one use case, the key was having HTTPEnableConnectorHeader
Without the above ini we cannot reproduce, we have tried
on about 10 different machines, new installs over installs etc, however,
if the ini is present in the notes.ini we can reproduce the issue. We have
installed new servers many times taking all the defaults and still cannot
make it happen. I attempted to exactly what you did Windows 2008r2,
both 32 bit and 64 bit versions production version, created a key ring
file, set the bit on webadmin.nsf to redirect to ssl and everything works
as it should, no redirection loops.
We do believe you that you are having an issue, we just
cannot figure out how do get it to reproduce. We have one code path/configuration
combination that makes it happen, but it sounds like there may be another
one as well.
