Create an nested backward symbolic link from a sub-page:

First we need to create some pages to play with.
!|Page creator.|
|Page name.                                                       |PageContents.       |valid?|
|LinkingPage                                                      |LINKING PAGE        |true  |
|LinkingPage.LinkingChild                                         |LINKING CHILD       |true  |
|LinkingPage.LinkingChild.LinkingGrandChild                       |LINKING GRAND CHILD |true  |
|LinkingPage.LinkingChild.LinkingGrandChild.LinkingGreatGrandChild|LINKING GREAT GRAND CHILD |true  |
|LinkingPage.LinkingChild.LinkedChild                             |LINKED CHILD        |true  |

Now we create a symbolic link named !-SymLink-!.  This links !-LinkedPage.LinkedChild-! as a child of !-LinkingPage.LinkingChild-!.
!|Response Requester.|
|uri   |status?|
|LinkingPage.LinkingChild.LinkingGrandChild.LinkingGreatGrandChild?responder=symlink&linkName=SymLink&linkPath=<LinkingChild.LinkedChild|303|
