Once mean the first time the page is loaded, but be aware it's loaded in every 
Apache child, so it maybe  loaded multiple time (in different child 
processes) if you hit reload.

As part of the compiled Perl code of the page

[! !] does also allow to do this, but on the second time the page is executed 
then the [! !] block is not run and for that reason your variables will not 
be defined.
