[Zope] Set expire date for file

[Tino Wildenhain]

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
