Session Object

One of the key functions of Session Object is the session data control on the server.

Session.Contents Collection

Session.Content Collection adds or sets the value of an item of the Contents collection of Session object through script commands for a session.

Syntax:

Session.Contents( Key)

 Or in an ASP file.  Imply

<% Session.Contents( Key) %>

Parameters:

Key

The parameter "Key" is used to specify the name of the item to retrieve.

Remarks:

The Contents collection contains only the list of items that have been declared in session scope using script commands not the <OBJECT> tags. Therefore both an session declaration and objects created by using the Server.CreateObject are contained in the Contents Collection

The Contents collection can be used to obtain the list of items or a particular item that have been declared in application scope.

But the items in the Contents collection can only be removed from the collection by using the Remove and RemoveAll methods.

The Contents Collection is in the form of collection, the values of the keys of the cotents collection should be retrieved using a for each element loop in order to get the name of the element. Or using a for index loop is the key is predetermined.

Examples:

• Use Session.Contents to retrieve the value of item

  ASP script command:

  <%
  Dim StrAry(1)
  StrAry(0)="One"
  StrAry(1)="Two"
  Set Objconn=Server.CreateObject("adodb.connection")
  Session.Contents.Item("Sess1") = StrAry
  Set Session.Contents.Item("Sess2") = Objconn
  Session.Contents.Item("Sess3") ="Astrvalue"
  For Each element in Session.Contents
  Response.write element & "<br>"
  Next
  Response.write "<br>"
  For itemno = 1 to Session.Contents.Count
  Response.Write CStr(itemno) & " = " 
  If IsObject(Session.Contents(itemno)) then
  Response.Write "An Object"  &  "<br>"
  end if
  If IsArray(Session.Contents(itemno)) then
  Response.Write "An Array"  &  "<br>"
  end if
  If IsNumeric(Session.Contents(itemno)) then
      Response.Write "An Object"  &  "<br>"
  end if
  If Not IsNull(Session.Contents(itemno)) or _
  Not IsEmpty(Session.Contents(itemno)) then
      Response.Write Session.Contents(itemno) &  "<br>"
  end if
  Next
  %>
  

  HTTP response output:

  Sess1<br>
  Sess2<br>
  Sess3<br>
  <br>
  1 = An Array<br>
  2 = An Object<br>
  3 = Astrvalue<br>

Session.StaticObjects Collection

Session.StaticObjects Collection collects all objects added to the current session through the <OBJECT> tag within the Session scope

Parameters:

Key

The parameter "Key" is used to specify the name of the item to retrieve.

Remarks:

The StaticObjects collection contains only the list of items that have been declared in session scope using <OBJECT> tags not the script commands. Therefore both an application declaration and objects created by using the Server.CreateObject are contained in the Contents Collection not in StaticObject collection.

The StaticObjects collection can be used to obtain the list of items or a particular item that have been declared in session scope.

The StaticObjects Collection is in the form of collection, the values of the keys of the StaticObjects  collection should be retrieved using a for each element loop in order to get the name of the element.

  <object id="ExAdRot" runat="server"
  progid="MSWC.AdRotator" scope="session">
