In this post I will show you how to compress http response in asp.net for improving performance.
Before going into details let's create a simple website with single page Default.aspx and add following code into it
Default.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:GridView ID="grdPerson" runat="server"> </asp:GridView> </div> </form> </body> </html>Default.aspx.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { grdPerson.DataSource = Person.Persons; grdPerson.DataBind(); } } } [Serializable] public class Person { public string FirstName { get; set; } public string LastName { get; set; } public int Phone { get; set; } public string Email { get; set; } public static List<Person> Persons { get { return new List<Person>() { new Person(){FirstName="Santosh",LastName="Singh",Phone=1213123,Email="santosh@gmail.com"}, new Person(){FirstName="Ashok",LastName="Singh",Phone=1213123,Email="ashok@gmail.com"}, new Person(){FirstName="Bill",LastName="Gates",Phone=1213123,Email="bill@gmail.com"}, }; } } public override string ToString() { return string.Format(@"FirstName {0} & LastName {1} Phone {2} Email {3}", this.FirstName, this.LastName, this.Phone, this.Email); } }Now,press F5 and see the response result in FireBug.You will see the response result something like below
void Application_BeginRequest(object sender, EventArgs e) { }Inside it paste the following code and see the result in FireBug
void Application_BeginRequest(object sender, EventArgs e) { HttpContext incoming = HttpContext.Current; string oldpath = incoming.Request.Path.ToLower(); incoming.Response.Filter = new System.IO.Compression.GZipStream(incoming.Response.Filter, System.IO.Compression.CompressionMode.Compress); HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip"); HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true; }
