    <p>Below is the two ways I know how tomcat keep session as so far. </p> <ol> <li>In URL add parameter like "JSESSIONID=xxxxxxxxxxxxxxx", every time when a request send to server side, tomcat will query the session-map with "xxxxx" </li> <li>Add a field in cookie like "JSESSIONID=xxxxxxxxxxxxxxx". </li> </ol> <p>So, in my understanding, if we disable Cookie in browser, and visit our page with a URL without parameter like "JSESSIONID=xxxxxxxxxxxxxxx". The session id will be changed. Write a piece of code in jsp </p> <pre><code>&lt;% out.println(request.getSession().getId()); %&gt; </code></pre> <p>whenever we visit this jsp, session id will change. But the fact is that sessionId is never changed. </p> <p>I observed the cookies in browser, <strong>I have indeed disabled cookie</strong>. When the first time I visit the page, the request and resonse like below: </p> <pre><code> Request URL:http://localhost:8080/examples/testt.jsp Request Method:GET Status Code:200 OK ---------- Request Headersview source Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:zh-CN,zh;q=0.8 Cache-Control:max-age=0 Connection:keep-alive Host:localhost:8080 User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.162 Safari/535.19 ------- Response Headersview source Content-Length:342 Content-Type:text/html;charset=ISO-8859-1 Date:Sat, 05 May 2012 03:01:32 GMT Server:Apache-Coyote/1.1 Set-Cookie:JSESSIONID=6C71760FD3B85C4696CD8E6204574A06; Path=/examples </code></pre> <p>When the second time I visit the page, the request and resonse like below: </p> <pre><code>Request URL:http://localhost:8080/examples/testt.jsp Request Method:GET Status Code:200 OK -------- Request Headersview source Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:zh-CN,zh;q=0.8 Cache-Control:max-age=0 Connection:keep-alive Cookie:JSESSIONID=6C71760FD3B85C4696CD8E6204574A06 Host:localhost:8080 User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.162 Safari/535.19 -------- Response Headersview source Content-Length:342 Content-Type:text/html;charset=ISO-8859-1 Date:Sat, 05 May 2012 03:03:19 GMT Server:Apache-Coyote/1.1 </code></pre> <hr> <p>Could someone tell me how tomcat keep a session when cookie is disable and URL doesn't contains "JSESSIONID=xxxxxxxxxxxxxxx". </p> <p>Thanks very much.</p> <hr> <p>I have made a mistake when I disable cookie in Chrome, I haven't really disable cookie in the above test. </p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
