hi,
Does anybody know how to detect when the user click on the back button to go back to the previous page?
Or a way to refresh a jsp page whenever it's loaded?

Thank you. :)

Add these four lines at the top of the JSP:

response.setHeader( "Expires", "Sat, 6 May 1995 12:00:00 GMT" );
     
// set standard HTTP/1.1 no-cache headers
response.setHeader( "Cache-Control", "no-store, no-cache, must-revalidate" );

// set IE extended HTTP/1.1 no-cache headers
response.addHeader( "Cache-Control", "post-check=0, pre-check=0" );

// set standard HTTP/1.0 no-cache header
response.setHeader( "Pragma", "no-cache" );

That *should* force the user agent to reload the page when it is hit.

Do you have this in your <HEAD> part of HTML coding...

<meta http-equiv="pragma" content="no-cache"/>
<meta http-equiv="expires" content="0"/>
<meta http-equiv="cache-control" content="no-cache"/>

You can use a META tag with an HTTP-EQUIV attribute to control the action of browsers, by setting the HTTP headers. The "Refresh" value can be used to specify a delay in seconds before the browser automatically reloads the document. Optionally, you can also specify an alternative URL to load.

For example, the following tag loads the page yours.jsp after 5 seconds.

<META HTTP-EQUIV="Refresh" CONTENT="5;URL=yours.jsp">

A fine tutorial for the META-Tag: HTTP-EQUIV:

We work together.  Our pages use a header and footer that contain opening and closing tags for <html> and <body>, this is used to create consistency.  I had a similiar issue and I found solutions to refreshing in meta and body tags which unfortunately we are not able to implement.  I didn't find anything suggesting we could detect when the user had clicked the back button on internet explorer but would be useful to know.

What does not work?  
When you press the back button, does the server not get hit?
What browser are you using?
