Hi Sven, the constructor of images and files looks like this: def __init__(self, id, title, file, content_type='', precondition='') the optional precondition can take the id of a method which is called when the image/file is published, e.g. its index_html methods gets called. You only have to make a method in the acquisition path wich reads this (in dtml) <dtml-call "RESPONSE.setHeader('expires',_.DateTime()-1.0)"> <dtml-return "''"> or something like that. Use manage_addImage( id, file, title='', precondition='name of your method', content_type='') or manage_addFile() repectively HTH Tino Wildenhain --On Freitag, 27.

Hello,
How can I set expiring date for a file (xls, gif, etc.) so it will be downloaded from server not from cache. HTTP header?
Or is there another way?
Sven
