So I am just getting started with Umbraco...

What I would like to do is this

www.website.com/CompanyA (start page)
++++++++++++++/Page1
++++++++++++++/Page2
++++++++++++++/Page3
++++++++++++++/CompanyB(start page)
++++++++++++++/Page1
++++++++++++++/Page2
++++++++++++++/Page3
(the plus signs are just so I could get the formatting)

The start page for the companies will be the same, except for a custom company logo, or maybe just their company name.

The pages 1-3 are also basically the same templates, except for the possibility for some companies to have a custom page 4.

What I am thinking about is using route hijacking in Umbraco. At the controller, I build the correct start page partials, and subsequent pages partials, based upon the lookup for the user's company.

I have some idea of how I would do this as a regular MVC5 application, but it seems I am getting lost in the Umbraco documentation.

I am not asking for a step-by-step : more of a study this, or look at that example.

Thanks in advance !!
