Charles,

Your configuration is very different from mine, so I may not be able to help
much, but maybe I can give you an idea or two on where to look.

Bad Request is frequently associated with a mal-formed URL.

What browser are you using, and if you've tried other browsers, does the
error occur with all of them?  In particular, I've noticed IE will try to
fix some bad URLs, while Netscape/Mozilla won't.

What does the URL of the link you're clicking on look like?  Does it result
in a redirect (that may be different depending on the elapsed time)?

I realize not much of this pertains to the time lapse you mentioned, but it
really sounds like a problem between the browser and Apache, and the
possibility of a non-deterministic redirect url is the only thing that comes
to mind as the possible cause of this problem (and I don't think even IE
will attempt to fix bad Location headers.)

Hope this helps in some way,

Jason
