ASP.NET中解决跨子域的Session共享 demo 下载
多个站点间session共享,例如:1.1.com;2.1.com;3.1.com 等类似站点之间的session共享。找了很久的资料,今天终于解决了!点击下载demo
具体配置:
1.在项目中添加引用 WebLibrary.dll (demo 已经包含 WebLibrary.dll文件)
2.在 web.config 的 appsetting 节点中添加主站域名。
例如:<add key="RootDomain" value=".你的域名.com"/> 注意:域名前面的那个点不要掉。
3.在 web.config 的 system.web 节点中添加
<httpModules>
<add name="CrossDomainCookieModule" type="WebLibrary.CrossDomainCookie, WebLibrary"/>
</httpModules>
4.在web.config的system.web节点中修改session存储方式为stateserver
<sessionState mode="StateServer" stateConnectionString="tcpip=服务器ip地址:42424" timeout="30" />
5.在web.config的system.webServer几点中添加
<modules>
<add name="CrossDomainCookieModule" preCondition="managedHandler" type="WebLibrary.CrossDomainCookie, WebLibrary"/>
</modules>
注意点:
1.服务器 aspnet_state 服务开启。
2. 修改服务器 注册表“HKEY_LOCAL_MACHINE/SYSTEM/ControlSett001/Services/aspnet_state/Parameters“修改AllowRemoteConnection=1,Port=42424s
