Hi Friedrich,
I believe that a HTTP HEAD request instead of a HTTP GET request would read the HTTP headers only.
From there, according to the W3 Standard...
the Last-Modified entity-header field indicates the date and time at which the origin server believes the variant was last modified.
Last-Modified = "Last-Modified" ":" HTTP-date
An example of its use is
Last-Modified: Tue, 15 Nov 1994 12:45:26 GMT
The exact meaning of this header field depends on the implementation of the origin server and the nature of the original resource. For files, it may be just the file system last-modified time. For entities with dynamically included parts, it may be the most recent of the set of last-modify times for its component parts. For database gateways, it may be the last-update time stamp of the record. For virtual objects, it may be the last time the internal state changed.
It seems like this would do the trick.
Could it be done from within SetupBuilder?
Regards,
Alex
