[Seaside-dev] How to ensure a script appears only once on page?

     self session addLoadScript: ...

Adds a small snippet that will be evaluated when the page has loaded.
If you want you can also query

    self session onLoadScripts

what scripts already have been added. However this scenario looks more
like you should rather use a static script from a file-library.
