Storage of client session Status in ASP. NET
In our previous session model introduction, we can find that the session status should be stored in two places: client and server. The client is only responsible for saving the sessionid of the corresponding website, while other session information is stored on the server. In ASP, the sessionid of the client is actually stored as a cookie. If the user chooses to disable cookies in the browser settings, then he will not be able to enjoy the convenience of the session, or even access some websites. To solve the above problems, the session information storage methods of the client in ASP. NET are divided into cookie and cookieless.
In ASP. NET, by default, session information is stored on the client using cookies. If you want to use cookieless on the client to store session information, the method is as follows:
Find the current Web Application Program Open the Web. config file and find the following section:
<Sessionstate
Mode = "inproc"
Stateconnectionstring = "TCPIP = 127.0.0.1: 42424"
Sqlconnectionstring = "Data Source = 127.0.0.1; trusted_connection = yes"
Cookieless = "false"
Timeout = "20"
/>
In this section, cookieless = "false" is changed to cookieless = "true". In this way, the session information of the client is no longer stored using cookies, but stored through URLs. Close the current IE, open a new IE, and re-access the Web application, you will see something similar to the following:
Http: // localhost/mytestapplication/(ulqsek45heu3ic2a5zgdl245)/default. aspx indicates the session ID of the client. Note that this information is automatically added by IIS and does not affect the normal connection.
Storage of server session Status in ASP. NET
Preparations
To better experience the experiment, you can create a page called sessionstate. aspx and Code Add to <body> </body>.
<Scriptrunat = "server">
Sub session_add (sender as object, e as eventargs)
Session ("mysession") = text1.value
Span1.innerhtml = "session data updated! <P> your session contains: <font color = Red> "&\
Session ("mysession"). tostring () & "</font>"
End sub
Sub checksession (sender as object, EAS eventargs)
If (Session ("mysession") is nothing) then
Span1.innerhtml = "nothing, session data lost! "
Else
Span1.innerhtml = "your session contains: <font color = Red> "&\
Session ("mysession"). tostring () & "</font>"
End if
End sub
</SCRIPT>
<Formrunat = "server" id = "form2">
<Inputid = "text1" type = "text" runat = "server" name = "text1">
<Inputtype = "Submit" runat = "server" onserverclick = "session_add"
Value = "add to session state" id = "submit1" name = "submit1">
<Inputtype = "Submit" runat = "server" onserverclick = "checksession"
Value = "View session state" id = "submit2" name = "submit2">
</Form>
<Hrsize = "1">
<Fontsize = "6"> <spanid = "span1" runat = "server"/> </font>
This sessionstate. ASPX page can be used to test whether session information is lost on the current server.
Store Server session information in the process
Let's go back to the section in the web. config file:
<Sessionstate
Mode = "inproc"
Stateconnectionstring = "TCPIP = 127.0.0.1: 42424"
Sqlconnectionstring = "Data Source = 127.0.0.1; trusted_connection = yes"
Cookieless = "false"
Timeout = "20"
/>
When the mode value is inproc, it indicates that the server is using this mode.
