telnet模拟http訪问

HTTP协议经常使用的无非就那么几个命令

GET

HEAD

PUT

POST


此处简单说下http的GET和HEAD

举两个简单的样例:

GET的样例

telnet serverip 80

GET http://www.aaa.com/aaa.html  //输入get命令和get的url

                                     HTTP/1.0 200 OK
Date: Thu, 24 Apr 2014 01:19:11 GMT
X-Powered-By: ASP.NET   yltv
X-AspNet-Version: 2.0.50727
Content-Type: text/html; charset=gb2312
Content-Length: 28309
X-Cache: HIT from cache121.aaa.com
Connection: close


<h1>john_test page!!!</h1>

失去了跟主机的连接。


HEAD的样例 查看响应的HTTP头信息在win下可取代CURL 命令的-I參数 

telnet serverip 80

GET http://www.aaa.com/aaa.html  //输入get命令和get的url

                                     HTTP/1.0 200 OK
Date: Thu, 24 Apr 2014 01:19:11 GMT
X-Powered-By: ASP.NET   yltv
X-AspNet-Version: 2.0.50727
Content-Type: text/html; charset=gb2312
Content-Length: 28309
X-Cache: HIT from cache121.aaa.com
Connection: close


失去了跟主机的连接。


就像squid有个清缓存的http指令。PUGRE

假设项清除某个页面的缓存就能够telnet到此squidserver的80port

然后运行PUGRE http://host/url 这样就能够pugre缓存了

但前提是squid的acl同意!


原来HTTP协议就是如此的简单!!!
