Generate URL session - Use only Shell: default

Hello,

I would like generate multiple URL to connect to whole servers list.

I saved a session that's working in WinSCP (5.19.6), then I did a right click to generate URL session. But when I use the URL, shell command is not execute.
In my session list, I select sudo su - in shell options.

URL looks like:
I enabled session log file in WinSCP and I see "Shell: default"!
I don't know how to find a solution.

Thanks for your help.

How exactly are you using the URL? What are you trying to achieve?

The x-shell parameters is indeed ignored, unless you remove the /Unsafe switch from Windows protocol registration:
Bug 1943 – Prevent loading session settings that can lead to remote code execution from handled URLs

I would like to generate a HTML page with a list of servers.
If I click on a hostname server, it will open WinSCP.

But who is the intended audience of the page? Do you have control over their computer? Can you change their WinSCP URL registration?

Only few persons will use it.

My goal is to get a list of servers and IPs from a database. Each person will generate its own page HTML to get access to the servers.

So they will have to change their protocol registration to add the /Unsafe switch.
