IE 8 has difficulties with local files, even if on same origin path. A change to xhr fixes

Reported by: scaddenp Owned by: tschaub
Priority: major Milestone: 2.10 Release
Component: Request Version: 2.8
Keywords: IE local access Cc:
State: Complete

Description

The problem lies with IE implementation of XHR. Fix is change request/xmlhttprequest.js

Change the function cXMLHttpRequest() to this.

function cXMLHttpRequest() {

this._object = oXMLHttpRequest && (window.location.protocol !== "file:" !window.ActiveXObject) ?

new oXMLHttpRequest

: new window.ActiveXObject("Microsoft.XMLHTTP");

};

This ensures it uses the activex for local file access.

  • milestone changed from 2.8 Release to 2.10 Release

Milestone 2.8 is in the past. Changing to 2.10.

Phil, can you do a few things: 1) check if the problem also occurs when you use the latest version of the XMLHttpRequest library ( http://code.google.com/p/xmlhttprequest/), this is most likely the case. 2) if this is the case, can you raise the issue there as well (see also  http://code.google.com/p/xmlhttprequest/issues/detail?id=23 which seems related).

Problem is still present in the latest version. I have posted on the issue there as suggested.

Phil, the creator of the XMLHttpRequest library has applied a fix (and released version 1.0.4), see:  http://code.google.com/p/xmlhttprequest/downloads/list

Is this something you can test?

Phil, if you need a patch to upgrade OpenLayers to version 1.0.4 of XMLHttpRequest please see  http://trac.openlayers.org/attachment/ticket/2625/xmlhttp104.patch

I've had confirmation from Phil that XMLHttpRequest 1.0.4 fixes his issue: 

> can you try with the attached XMLHttpRequest.js, just drop it in your OpenLayers
source tree. TIA.

Boy its frustrating trying to learn too many things at once. Should have 
diffed the see what I needed to do but I am only working a few hours a 
day at moment.


Anyway, to the substantive point. I dropped your attachment into tree 
and it works. Tested with FF, IE8, Safari, Chrome 4. IE8 was the 
critical one and it worked fine.
