Hi Immanuel,
Perhaps you should consider using HTTP POST and creating a save.xq
similar to the one in the Beginner's Guide. The problem with PUT is
that you must make sure that you have write access and this opens up
security concerns. HTTP POST allows you to use the request:get-data()
to get the incoming data file and then do an xmldb:store()
Here is the submission line:
<xf:submission id="save" method="post" action="{if ($new='true') then
('save-new.xq') else ('update.xq')}" instance="my-task"
replace="all"/>
