STSNavigate() still prompting for credentials when trying to open a document

Question

Here is my scenario. We have setup a public facing site the utilizes a Web Application that searches a internal SharePoint 2010 site. The web app utilizes the SharePoint QueryService to search the site. We provide credentials to the service as the SharePoint
site is not an anonymous site (although if the QueryService worked with the site being anonymous that would satisfy our requirements). The Web server allows anonymous access to the web app through IIS. I have found that utilizing the STSNavigate() function
SUPPOSED to allow the document to be downloaded or opened without prompting for credentials. I modified my search results link to include the function on click and low and behold it still prompts for credentials the same way it would if the url just had the
link to the file. I am on a time clock here and I am running to the end of my rope. Any suggestions?

Hi,
According to your post, my understanding is that STSNavigate() still prompt for credentials when trying to open a document.
Per my knowledge, if you try to open an Office file directly from a remote place, Office wants to know who the hell you are. If the server responses with the
Microsoft Office Protocol Discovery or a
FrontPage Protocol or a
WebDav Protocol
Then  it ask you for  credentials.
As a workaround, I recommend to  “init.js” located in \Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\1033 folder.
You need to add this it:
STSNavigate(ctx.HttpRoot + "/_layouts/download.aspx?SourceUrl=" + o);return false;
