Windows-8/MSIE-11 introduced Tiles, as such server administrators may have started seeing HTTP 404 errors in their server logs as it attempts to look for a “browserconfig.xml” file at the root of a website domain. If you are inclined to use this file, you should definitely look into the documentation for how to best make use of it. Others may just wish to prevent the error from making “noise” in their log files.
To remove the error, add the following to your pages; alternately you COULD define the URL of your file as the ‘content’ attribute:
<meta name="msapplication-config" content="none" />
You can alternately place an empty
/browserconfig.xml on your web server for each domain.
An common example of how to use this file is below:
<?xml version="1.0" encoding="utf-8"?>
<TileImage src="/mstile-150x150.png" />
