HTTP Redirect with 302 response

Many ways to solve this. If you do not intend to write your own iRules in the long term, look into LTM Local Traffic policies (no TCL coding required). In case of an iRule solution, here's how I'd approach the problem

when HTTP_REQUEST {

    switch [HTTP::host][HTTP::path] {
        "xyz.com/" -
        "xyz.com/index.jsp" {
             do not interferre
            return
        }
        default {
             issue a temp 302 redirect
            HTTP::respond 302 Location "http://xyz.com/index.jsp"
        }
    }
}
