Googled around a little bit and found this: http://www.i18nguy.com/markup/metatags.html

Looks like 

   <meta http-equiv="Cache-Control"content="no-cache">

might work.

Thanks for your reply, but

I also tried with these two line also

<meta http-equiv="Expires" content="-1"> 

<meta http-equiv="cache-control" content="no-cache, no store,must-revalidate"/>

it does not work. Any answer will be accepted.

I can not find any information about meta element pragmas in the documentation of the meta element. I also cannot find information about meta element pragmas in the html5 specification. Maybe this is no longer supported?
See:

Maybe you can try to use real headers instead.
