The published website’s asynchronous call fails to run on the client’s Microsoft IE browser. When the website is added to Internet Options > Security > Trusted Websites the asynchronous call succeeds and everything runs smoothly.
I have repeated this, less than desirable, fix to two different machines’ browsers, and each time the fix works.
The problem is having to repeat this awful fix on every client’s bowser. Is anyone aware of a better fix than this?
