"Too many Redirects".

I have been attempting to debug a problem (with colours not showing
up) on an internal server.  I've tried a number of browsers,
(Firefox, internet explorer and Opera) but when I remembered Amaya
is more rigorous, I tried that.  It detected bugs in the HTML, but
also it gave me a message about too many redirects.

It turns out that HTTP 1.1 mentions this:

Q> 10.3 Redirection 3xx
Q>         [...]
Q>    Note: previous versions of this specification recommended a
Q>    maximum of five redirections. Content developers should be aware
Q>    that there might be clients that implement such a fixed
Q>    limitation.

so therefore it no longer applies in HTTP 1.1, only 1.0.  I can't find
any means of turning this error detection off.  I agree that it is a
useful warning for 1.0 compliance, but if the client has requested 1.1
then it should not matter, should it?

Searching the archives for previous reports of this problem I found this:


which is about 2 and half years old, but doesn't seem to have been
implemented.  I had six redirect questions to respond to before this
other error message came up, and that was for one submit button.

So in the end I never got to test the page I wanted to access with Amaya.

For completeness:
It turns out to be a bug in XP's high contrast mode, which is
apparently off (Most things are not high contrast and I have a
background image in the desktop, rather than a single colour), but
toggling the mode with <ctrl-alt-print_screen> still took me out of
that mode.  When you go into the mode you get a confirmation
dialogue but coming out you don't.  Don't experiment with that mode
unless you want your icons moved about and the fonts changed.
Toggling the mode on and back off does not leave your screen as it
was in the first place, unless you already use the mode..

        Thank you,
