[Zope] redirect after file upload

hello people, I managed to upload a file to the external folder with plonelocalfolderng and simultaniously to a database. but as you all know, after uploading a file with htmlformuploadfile, this automaticly redirects to plfng_view. but I made my own view of the files available in the folder, based on the content of my database. So after upload, I want it to redirect to this page again, and not to the plfng_view of plonelocalfolderNG. I tried putting a javascript in this file, and changing the links in plfng_view, but I can't seem to find just where to put it. maybe someone can help? thanks Olivier
