How should I approach this issue?

I want to create one page, but many "virtual pages", e.g. like a productinfo.php. A product has several. In this case you manually create the posts in the database through dashboard and the virtual pages are pointing to specific posts in the WP database.

What I want is this is kind of same thing but I don't want to add any posts and I want all virtual pages to redirect to same page with different GET request:

Let met explain:

1. I create one page: e.g. cityinfo
2. If I go to /luton it should point to cityinfo?actualcity=Luton
3. If I go to /london it should point to cityinfo?actualcity=London etc.

Should I be using .htaccess for this? Or am I missing some easier way to achieve this?
