IE Browser back button goes to two pages back
I am not using JSPs, using a servlet ABSServlet to display the search page, after entering the search criteris I'm displaying a report page. The report page has a button 'Save As Excel' which open the report in the Excel form. When I click on this button browser asks 'Open' or 'Save'. I clicked on 'Open'. It open the report in excel form in the same page. Now if I press the IE Browser back button it takes me to the Search page instead of the report page.
Ideally it should go back to the Report page(preiosu page) if I click the back button and not to the previous to previous page. Can someone help?

You cannot (practically) modify the function of the browser's back button...
You can patch it though.
Put in the intermediate (search) page something like
<script language="Javascript"><!--
function sendBack()
{
wherefrom=history.forward(1); //only valid if the back button has been used. otherwise null
length=wherefrom.length();//length of 'forward page's url'
if (history.forward(1).substring(length-4)==".xls") //the back button has been press on a url ending .xls - back from a spreadsheet
{
location.href=history.back(1); //go back once more from here
}
else
{
//this is if the back button was not used or if back button was used from a page that is not an excel spreadsheet;
//if you write nothing here, the page just display as though this function were not here
}
}
//--></script>
<body onload="sendback()">
Not really a Java solution, but should work.
