问题
I am enhancing our web framework to use web services and one of features I would like is the ability to view XML that has been submitted. I am using our Java servlet to launch a popup and serve the XML and this works - in IE7 I get the expected behaviour when of a nicely formatted and folding view of the XML. The problem is if I select 'View Source' I get a popup saying "The XML source file is unavailable for viewing".
I've used Fiddler to inspect the response headers which I've provided below:
HTTP/1.1 200 OK
Date: Tue, 08 Sep 2009 15:23:56 GMT
Server: Oracle Containers for J2EE
Content-Length: 7835

Connection: Keep-Alive
Keep-Alive: timeout=15, max=100
Content-Type: text/xml; charset=UTF-8
Expires: Tue, 08 Sep 2009 15:23:59 GMT
Can anyone explain the reason for the error? I have a feeling it might be to do with caching but I haven't been able to solve it yet. The XML is valid and well formed.

This behavior is by design:
