IHttpHandlerFactory的使用测试
仿照msdn写了一个接管http请求的类,对于aspx文件,可以正常实现功能,但是对于图片文件,比如
*.jpg却不行,找了一些资料也没搞清楚,cs文件和config文件如下:
搞定了，在IIS中指定对.jpg文件的映射
[D:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll]

if("get" == context.Request.RequestType.ToLower())
{
handlerToReturn = new HandlerImg();
}
else if("post" == context.Request.RequestType.ToLower())
{
handlerToReturn = new HandlerImg();

return handlerToReturn;
