Subject:      OT: Incorrect file size reported,
              especially for PDF files from IE6.
Content-Type: text/plain; charset="us-ascii"

Off topic, except that it was a SAS paper I was downloading:


When downloading a PDF file the other day, the progress bar in Internet
Explorer 6 (bottom left of the screen) indicated I had progressed to
"DOWNLOADED 1GB of 3GB".

I didn't take a lot of notice of it at the time, I had other competing
demands on my time.

The actual file size was 3MB, but this apparent file size inflation
caused a number of problems subsequently.


Adobe on line help didn't tell me much last night, but this morning I
found "http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=6a620259"
which suggests that Flash player 9 is now using the server text data
rather than referrer data to determine the size of the content.


Has anyone else seen this anomalous behaviour?  Can you shed light on
the issue?


I was finally able to reproduce the problem with another file yesterday
which reported 2GB rather than 2MB for the file size. It was at least
encouraging to know that I had correctly read and understood the
progress bar message.


My overarching issue with this is that I can't clearly identify whether
it is Adobe at fault as the target application, IE at fault because of
its use as a file locator, or the proxy that sits between the browser
and the BBI (Big Bad Internet) and produces some very strange results
when you download larger SAS patches.

Kind regards

David
