Hosting certain pages on a different domain in an iframe produces weird results
Folks,

I am working on an app that hosts certain pages from a different site in an iframe.  Because the site is on a different network, I get prompted to log into their network in order to show the pages.  All that is fine (the users of this site will be on the same network, so I'm not worrying about their logging in.)

However, on a different page, same app, I'm trying to do the same thing with a different set of pages from that same site.  This time, I don't get prompted to log in, but do get the DNS Error page in the iFrame (I'm doing this in IE9, if it matters.)  If I click "return to previous page" on the DNS Error page or right-click and click Back, the home page of the app (on the different network) appears in the iframe.  After that, trying to load the desired page in the iframe works.  But I'm baffled as to why and would prefer it load the first time I try it!

I'm guessing that the conjunction of the hosted pages being secure (HTTPS), their being on a different network, the iframe, and possibly also IE9 are somehow causing this.  Anybody have any ideas?  

Thanks,

Ann L.
