Is your feature request related to a problem? Please describe.

I am creating an email client and rendering HTML emails using an iframe. When the HTML content uses a protocol relative URL (e.g. //fonts.googleapis.com) the application attempts to use the wails: protocol and an error is returned.

Describe the solution you'd like

Is there some way to proxy requests made to the application? So when the browser code makes the request to wails:// the app will forward it on to http:// and then return the correct response?

Describe alternatives you've considered
