How to refresh the main page in the ProcessRequest method of a generic handler?

I'm developing a webform application that uses a generic handler to receive HTTP POST and retrieve data from it in order to write them into database and then display it in the GridView control of the main page. I want to make the main page been automatically refreshed once the generic handler receives a HTTP Post, but it can't and I have to click the refresh button on the browser to update its data content. I searched online about the code of refreshing pages and tried something like this:

public void ProcessRequest(HttpContext context)
    {
        //Parse and process data from received HTTP Post
        context.Response.Redirect("~/Main.aspx");
    }

But it doesn't work. Can anyone solve my question?

A handler can't force a refresh of the page that calls it. You need to update the code that calls the handler to issue a refresh (it can issue a redirect to itself) after the handler has called. The refresh can't be done from the handler itself.

Actually I haven't wrote any code to call the handler. It's automatically invoked by the server once a new HTTP Post is sent to there.

Try adding a "cache-buster" querystring variable to the URL:

C#

context.Response.Redirect("~/Main.aspx?dummy=" + DateTime.UtcNow.Ticks);
