MS Edge Handles 401 Errors Thus Bypassing My Error Handler

I have code to make ajax calls to my web service in javascript as follows: $.ajax( { url: url, data: json, type: 'POST',

Solution 1:

The cause of this appears to be that, to check for an internet connection, my code made a call to an http site. Because my site is an https site this behaviour was deemed suspicious by MS Edge. So whenever I subsequently tried to access my web service MS Edge stepped in and denied my site access.

I've replaced the call to an http site with one to an https site and all now works fine.
