如何判断我的服务器是否提供GZipped内容？ [英] How can I tell if my server is serving GZipped content?

问题描述

我在NGinx服务器上有一个webapp。我在conf文件中设置 gzip在，现在我想看看它是否工作。 YSlow说不是，但是6个网站中有5个做测试说这是。

I have a webapp on a NGinx server. I set gzip on in the conf file and now I'm trying to see if it works. YSlow says it's not, but 5 out of 6 websites that do the test say it is. How can I get a definite answer on this and why is there a difference in the results?

推荐答案

这看起来像一个可能的答案是，不出意料， curl ：

It looks like one possible answer is, unsurprisingly, curl:

$ curl http://example.com/ --silent --write-out "%{size_download}\n" --output /dev/null
31032
$ curl http://example.com/ --silent -H "Accept-Encoding: gzip,deflate" --write-out "%{size_download}\n" --output /dev/null
2553

$ b b

在第二种情况下，客户端告诉服务器它支持内容编码，你可以看到响应确实更短，压缩​​。

In the second case the client tells the server that it supports content encoding and you can see that the response was indeed shorter, compressed.
