I need to read Html source of a Web From at Server -- Copy the whole html source code before actually rendering it

<%@ _Page Language="C#" _AutoEventWireup="true" _CodeFile="RenderPageToHtml.aspx.cs" _Inherits="RenderPageToHtml" _Trace="true" %>

<_head runat="server"> <_title>Untitled Page<_body>

<_form id="form1" _runat="server"> <_div> <_asp:_textbox id="TextBox1" runat="server" height="414px" textmode="MultiLine" width="198px"> <_asp:_button id="Button1" runat="server" text="Button"> <_asp:_linkbutton id="LinkButton1" runat="server">LinkButton using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class RenderPageToHtml : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { if (Session["text"] != null) { TextBox1.Text = Session["text"].ToString(); } } protected override void Render(HtmlTextWriter writer) { System.IO.MemoryStream mem = new System.IO.MemoryStream(); System.IO.StreamWriter twr = new System.IO.StreamWriter(mem); System.Web.UI.HtmlTextWriter myWriter = new HtmlTextWriter(twr); base.Render(myWriter);
myWriter.Flush(); myWriter.Dispose();
System.IO.StreamReader strmRdr = new System.IO.StreamReader(mem); strmRdr.BaseStream.Position = 0; string pageContent = strmRdr.ReadToEnd(); strmRdr.Dispose(); mem.Dispose(); Session["text"] = pageContent; writer.Write(pageContent); }}
