How to Auto Refresh / Re Load Page

Sometimes we need a page which shows real time date e.g. Stock exchange, cricket match, etc. To add auto refresh / re load you need to add the following meta tag in your markup's head section.
<meta http-equiv="refresh" content="600">

If you want to add this from code behing, then you can add it like this:-
protected void Page_Load(object sender, EventArgs e)
HtmlMeta hmRefresh = new HtmlMeta();
hmRefresh.HttpEquiv = "Refresh";
hmRefresh.Content = "10";//Time in seconds
