If you have requirement such as you want to refresh your page after every few seconds or minutes, you are reading right blog. I found it very easy to implement. Please go through below example and you will get the exact idea.
Server side code
protected void Page_Load(object sender, EventArgs e)
{
Response.AddHeader("refresh", "5");
}
Client side code
<html>
<head>
<script language="javascript" type="text/javascript">
function fn()
{
var currentTime = new Date()
var hours = currentTime.getHours()
var minutes = currentTime.getMinutes()
var seconds = currentTime.getSeconds()
if (minutes < 10){
minutes = "0" + minutes
}
if (seconds < 10){
seconds = "0" + seconds
}
document.getElementById("div1").innerHTML = hours + ":" + minutes + ":" + seconds
}
</script>
</head>
<body onload="fn();">
<div>
<div id="div1" />
</div>
</body>
</html>
In the above example I have implemented client side watch, which refreshes every five seconds. The only line of code required to write to submit the page is Response.AddHeader("refresh", "5");, other is just custom logic.
happy coding... :)

Relative path issue with client tags ( ~ is not working )
You can continue using a client tag such as <img>, <link>, etc. with the "~" tilde with below solution.
You just need to use the System.Web.VirtualPathUtility.ToAbsolute("~") method to convert the ~ to the Application Path.
So, if your file is located at "~/images/default.jpg" and you need to specify this path in a client tag like <img>, ASP.NET would not allow you to use this path unless you use a Server Control like <asp:Image>.
To continue using the client tag you can use:
<img src="<%=System.Web.VirtualPathUtility.ToAbsolute("~")%>/images/ default.jpg" />
This would be resolved to "/MyApplication/images/default.jpg" where the first forward slash (/) stands for the WebSite root. Thus, the tilde "~" is effectively resolved to "/MyApplication"
Alternatively, Control.ResolveClientUrl can be used. For example,
<img src='<%= ResolveClientUrl("~/images/default.jpg")%>' />
