iFrame in IE6 & 7

We are trying to use the control in an older ASP application using an iFrame window. It works fine with a Foxfire browser, but has sporatic results with IE 6&7 - seems to work on one site but not on another. Any suggestions?

One of my talented employees found me an answer.

IE needs to fully flush the cookies for this iFrame call. (Firefox works fine out of the box...)

FIX- Flushes cookies so iFram will work in IE.

Tools>Privacy>Advanced> 

Check:

Override Automatic cookie handeling
Accept First-Party Cookies
Accept Third-Party Cookies
Always allow session cookies

Problem is back. I'm not sure why it's not working now. Problem with FoxFire now also.

FV Control in iFrame will not open.

Any suggestions?

Hi Xan,
Are you sure it's still a cookie issue. Does FileVistaControl display when you open the host aspx page directly?

See the below page, it may help you:
How to set third-party cookies with iframe

I don't think it's a cookie problem now. I checked the error log and it seems that my developer has the site in the ASP.NET 2.0 AppPool on IIS 6.0 and the FileVista control running in another AppPool. This would account for it seeming to work then stop, once the AppPools become confused.

We are trouble shooting it today and will see if we can solve the issue.

Is there a recommendation you have for the default AppPool when using the control in an iFrame application?

I think there may be some authentication related issues as you only have problem with IE and not Firefox. For instance IE automatically accepts integrated authentication but Firefox does not.

I can recommend you to run them in the same application pool.

Let me know.
