CAS協議的抓包分析

近日有朋友想了解一下CAS的協議的HTTP流程，我之前抓過包，現在貼出來，希望對那位朋友有所幫助。
CAS Server:caserver:7002
Tomcat APP應用:appserver01:8080
訪問 appserver01:8080 的 SessionExample

GET /servlets-examples/servlet/SessionExample HTTP/1.1

Accept: */*

Accept-Language: zh-cn,en;q=0.8,zh;q=0.5,zh-tw;q=0.3

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Maxthon; .NET CLR 2.0.50215)

Host: appserver01:8080

Connection: Keep-Alive

?

appserver01:8080 引導我到 casserver:7002 進行認證 , 注意 ,Service=SessionExmaple 的 URL

HTTP/1.1 302 Moved Temporarily

Set-Cookie: JSESSIONID=22311DC79C684A911EEEBC3F0FBDB136; Path=/servlets-examples

Location: https://casserver:7002/cas/login?service=http%3A%2F%2Fappserver01%3A8080%2Fservlets-examples%2Fservlet%2FSessionExample

Content-Length: 0

Date: Fri, 28 Oct 2005 06:33:54 GMT

Server: Apache-Coyote/1.1

?

緊接著，我的 IE 訪問 casserver:7002 ，走 SSL 協議

__Q_M_Ca?R??d‰.!#U?-é?11úhx_??{?e???ò?_h|íA?6

?|__“w?o___

db____c_

?

casserver:7002 出示證書給我看，并且給予我 ServiecTicket, 下面的是亂碼， SSL 協議是這樣，將就一下 J

認證完畢，我得到ServiceTicket，我便用 casserver:7002 提供的 ServiceTicket 訪問 appserver01:8080 的 SessionExample應用

GET /servlets-examples/servlet/SessionExample?ticket=ST-1-9xVu1SfonRNKcjdyKbG9 HTTP/1.1

Accept: */*

Accept-Language: zh-cn,en;q=0.8,zh;q=0.5,zh-tw;q=0.3

appserver01:8080 認為我的 Ticket 是正確的，因此正確返回網頁給我。

HTTP/1.1 200 OK

IE會接著 獲取網頁上的圖片，見 GET 后面那一串字符，什么 code.gif,return.gif..... ，獲取的根據都是

靠那個 ticket=ST-1-9xVu1SfonRNKcjdyKbG9 ，如果這個 ST 不對，圖片是獲取不了的！
