Par défaut Maximal Requests/User for Apache 2.0.55 with Bea Weblogic module von Windows 2003 Enterprise Editon

Hello,

we are running Apache 2.0.55 on Windows 2003 with the Bea Weblogic
module with mod_ssl. We have the problem that user often have to
request a page twice. After the first request the Browser shows a page
could not be displayed message. Mostly, after the second request the
page can be displayed. We are currently investigating how we could
solve the problem. Currently we have round about 500 user with 2000
page requests per hour. We expect up to 2000 User in the future. We
currently investigate in the configuration of ThreadsPerChild=250 and
MaxRequestsPerChild= 0. Is it possible that we have here too low
values? Our configuration looks like this:


################################################## ## http.conf

KeepAlive On

MaxKeepAliveRequests 100

<IfModule mpm_winnt.c>
