I have a drilldown page in which I can drill down 3 levels exactly, always.
I want my URL to look like this:
drill
- main page
drill/:l1
- drill down to l1
drill/:l1/l2
- drill down to l1 then to l2
drill/:l1/:l2/:l3
- drill down to l1, then to l2, then to l3.
All of them function the same, with just different data, and currently I use $
to separate them, like drill/l1$l2$l3
and know which level by the $
sign.
Is there a way to make it an optional segment of drill/:l1?/:l2?/:l3?
?
