Many people search for this. Note I have XML serialized the object because if you do binary serialization, if there are breaking changes in the class, then it will not de-serialize. To compress, do this: CompressionOutput output = new CompressionOutput();             byte[] xmlBytes = Encoding.UTF8.GetBytes(largeString);             MemoryStream memoryStream = new MemoryStream();             try             {                 using (GZipStream zipStream = new GZipStream(memoryStream, CompressionMode.Compress))                 {                     try                     {                         zipStream.Write(xmlBytes, 0, xmlBytes.Length);                     }                     finally                     {                         zipStream.Flush();                         zipStream.Close();                     }                 }                 byte[] compressedData = memoryStream.ToArray();                               if (compressedData.Length < x

I spent a few days puzzling over this without luck then it hit me! Just create a dummy page which has the Google Analytics JS embedded in it, in the OnInit of your RSS feed, use the System.Net.WebClient to load the dummy ASPX page dynamically: protected override void OnInit(EventArgs e)     {         base.OnInit(e);         try         {             using (WebClient objWebClient = new WebClient())             {                 objWebClient.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");                 Stream data = objWebClient.OpenRead(BASE_URL + "DummyPage.aspx");             }         }         catch { }     }

I recently had a chat with a friend who thought that if we do ADO.NET transactions, those would be distributed transactions. That is obviously incorrect, so I thought let me clarify for everyone here. A Distributed transaction is a transaction which involves multiple resource managers. These could be MSMQ and SQL Server or 2 SQL Server Instances, or SQL Server and Oracle.. etc. Each of these resource managers support transactions within themselves, using that does not mean you are creating a Distributed Transaction, which is actually much more expensive, but necessary in some scenarios where you need transactional integrity. To implement this using .NET, you have to register the assembly with COM+ and use some attributes. It is very interesting and Juval Lowy had written an interesting book on this subject quite some time ago, which also discusses Queued Components interestingly...
