asp.net Hessian 服务的注册

Hessian服务端实现了IHttpHandle,

默认情况下是在Web.Config中的handles接点中注册,这样当有 很多实现时比较麻烦

这个时候可以实现IHttpHandleFactory注册到Web.Config中,在Factory中实现对具体服务的实例化,

另外也可以使用RouteTable方式,自己实现以个IRouteHandle,注册到RouteTable的Routes表中,

需要注意的是,RouteTable方式在asp.net管线的位置靠前,会屏蔽掉后面的IHttphandle方式.

另外注意在IIS 6中,需要在IIS中添加对.hessian的印射(取消确认文件存在选择),而在IIS7.0中需要在Web.Config的Web.Server配置节里注册HttpHandle或HttpHandleFactory-如果采用的不是RouteTable方式的话
