1.使用Get请求

说明如下：
在AServlet中new一个Cookie让客户端保存
在BServlet中显示在AServlet中创建的cookie
1.1在浏览器中直接输入URL：http://localhost:8080/Demo2/AServlet
的请求头

GET /Demo2/AServlet HTTP/1.1Host: localhost:8080Connection: keep-aliveAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36Accept-Encoding: gzip, deflate, sdchAccept-Language: zh-CN,zh;q=0.8,en;q=0.6

1.2在浏览器中直接输入URL：http://localhost:8080/Demo2/BServlet

的请求头

GET /Demo2/servlet/BServlet HTTP/1.1Host: localhost:8080Connection: keep-aliveAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36Accept-Encoding: gzip, deflate, sdchAccept-Language: zh-CN,zh;q=0.8,en;q=0.6*************************************************Cookie: uuid=08ee7eda-9cd9-49dd-8630-7a4d16fd494e*************************************************

2.使用Post请求

说明如下：
在index.jsp中先后分别请求AServlet和BServlet
index.jsp

<body>    <form action="/Demo2/AServlet" method="post">        <input type="submit" value="post-AServlet"/>    </form>    <form action="/Demo2/BServlet" method="post">        <input type="submit" value="post-BServlet"/>    </form>  </body>

2.1请求AServlet

POST /Demo2/AServlet HTTP/1.1Host: localhost:8080Connection: keep-aliveContent-Length: 0Cache-Control: max-age=0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8Origin: http://localhost:8080Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36Content-Type: application/x-www-form-urlencodedReferer: http://localhost:8080/Demo2/index.jspAccept-Encoding: gzip, deflateAccept-Language: zh-CN,zh;q=0.8,en;q=0.6******************************************************Cookie: JSESSIONID=D4288C7911533D4275DDE31AE33B961C******************************************************

2.2请求BServlet

POST /Demo2/BServlet HTTP/1.1Host: localhost:8080Connection: keep-aliveContent-Length: 0Cache-Control: max-age=0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8Origin: http://localhost:8080Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36Content-Type: application/x-www-form-urlencodedReferer: http://localhost:8080/Demo2/index.jspAccept-Encoding: gzip, deflateAccept-Language: zh-CN,zh;q=0.8,en;q=0.6********************************************************Cookie: JSESSIONID=D4288C7911533D4275DDE31AE33B961C; uuid=743468ab-c83d-4298-b127-477fa6194140*********************************************************POST /Demo2/BServlet HTTP/1.1Host: localhost:8080Connection: keep-aliveContent-Length: 0Cache-Control: max-age=0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8Origin: http://localhost:8080Upgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36Content-Type: application/x-www-form-urlencodedReferer: http://localhost:8080/Demo2/index.jspAccept-Encoding: gzip, deflateAccept-Language: zh-CN,zh;q=0.8,en;q=0.6*****************************************************Cookie: JSESSIONID=D4288C7911533D4275DDE31AE33B961C; uuid=743468ab-c83d-4298-b127-477fa6194140*****************************************************

可以发现使用get和post所请求的头的Cookie头不一样，get请求一开始没有cookie头字段而post请求始终有cookie头字段其cookie为JSESSIONID

先把这个问题记着，搞懂了，分析一下~
