Different link types viability

I want to use a link inside one of the widgets. 

Which widget specifically?

Sorry, let's say not widget, but the Rich Text Editor.

Are you asking how to put in a link to a windows network share, or linux network file store share, as opposed to a HTTP or FTP link?

I feel that there's critical detail here being missed in your request and some assumption of understanding what you're asking.

It’s a link to intranet web-sites accessed over HTTP or HTTPS.

For example https://intranet-resource/
