Can't set cookie in middleware when ownCloud is not installed in a folder

[oparoz]

To test this

1. Launch the VM
2. Add cookie setting code to middleware of an app and redirect to a page (https://github.com/owncloud/gallery/blob/master/middleware/checkmiddleware.php#L150-L159)
3. Add code to landing page which reads the cookie (https://github.com/owncloud/gallery/blob/master/controller/pagecontroller.php#L134-L148)
4. Go to localhost/owncloud/trigger.php

You get the cookie

1. Go to localhost/trigger.php

Now you don't

Notes

It's a simple way to test this, but if you want to discard the methodology, then just set up 2 different instances, one installed in a folder and one installed at / and you'll get the same results.

The problem doesn't happen if you set a cookie in a controller.

Happens on both master and stable8.1

Reminds me of #19010

Same issue - yes.

I wonder if this isn't also the cause of #18891

is this resolved?

[LukasReschke]

Let me try to hook up a debugger on iOS then.

@cmonteroluque - not yet. Will dig into this tomorrow.
