I just finished taking a final exam on web applications. Capping off what had been a rather easy (albeit lengthy - 12 pages) exam was a question asking us to code an implementation of sessions, similar to that done by javax.http.HttpSession. I hate to admit, it stumped me. I cranked out a rather BS implemetation using a HashMap and did...
I'm a designer who dabbles in scripting using JQuery and PHP. I have a pretty good understanding of functionality in both but using sessions is new to me. I have an app with a search feature. The search results may stretch over several pages and each result has a checkbox. The idea is the user goes through the results and checks off ite...
is it possible to create session variables with jquery or javascript or do i have to use ajax to call a php that does that? ...
I have webRole with some data stored in Session. The data is some tens of small variables (strings), and one-two big objects (some megabytes). I need to run this webRole in multiple instances. Since two requests from the single user can go to different instances, Session became useless. So, i am looking for most efficient and simplest me...
if an administrator logs on to my service, he may wish to disconnect sessions which meet (or don't meet) certain requirements, be it automated or manual. throwing exceptions seems like a simple and effective solution, as all resources are released. i could use a local bool field which, if true, would disconnect this user the next time h...

Commonly, a website has a menu bar with links to different pages of the site— Home, Page A, Page B, etc.. Let’s say you have a site with address http://www.example.com. 99% when someone types that URL into their browser, they are directed to the page represented by “Home”. It usually has the optional extension of index[.html|.php] (e.g....
It took me a while to realize that $_SESSION['user'] was changing because I have a variable set: $user = array(); Is this normal? I haven't had this issue until today, not sure if it is a server/php setting ...
I've used Coldfusion sessions for quite a while, so I know how they are used, but now I need to know how they work, so that I can plan for scaling my website. Is a Coldfusion user 'session' simply a quick method to setup 2 cookies (CFTOKEN and CFID) and an associated server side memory structure? (the SESSION scope) Does it do anything ...
The first line of code, called on every one of my application's pages, is: <?php require_once('../../_includes/initialize.php'); ?> That file calls my classes, including SESSION. The SESSION class calls session_start() before anything is output to the browser. On one page I'm using a form that has a ton of checkboxes, all with the na...
I know a few sits (such as my bank and my school) that kill a session after their has been idle for a set amount of time. It is my understanding that session activity is determined by users following links or at the very least from some kind of active interaction, like updating a form via ajax. Basically the server gets a request to do s...
I've (so far) been handling user sessions with client-side cookies and database entries. When the user logs in, I generate a guid and place it in a cookie on the client's computer. Then I create an entry in a 'sessions' MySQL table, and add there the guid, ip address, the username, privileges, etc. Then when the user accesses the page, ...
Hello all, I'm getting a Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent error even though the first line of my file looks like: <?php session_start(); all the answers I saw on other sites said it was from sending info to the server before starting the session.

Cookie: ASP.NET_SessionId=gf0ouay24sdneiuicpiggn45; However, when I'm running the soap test hitting my local server it doesn't have an ASP.NET_Session variable in the cookie. Why is this happening? UPDATE:...

In our application, we have a "BasePage" that declares a number of properties to be used by more or less every page in the app. Inside these properties, they write to ViewState. These are all typically an int or small string value, nothing huge. Typical use is call a web service and hold an id for use within the page, for example. I'v...
