Since yesterday, we got this error for a web site.

(Error message translate from french)
Error 400 - Proxy Error : unable to establish connection to the origin

This is not a Border Manager error page.

If I bypass the proxy (Uncheck proxy in Internet explorer), it works.

I try with IE and Firefox and I got the same problem.

If I hit CTRL-F5 to reload the page, it works!!

Config : Border manager 3.8sp3 running on netware 6.5sp3.

Any Idea?

Thank you
