Some time ago the Dutch on-line newpaper "De Telegraaf" changed
someting
with their website of webserver.
Since that moment their website http://www.telegraaf.nl/ can not be
connected if the browser is using the Bordermgr proxy. This is
happening
at our own office and at the infrastructures of our customers. They
all
use BorderManager (several versions including 3.5 and 3.6).

I have to wait for a long time and we get a 504 error.

I tried this:

1) use these settings - from TID10019250

SET USE SPECIFIED MTU = ON
SET MAXIMUM INTERFACE MTU = 576
SET ALWAYS ALLOW IP FRAGMENTATION = ON

2) setting up a caching "exception" for the domain ending with
Telegraaf.nl

3) stopping IPX en IP filters

4) unloading & reloading PROXY with -CC (clear cache)

Has anyone suggestions (or can test the site with using BM)?

Regards,
Martijn
