hi, I am developing an application service provider site. different people can register there, and they will get their own homepage and data (sensitive data like credit card info etc). currently i have created different folders for each user and gave it names (DNS) like user1.mysite.com, user2.mysite.com etc. from that folders index page users will reach www.mysite.com:8080/login.jsp. (/var/tomcat4/web-apps/ROOT/login.jsp) now i want to customize the code for each user, so i am planning to use multiple instances of tomcat. what are the disadvantages of using multiple instances of tomcat? later if i want to move one user to another server will there be any problem (because i don't want to change the url for that user, ie that should be user1.mysite.com always.) and I need SSL also, how multiple instance of tomcat will effect SSl enabling of my site? thanx in advance Robert AndreaGet more from the Web.
