This one bugs me since years, and I'm guessing it may not be solvable:
When clicking the link to a document (let's say a DOC file) inside Internet Explorer on a SharePoint 2010 website, Internet Explorer somehow instructs Office to start up and load the document via WebDAV (I guess it is WebDAV).
In contrast, if I do the same in any non-IE browser (i.e. Google Chrome, Mozilla Firefox, Apple Safari or Opera), the click on the link to a document simply downloads the file instead of passing the URL on to the office application.
My question is:
Is it possible to configure the server or the browser (both server-side solutions or client-side solutions are suitable in our environment) to not download a copy of a document but instead pass the request to the appropriate application?
Update August 2015:
Since Windows 10 and Microsoft Edge browser is now officially released, I tried to open SharePoint documents from within Edge.
And it works! The document actually gets openend in Office and not getting downloaded.
Since from my understanding, Edge does not suport ActiveX there has to be some kind of other mechanism going on here.
