Reload in Firefox

  • hi, now i m using 2.0-RC1 (i386) built on Fri Mar 25 20:35:06 EDT 2011 .

    In my captive portal page i have a simple chat with flat txt file database, when someone submit a comment , the page will reload with the new data ,

    and will auto refresh and reload with new data in 60 sec . Im using  "    " in my html iframe  . Its works

    flawlessly in Pf 1.2.3 with all internet bowser . Now its only work in Internet Explorer , not with Firefox and google Chrome. And  i  have  to clear the

    cache in Chrome or Firefox  and then press F5 to reload the page . Is there any other code other than meta tags or header(….. that i can use .
