This is a complicated setup and issue, so I'll do my best to keep it succinct:
There are two different web applications - one is Windows authentication, and the other is Forms authentication.
Application #1 (Win authentication) uses a RadEditor to create "posts" or "articles" that could have images within them. Those images are currently saved/uploaded to a directory that resides in the IIS root. I've also tried with a virtual directory.
Application #2 (Forms authentication) loads the HTML from these posts created by App #1 into a Literal Control. Whenever App #2 loads a post that contains an image, the browser asks for domain credentials. The image will not show unless you supply proper login info. The rest of the HTML from the post will load fine - just not the images.
I've given permission to the app pool, IIS_USRS, IUSR - even full control. So far, there is no difference whether this folder has proper permissions, or none... it still prompts for credentials.
How can I allow App #2 to access these images without requiring credentials?
Thank you, in advance.
