Reload Document into Google Docs Viewer (Clear Cache)

Question

Google Docs Viewer (http://docs.google.com/viewer) creates a cache of a document after the first viewing. To see what I mean, try the following:

1. Upload file.pdf to your server (i.e., http://example.com).
2. Visit http://docs.google.com/viewer?url=http://example.com/file.pdf
3. Upload a new file to replace file.pdf (but use the same name).
4. Revisit http://docs.google.com/viewer?url=http://example.com/file.pdf.

Google Docs Viewer still shows the old file.pdf.

Anyone know how to correct this?

(I have already tried clearing browser cache, switching browsers, and logging in with a different google account to view the link.)

Answer 1

It appears there is no way clear the cache. Although, from my experience, Google tends to do it automatically about once a day.
