According with the documentation, I've tried to setup a load balancer apache2.2.x/tomcat5.5.x; I'm unable to maintain the session.
my conf: apache2.2.9/tomcat5.5.26/jdk1.5.0_15,linux redhat5.2 apache side: RewriteEngine On ProxyPreserveHost On ProxyRequests Off ProxyVia Off <Proxy balancer://a> Order deny,allow Allow from all BalancerMember ajp://vmwaretest08:8009 route=vmwaretest08 loadfactor=1 BalancerMember ajp://vmwaretest08:8010 route=vmwaretest08 loadfactor=1 BalancerMember ajp://vmwaretest08:8011 route=vmwaretest08 loadfactor=1 </Proxy> RewriteRule ^\/(.+)\.jsp(.+)? balancer://a/$1.jsp$2 [P,L] ProxyPass /favicon.ico !

It seems ignoring the parameter stickysession=JSESSIONID|jsessionid and/or the parameter nofailover=On The same env. with apache2.0.x/mod_jk1.2.x works instead. Any suggestion[s]/idea[s]???? Michele
