Thanks for quick reply Brian.!
I tried adding new timestamp as parameters which generates new number
everytime I visit the page.
Even added those headers setting for no cache...
<meta http-equiv="Cache-Control" content="no-store"/>
<meta http-equiv="Pragma" content="no-cache"/>
<meta http-equiv="Expires" content="0"/>
Still it is not getting updated.
