Does anyone know an example of VS Code extension making use of it?

[akosyakov]

git extension makes use of it https://github.com/microsoft/vscode/blob/master/extensions/git/src/protocolHandler.ts#L10

It seems to be used in VS Code in open url action with https://github.com/microsoft/vscode/blob/7bc29bf67c17608b11e23a8497c8f1de5a0922cf/src/vs/workbench/contrib/url/common/url.contribution.ts#L32

I think it's useful for electron mode, but I don't know how to handle it correctly on browser mode.

I think it's useful for electron mode

Can you elaborate? I still cannot get my head around where it is used.

My plan is to add Developer: Open URL command, similarly to VS Code. But i wonder whether it is used somewhere else?

@akosyakov I was thinking that URI Handler are for the system

so let say I register foo: URI handler, if I enter in my browser foo://bar then it can be handled
but in Theia used in browser mode, system handler is managed on the server side so even if I enter in my browser foo:// it won't be intercepted.
IMHO It's really working only when remotee and client are on the same machine
