Create an absolute 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  |
|LinkedPage              |LINKED PAGE   |true  |
|LinkedPage.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?responder=symlink&linkName=SymLink&linkPath=.LinkedPage.LinkedChild|303|
