if I have a bean that is called from a jsp and has the call
and in my jsp
mybean.init( request, response);
However we have found that some versions of ie if they mess with the back
button and up with messed up pages (described below).
1) how can i fix it?
2) Then would you say it is not safe to redirect from a bean that you have
pass a refrence to http response?
