Hi,

As we all know the world of the Blogs work on the ping services. Once we update our blog with new posts we need to update the other sources that our blog has been updated. We should ping to the sources whenever we create or update our post.

Pings can be done both manually and programmatically. Many site provide free ping services for with a ping interface like http://ping.in/, http://pingoat.com etc. You enter your URL and and the feed title and they will ping all the ping server listed.

We can also ping programmatically. Programmatic ping is done through XMP-RPC Procedure, through which we send xml over the http request. The XML contains information of your feed and the URL to which you send the request is called the endpoint

Here is an example that I found that uses the xmlRpc Library from the cook computing.

All we need to do is call one line of code once we have updated the site.

BlogUpdateResponse result =
     WeblogsRPC.Ping("VikramLakhotia.com", "http://www.VikramLakhotia.com");

Here is the source code for the same.

using System;
using CookComputing.XmlRpc;

namespace VikramLakhotia
{
    public class WeblogsRPC
    {
        public static BlogUpdateResponse Ping(string weblogName, string weblogUrl)
        {
            IWeblogsUpdate proxy = (IWeblogsUpdate)XmlRpcProxyGen.Create(typeof(IWeblogsUpdate));
            return proxy.ping(weblogName, weblogUrl);
        }
    }

    public struct BlogUpdateResponse
    {
        public bool IsError;
        public string strMessage;
    }

Thanks
Vikram
