http://www.adleradelboden.ch/webcam/Adler000.JPG的响应标头：

HTTP/1.1 200 OK
Content-Length: 59080
Content-Type: image/jpeg
Last-Modified: Sun, 09 Oct 2011 09:32:42 GMT
Accept-Ranges: bytes

有Last-Modified标头。

您还没有告诉我们您如何获得此信息。但是通过查看您收到的标头，会有Location标头，因此您的请求会被重定向。您应该将curl设置为跟随位置

在IIS的情况下检查从远程文件的标题中的最后修改
