HTTP GET请求结构

Question

考虑以下超链接：

<a href="http://www.cs.rutgers.edu/∼shklar/"> 

什么HTTP/1.0请求将得到由浏览器提交的？ 浏览器会提交什么HTTP/1.1请求？

如果浏览器被配置为 联系HTTP代理，这些请求是否会改变？如果是，如何？

Answer 1

虽然您可以使用tcpdump转储实际的网络流量，但curl确实更方便从命令行测试HTTP对话。

的HTTP/1.0请求：

curl -v -0 http://www.cs.rutgers.edu/∼shklar/ 
* About to connect() to www.cs.rutgers.edu port 80 (#0) 
* Trying 128.6.4.24... 
* connected 
* Connected to www.cs.rutgers.edu (128.6.4.24) port 80 (#0) 
> GET /∼shklar/ HTTP/1.0 
> User-Agent: curl/7.24.0 (x86_64-apple-darwin12.0) libcurl/7.24.0 OpenSSL/0.9.8r zlib/1.2.5 
> Host: www.cs.rutgers.edu 
> Accept: */* 
> 
< HTTP/1.1 404 Not Found 
< Date: Wed, 31 Oct 2012 17:57:31 GMT 
< Server: Apache/1.3.26 (Unix) 
< Content-Type: text/html; charset=iso-8859-1 
< Connection: close 

的HTTP/1.1请求：

curl -v http://www.cs.rutgers.edu/∼shklar/ 
* About to connect() to www.cs.rutgers.edu port 80 (#0) 
* Trying 128.6.4.24... 
* connected 
* Connected to www.cs.rutgers.edu (128.6.4.24) port 80 (#0) 
> GET /∼shklar/ HTTP/1.1 
> User-Agent: curl/7.24.0 (x86_64-apple-darwin12.0) libcurl/7.24.0 OpenSSL/0.9.8r zlib/1.2.5 
> Host: www.cs.rutgers.edu 
> Accept: */*

< HTTP/1.1 404 Not Found

< Content-Type: text/html; charset=iso-8859-1 
< Transfer-Encoding: chunked 

使用-x (or --proxy) <[protocol://][user@password]proxyhost[:port]>开关使用代理和查看结果。
