Safari caching issue

I have been working on a web script in Perl that allows students to login and schedule exams with our testing center. The script is working for most browsers but will not work with Safari. My management has made it clear that they want the script to work in Safari since it is the most common browser used by our department. So far the script will allow the user to login and download the html for the first page. However, when you click ‘next’ Safari loads the page from cache rather than getting the updated dynamic content. I have added the normal Meta tags to prevent caching but it didn’t affect Safari (see below). I also tried using content expiration via our web server software which didn’t help either. Here are the Meta tags I have placed in the html being sent to the browsers:

I also tried sticking an additional ‘<head><meta http-equiv="Pragma" content="no-cache" /></head>’ in between the </body> and </html> tags as found as a recommendation on one of the sites that cropped up in my many Google attempts. Has anyone else run into this problem and found a fix? Any ideas would be greatly appreciated.
