I’ve been looking into an issue i’m experiencing when posting to a server, specifically when opening a Word file from the returned response.
An XMLHttpRequest object via JavaScript is being used to send data back to the clients machine from the web server using the .open and .send functions – the responseText having the resultant XML within.
After looking in Fiddler this request shows the following:

However you can see there’s the red symbol, looking at the Fiddler documentation this means that the “Session was aborted by the client, Fiddler, or the Server.”.
Furthermore the header for the response appears to be correct:


What would cause the aforementioned behaviour? The browser is not displaying any visible script errors (IE8) and i’ve made sure that JavaScript errors are not supressed. Looking at the TextView filter in Fiddler you can see the Word data, mentions of Fonts and styles etc.
Thanks for your time!
It appears the issue was due to a mis-registered MXSML .DLL, after re-registering the DLL in question functionality was restored.
