1.Using the standard HTML Mewta tag 'Refresh'. This tag specifies a delay before the browserautomatically reloads the page. The delay is specified in seconds. You can specify a URL also to reload. If you do not specify a URL, it will relaod the same page after the interval.
<head><meta http-equiv="refresh" content="10" >
</head> 2. Response.AppendHeader("Refresh", "10; URL=http://www.dotnetspider.com")
3.If you are only trying to refresh your page once, this is something better handled on the client side. E.g.:
<script>
function refresh() { window.location.reload(); } </script> <button οnclick='refresh();'>Refresh the page once</button>
