WCF服务中操作FormsAuthentication的Cookie

在asp.net 应用程序和WCF服务之间共享FormsAuthentication，默认是不支持的，设置一下非常的简单，只需要两步就可以了：

1、在web.config的system.serviceModel增加一个配置：

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>

2、为WCF打上标签

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

这样在WCF服务上就可以操作cookie了。
