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>

    HTML web page ouput:

    Sess1
    Sess2
    Sess3>

    1 = An Array
    2 = An Object
    3 = Astrvalue

Session.StaticObjects Collection

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

Syntax:

Session.StaticObjects( Key)

 Or in an ASP file. Imply

<% Session.StaticObjects( Key) %>

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">
