I’d start by finding out whether the challenge is coming from the proxy server or not. Packet capture on the proxy server can probably help you here, as it should show what the proxy server is doing vs. what is coming directly from the web server.

It identifies itself as an earlier version of IE tahn the version installed as the browser. -- noonie On 19 May 2014 19:22, <anthonyatsmall...@mail.com<mailto:anthonyatsmall...@mail.com>> wrote: I would assume word is using the IE to grad the urls, hence if you have logged into the website using IE, then word may be aware of this?

When they copy text from a Web page into Microsoft Word they are prompted for credentials on one site but not on another, similarly configured, site. Both sites are basic auth over https and both are ASP.net apps with very minor differences. The major differences are in their proxy configurations. I can understand why credentials are required but not why they seem to be automatically offered in one case but not in the other. Where can I find some documentation about how Windows and Office conspire together to grab CSS files so Word can decide what text formatting to offer? -- Regards, noonie
