Thank you François! Thanx to your advice, I've solved my problem. I had to recompile Apache2.2 in order to have the needed proxy modules, then I just added this lines in the config file of Apache #1 (port 80): --------------- begin --------------- <IfModule !mod_proxy.c> LoadModule proxy_module modules/mod_proxy.so </IfModule> <IfModule !mod_proxy_http.c> LoadModule proxy_http_module modules/mod_proxy_http.so </IfModule> ProxyRequests Off ProxyPass /aleph http://svr4.sbt.ti.ch:90 ProxyPassReverse /aleph http://svr4.sbt.ti.ch:90 ProxyPass /atest http://svr4.sbt.ti.ch:91 ProxyPassReverse /atest http://svr4.sbt.ti.ch:91 ---------------- end ---------------- Maybe there is also something not relevant, anyway it works now great with 3 Apache and 4 Tomcat, all through port 80 :-) Thank you and best regards, Stefano --- Stefano Unternaehrer - 6500 Bellinzona - 091 8141513 Informatico Sbt - Sistema bibliotecario ticinese stefano.unternaehrer@xxxxx http://www.sbt.ti.ch --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
