How to Add Custom Tag in Web.Config Page (ASP.NET)
To add a custom tag to Web.config you need to first explicitly specify the new tag name in Web.config via the tag
For Example:

type="System.Configuration.NameValueFileSectionHandler,
System, Version=1.0.3300.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />

tag indicates that we are going to be adding New tag named MyAppSettings.
Now we can add a tag to our Web.config file and
add tags to add application-wide parameters,
For Example:

type="System.Configuration.NameValueFileSectionHandler,
System, Version=1.0.3300.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />
