This is my first post here and I'm hoping that someone can help me.

I have a CGI script that creates a dynamic form. When the user fills in the required information it is then sent to the server for processing. Then a new page is returned to the user that is "updated". What I need to do is prevent the user from using his back button and obtaining the last cached page.

Here's the code I used: 

print header(-type => 'text/html',
             -expires =>'-1d',
             -cookie => $Some_information, 
             -Pragma => 'no-cache',
             -Cache_Control =>'no-store,no-cache,must-revalidate,post-
+check=0,pre-check=0');

This works great in Firefox, but it DOESN'T work in IE or Opera. What's my problem? By the way, before testing, I deleted all of each browser's cache. If any of you could offer any help I sure would appreciate it.

Thanks in advance...Mike
