Apache server + Jserv + GNU JSP

[Damjan]

Hi,<br><br>this is a question from a newbie in the area of Web and application servers development although I have many years of experiances in software development from other fields.<br><br>I have a scenario in mind for a Web portal that uses a combination of Apache running as a Web server, Jserv servlet server and GNU JSP package working together for serving user requests. The idea is the following: the Apache server would forward appropriate requests to Jserv which would retrieve the appropriate servlet for the page by using the GNU JSP package to retrieve the JSP file from the repository in the back-end and compile it to a servlet.<br><br>Also note, that my portal would require users to log-in before using its services.<br><br>The question: would this architecture allow me to serve approximately 40000 concurrently logged-in users with a maximim of 0.5s response time per users. (Let's assume that getting the JSP page from the repository is not time consuming at all and that JSP pages are small to compile. Let's also assume I can not change the architecture.)<br><br>What do I need to especialy take care about (any first-hands experiances?) <br><br>More Apache and Jservers sharing the repository?<br><br>Hardware (platform), physical memory?<br><br>Anywher on the web where I can get more info?<br><br>Misc?<br><br>Thanks in advance...<br><br><br>Damjan
