After the page refresh or click on a hyperlink, the session before the stored value all lost, I think may be opened a new session window then sessionId to refresh, but I used to previous sessionId to get the session is empty,
Then I looked at someone sent a piece of code so

 & lt; script> 
The session. Use_trans_sid=1; 
The session. Use_only_cookies=0; 
</script> 

I put this code in the jump in front of the page after the values can be passed, but I can only transfer part of the backend Java code below

 
Request. GetSession (). The setAttribute (CDUTConstants USER_SESSION, user); 
//the current contact 
Request. GetSession (). The setAttribute (" phone ", username); 

Of the two assignment in another page for less than the former, but the latter can access to the new page, don't know why

As with js code it doesn't matter
