session-variables

I have a jetty container with two different servlets, lets call then A and B. In a special occasion a qr code code appear in servlet A (the user is already logged in and is using his desktop) and the user by using his mobile device read this qr code and is redirected the servlet B on his mobile device. The problem here is that i cant keep his session. The QR code brings the user session key however i have no way to verify if this session is valid. I would like to know if there is any special method to request the valid session keys on jetty, since both servlet are in the same server. Well the

I'm trying to send the value of this php get_field variable from a wordpress Archive page. get_field('supplier_email_address', 'product_brand_' . $term->term_id ); to another sendmessage.php page which is never accessed other than with the of JS to send a form. The variable I need filled is called: $sendto="value"; How can I achieve this? EDIT: Apparently this requires more information. Use session variables. First of all every page you want to use sessions on needs to have the function session_start(); declared at the top of every page. You then can use the session superglobal to store things

I will be populating DataTable and other controls from a complex object . Where should I store such an object ? At what size does session variables starts affecting the performance of page? Data in the Session object is stored in memory on the server. Thus the storage limit is the memory available to the server. This data is not sent to the client at any stage, unless you explicitly do so. Instead the MVC code sends a cookie to the client browser once you have assigned any value to the Session object. The value of this cookie is then used to uniquely identify the session. So... The Session

I am just learning grails and have a problem with an app that works fine when I run it in Netbeans but shows strange behavior when deployed to Tomcat 7.0.22 on a Centos 5.4 server. I am using the proxy_ajp to make the app available with apache. The problem seems to be with the session not being maintained after a redirect so that I lose the login information causing the app to try to login again. My proxy_ajp settings are <Location /PreyerBooks > ProxyPass ajp://localhost:8011/PreyerBooks ProxyPassReverse ajp://localhost:8011/PreyerBooks </Location> the app is deploying without errors and the

I am developing a simple php/mysql discussion forum. The statement <?php print $_SESSION['username']; ?> produces the desired results on my local machine, but when I uploaded the code to test the forum live, the value of the session variable no longer displayed. What could be causing this? one thing that can cause this is if the live web server is on a load balanced environment using default php session handling. By default php stores session data in a flat file on ther server so if the user is jumping around webheads they will lose session data. in that case you will need to define your own

I can't find the solution to this one. Basically we are using a vanity url system so its user.domain.com. All files are accessed like user.domain.com/home.php etc. When you clear cookies the redirects work, it prompts them to login again. But when i use logout, it still works but when they go back to the link to login, (user.domain.com, has a login form on the landing page for the user) it won't work. The error i get is Error Message: The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This

In MySQL, I can create an access a session variable by using a single @. Example initialization: set @myVar = true; Some trigger containing this code: if (@myVar is not true) then execute something What is the equivalent in Oracle 10g? SQL> EXEC DBMS_SESSION.SET_CONTEXT('CLIENTCONTEXT', 'myvar', 'myvalue'); PL/SQL procedure successfully completed SQL> SELECT SYS_CONTEXT('CLIENTCONTEXT', 'myvar') FROM dual; SYS_CONTEXT('CLIENTCONTEXT','M -------------------------------------------------------------------------------- myvalue Thomas Jones-Low A package global variable would probably do the same

In ASP an uninitialized Session variable Is Empty. I know that the correct way to check for a Session value, and remove a value, is the following: IF NOT IsEmpty(Session("myVar")) THEN ' Go ahead and use Session("myVar") ... ' Now if we're all done with myVar then remove it: Session.Contents.Remove("myVar") END IF I've inherited a codebase where Application and Session variables are typically set = "" after use, and all tests for a value are of the form (Sessions("myVar") = "") . This test appears to work when the Session variable has not been declared ... or maybe it's just working by dumb
