Hi all,
I have a big problem when caching with Internet Explorer 6.0. In order to prevent caching to all my Struts Actions, I have created a class called BaseAction that implements cache control:

response.setHeader("Cache-Control","no-cache");
response.setHeader("Cache-Control","no-store");
response.setDateHeader("Expires", 0);
response.setHeader("Pragma", "no-cache");

All my Struts Actions extend my BaseAction class. The problem is that, when I click the back button, IE shows the error page "The page cannot be displayed".

The problem does not occur if I disable the first two headers:

//response.setHeader("Cache-Control","no-cache");
//response.setHeader("Cache-Control","no-store");

In order to see what IE does when I click the back button, I have made a snoop of tcp/http traffic. IE does not send anything (neither a bite!) to the server when I click the back button.
Furthermore, the problem does not occur when using Firefox 1.0.3 (it shows the message "the page contains POST data - do you want to resend data?").

Can anybody help me please? Thanks in advance.
David
