在兩個應用的web.config 中 system.web 節點 設定使用SQLServer儲存Session

1 <sessionState mode="SQLServer" cookieless="false" timeout="1000" sqlConnectionString="Data Source=伺服器IP;Persist Security Info=True;User ID=sa;password=123456"/>

然後到資料庫伺服器中 開啟ASPState 資料庫

執行下面的語句

USE [ASPState]
GO
/****** Object:  StoredProcedure [dbo].[TempGetAppID]    Script Date: 11/21/2020 10:19:18 *****
 
*/
/*
Session 共享方案
在IIS中找到站點的ID
然後在 tempdb.dbo.ASPStateTempApplications 表中找到站點的 appName  以及它的父級站點

將查詢到的 appName 賦值給下面的 @appPMame

這樣就可以在這個站點下的所有 子應用都共享Session

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER OFF
GO

    ALTER PROCEDURE [dbo].[TempGetAppID]
    @appName    tAppName,
    @appId      int OUTPUT
    
 
AS
    declare @appPMame varchar(100)='/lm/w3svc/90/root' --站點父級APPName

    --if @appName='/lm/w3svc/90/root/name'    --具體子應用程式共享
    if CHARINDEX(@appPMame, @appName )>0        --所有子應用程式共享
    begin
        select @appId= appid FROM [tempdb].dbo.ASPStateTempApplications where
 
 AppName=@appPMame
    end
    if @appId is null
    begin
        SELECT top 1  @appId = AppId
        FROM [tempdb].dbo.ASPStateTempApplications
        WHERE AppName = @appName
    end
    IF @appId IS NULL BEGIN

            INSERT [tempdb].dbo.ASPStateTempApplications

                RAISERROR('SQL session state fatal error: hash-code collision between applications ''%s'' and ''%s''. Please rename the 1st application to resolve the problem.', 
                            18, 1, @appName, @dupApp)
            END
        END

        COMMIT
    END

    RETURN 0   
    

執行成功後，建議重啟資料庫與IIS，清空一下Session
