有时在管理一个网站时,事情会被搞得一团糟。你可能会删除一些陈旧的内容,用重定向到其他页面来代替。后来,在做了其他改动后,你发现一些网页变得完全无法访问了。你可能会在浏览器中看到一个错误:“该页面没有正确重定向”,并建议你检查你的 cookie。 Redirect loop example in Firefox 调试这种情况的一个方法是使用 wget 命令行程序,使用 -S 选项来显示所有的服务器响应。当使用 wget 进行调试时,我也喜欢使用 -O 选项将输出保存到一些临时文件中,以备以后需要查看其内容。 - $ wget -O /tmp/test.html -S http://10.0.0.11/announce/
