[users@httpd] nokeepalive downgrade-1.0 force-response-1.0 ssl-unclean-shutdown for IE6

[Rainer Traut <tr...@gmx.de>]

Hi,

we're running apache 2.2.3 on Redhat EL4.3 x86_64
with mod_proxy_ajp for our backend tomcat.
All traffic is https.

To tweak performance for our IE6 users we tried to leave this line
commented out of our ssl.conf:

BrowserMatch ".*MSIE.*" \
          nokeepalive ssl-unclean-shutdown \
          downgrade-1.0 force-response-1.0

Our observations are:
you can leave this line out if there is no forward proxy on the client
side.
If it is we ran into problems, like error messages in IE6 'page cannot
be displayed'.
On a fully patched XP SP2 IE6 the connection problems were very rare but
they existed. So it is difficult to reproduce the problem.

The question is, can we allow http 1.1 for the IE6 users?
Or what parameters are safe in this situation?

Thanks
Rainer
