version IE Trusting, can change at any time.
