How to force <href> tag to get jsp page from the server not from the cache? eg.,
<a href="LogoutVerification.jsp" target="rightframe"> <b>Logout</b>

In the JSP, put the anti-cache code.
You have to set the anti-cache code in the response headers like this
response.setHeader("Cache-Control","max-age=0");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
The first line is used to for HTTP 1.1 protocol
the second line is used for HTTP 1.0.
The third line will prevent caching at the proxy servers.
