page expires when back button is clicked

[n0vembr]

hello..

can anybody tell me why my browser expires when the "back" button is clicked ??

here's a part of the code ...it can successfully forward the page to an action (that has a different dataform) but when the back button is clicked the page expires...

            <bean:define id="param1" name="detail" property="ccid_flex"/>
            <%

                java.util.HashMap params = new java.util.HashMap();
                    params.put("voData.code_combination_id", param1);
                    params.put("voData.inquiry_type","0");
                    params.put("voData.cuenta_code", param1);
                    pageContext.setAttribute("paramsName", params);

            %>

            <html:link page="/RetrieveDetailInquiryTransaction.do" name="paramsName" scope="page" >
               <bean:write name="detail" property="ccid_flex"/>
            </html:link>

What's the generated code of this snippet? More importantly, how do you reach that page? Somewhere in there are POST variables, that's what expires.
