   I have one, but it is big and ugly (it based on my entire application).
Do you really want to see it? If yes - I'll try to clean it up and send it
to you. (I am saying "try to clean" becuase I suspect the bug may disappear
if I convert my HTML pages to English, or do something other what I cannot
do in the real application...)

   The bug is triggered by a number of conditions. First, the browser and
the server must be on the same computer; because of this very few people at
all can trigger the bug.
   Second, it depends on a content. I have a form with a number of inputs;
once I cleared the bug by changed "name" attributes of the inputs from
composite names like "OperationCode-ResourceCode-etc" to just "Field1",
"Field2"... etc. The bug disappeared... for a time, and reappeared when I
increased the number of inputs in the form.

   The M$IE behaves like this. User submits the form, server processes it
and sends a redirect to the same URL; user modifies inputs and submits the
form for the second time. This time IE sends 2 (I said "two"!) POSTs, and
whaterver server replies (whether it is HTTP 200, or 303, or 404) IE
complains "DNS Error". Other browsers (I tried Mozilla for Linux and for
Windows) work fine with the application. (That was my fault, actually - I
was developing the application using Mozilla for Linux, and only very
late tested it with IE on Windows. Never use good computer, good OS or good
browser for developing... or at least test it often with bad ones.)

   As I said, I did a brief experiment with Medusa, and found that IE sends
only one POST and behaves as expected. The bug still may reappear, of
course, but how can I predict it without knowing IE internals?

Oleg.
