[Zope] Serving external files

[Phil Harris]

Allen,

Try looking at the LocalFS product available on the Zope.org site.

It makes folders on the physical drive look like part of the ZODB.

>        RESPONSE.setHeader("Content-Type", "application/data")
>         return data
> 
> The zope id of the external method is "getFile".

> I have a dtml method that calls this external method, using
