Subject: Re: [users@httpd] Apache, Tomcat and mod_proxy

Hi,

Thanks for your analysis, Karel. I'll try a larger timeout (60 seconds
was used in my unsuccessfully last test). However, recently I put 300
browsers to access Apache connect to Tomcat using mod_jk without any
problem. Unfortunately, I suspect this could be a bug with
mod_proxy...
