Hi Team,
I am facing a strange issue suddenly. PFB for more details:
I have a website deployed in IIS 8.5 and Inside the website we have file folder "Chart" that contains .png images. Till, October 2016 we are able to show these images on web page.
But, suddenly its asking Authentication "username and Password" while accessing this page. When we separately browsing image also same result. This happens only from Mobile devices. Desktop its working. If we access first desktop and then mobile also working. Only it we access first time from Mobile it is not working. PFB for the scenarios I have tried:
We are having Anonymous, ASP.NET, Forms and Windows authentication enabled. Please review and let me know Am I need to check any settings to resolve this issue.
