Hi , we have web-published our internal web based application with isa2004 . We have replaced old reverse proxy netscape 3.6 . our web based application is installed on 6 web-server IIS and on our isa we have published a virtual ip address (balanced ip with cisco load balancing hw CSS ) . seem that ISA doesn't maintain affinity with web server or isa send all packets ( packets optimization ??? ) to 1 web server ... any idea ?
