I找不到内容编码：gzip




但如果我使用chrome或其他浏览器访问www.elong.com，我可以看到响应头包含 Content-编码：gzip

I cannot find Content-Encoding: gzip


But If I use chrome or some other browser to visit www.elong.com , I can see the response header contains Content-Encoding: gzip

这是wget或其他原因的错误吗？





thx

Is it a bug of wget or some other reason?


thx

推荐答案

解决了！ Wget版本太旧了！



真正的原因是老版本wget使用HTTP 1.0而较新版本使用HTTP 1.1

Solved! Wget version is too old!

The real reason is old version wget uses HTTP 1.0 and newer version uses HTTP 1.1
