How to build a distributed session subsystem of. NET based on MongoDB

Taobao has her own distributed session framework, the. NET camp can not lag behind, did a mongodb based on the support of up to 26 MongoDB distributed session framework.

First look at the configuration file:

<?xml version="1.0" encoding="utf-8" ?>
<MongoDBSession>
  <DbName>SessionDB</DbName>
  <IdentityMap 

Identity="A">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="B">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="C">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="D">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="E">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="F">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="G">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="H">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="I">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="J">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="K">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="L">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="M">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="N">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="O">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="P">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="Q">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="R">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="S">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="T">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="U">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="V">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="W">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="X">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="Y">mongodb://localhost</IdentityMap>
  <IdentityMap 

Identity="Z">mongodb://localhost</IdentityMap>
</MongoDBSession>

From identity A to Z, the default is divided into 26 maps, the specific C # application code:

protected void btnTest_Click (object sender, EventArgs e)
        {
            session["A"] = DateTime.Now;
            session["B"] = 1111111111111;
            session["C"] = "fffffffffffffff";
        }
    
        protected void Btngetsession_click (object sender, EventArgs e)
        {
            Response.Write (session["A"]. ToString ());
            Response.Write ("<br/>");
            Response.Write (session["B"). ToString ());
            Response.Write ("<br/>");
            Response.Write (session["C"]. ToString ());
        }
        protected void Btnabandon_click (object sender, EventArgs e)
        {
            Session.Abandon ();
        }
