• Re: Difference between MSXML2.XmlHttp and Microsoft.XmlHttp ProgIDs

  Your right - I don't think using the deprecated namespace is the right way to go - also the code from Dojo above doesn't test for the lastest version (MSXML2.XMLHTTP.6.0). I use the following code (as per M$ recommendation): var tr = !!window.clientInformation, progids = [ 'MSXML2.XMLHTTP.6.0' , 'MSXML2.XMLHTTP.3.0' , 'Microsoft.XMLHTTP' ], sProgid = null ; // Wrapper for IE's ActiveObject if (tr && !window.XMLHttpRequest) { // Returns null if the ActiveX

  @Nath-22 Remember MSXML is not tied to a particular browser version and can be updated independantly. I still think it's lack of good documentation - I can find no evidence that say, DOJO (for instance) is doing anything special with Msxml2.XMLHTTP.4.0 -- unless someone from Dojo (or any of the other js toolkits) wants to comment? Latest Version (1.2.3) // These are in order of decreasing likelihood; this will change in time. d._XMLHTTP_PROGIDS = [ 'Msxml2.XMLHTTP' , 'Microsoft.XMLHTTP'

  Hi there webjose, Just goes to show how crap/confusing MS documentaion is - posting to a 2yr old thread! I think the original question was more of a why do 'all' the Ajax Libraries test for MSXML2.XMLHttp.3.0, Microsoft.XMLHTTP, MSXML2.XMLHTTP when Microsoft.XMLHTTP will suffice? I stand by my original answer - lack of good documentation from MS. But the bigger question to ask is "is this really relevant any more?" - Do you still want to support outdated web browsers for this type

  @eric Hi Eric I just wanted to clarify something with you, are you saying that legacy browser support (e.g. IE 5.x) requires the use of both MSXML2.XMLHTTP and Microsoft.XMLHTTP? Cheers, Wukfit

  I wasn't implying that you were a beginner I've no idea what the level of knowledge/experience is of people posting to this forum - so please don't take offence. OK Just to back up my reasoning for why AJAX frameworks test for multiple versions of the progid... This snippet is taken from a recent version of the YUI (Yahoo) Library: YAHOO.util.Connect = { /** * @description Array of MSFT ActiveX ids for XMLHttpRequest. * @property _msxml_progid * @private * @static * @type array */ _msxml_progid

  OK I guess I'm not understanding the questions you want answered so I'll try to answer each of the questions in your initial post.... Q: Could someone explain me the difference between following version independent ProgIDs: MSXML2.XmlHttp and Microsoft.XmlHttp? A: There is no difference, Microsoft decided to change the namsepace from Microsoft to MSXML2 - they will both instantiate the same version of the MSXML object - which could be MSXML 2.0, MSXML 2.6 or MSXML 3.0 Q: Which one is preferable

  Just in case anyone else looks at this thread.... I think I understand your question - you're right from what I've read it's pointless testing for MSXML2.XmlHttp, Microsoft.XmlHttp (AND MSXML2.XmlHttp.3.0) as they will all point to the same version - and theres no way to tell which version this is. The 3 progids (MSXML2.XmlHttp, Microsoft.XmlHttp and MSXML2.XmlHttp.3.0) reference v2.x to v3 of MSXML, which would have been installed in "replace mode" (installing version 3 replaced
