Wisej dynamic route for startup

Hi I’m new to Wisej and just started converting my winforms application to wisej.

I would like to make the application multi-tenant and I was hoping I could do this by url

So a client could have a custom login screen at a dynamic url

so for example:

http://www.mywisejapp.com/myloginportal

It looks like I could do this with a sub-application, however I would like to just read the url folder to determine the client portal and then set a session variable to customize the default entry point login page.

Is this possible?

Also is there a way to just route back to the default route if an illegal route was entered by the user?

Thanks,

Devin
