session-variables

I would like to know whether is it possile to retrieve the session object and access its attributes from a Thymeleaf template without any controller code. Rafal Borowiec In Thymeleaf, session object can be easily accessed in a template: with a session variable: ${session.foo} // Retrieves the session atttribute 'foo' ${session.size()} ${session.isEmpty()} ${session.containsKey('foo')} with a #ctx object: ${#ctx.httpSession} Look at the Thymeleaf documentation for accessing different context objects: http://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html#expression-basic-objects 来源：

What is the difference between these 2 piece of codes. HttpContext.Current.Session["myvariable"] Session["myvariable"] asp.net 4.0 and C# 4.0 They're effectively the same, in that they will access the same Session data. The reason you can call Session in your code-behind is because ASP.Net pages by default extend the System.Web.UI.Page type. This has a Session public property. If you look at the code for this in Reflector you can see that it just calls HttpContext.Current.Session itself (through its own Context property). In other classes you will not have access to that property, but you can

.NET's HttpSessionState using an " InProc " store seems to treat session variable key values as case insensitive. For example: session["foo"] = 1; session["Foo"] = 2; Trace.Write(session["foo"].ToString()); // => 2 This behavior appears to be undocumented, so I'm wondering if it is simply a side-effect of the underlying session store mechanism, or intentionally implemented by the class itself. Since C# treats everything else as case-sensitive, it is a bit unnerving for the session to not act the same way. What gives? Does it differ by store type? Is it there for backwards-compatibility with VB

In my web app I'm using some session variables, which are set when I login: e.g. Session("user_id") = reader("user_id") I use this through my app. When the session variable times out, this throws errors mainly when connecting to the database as session("user_id") is required for some queries. How can I set my session variables so that once they are timed out to go to the login page or how can at least increase the length of time the are available? Kev I'm guessing you're using Forms Authentication. The trick here is to ensure that your Forms Authentication expires before the session does. I

I am getting name and email id of a user after he logs in via facebook to my website.. I want to add those variables in session on login form itself using javascript; I tried following: FB.api('/me', function(me) { if (me.name) { document.getElementById('auth-displayname').innerHTML = me.name; <% Session["fbName"] = me.name; %> } } it gives error like me (in this line: <%Session["fbName"] = me.name; %>) does not exist in the current context etc.. my div "auth-displayname" is getting that value but I'm having problem with session variable How can I do this You can use sessionStorage.SessionName

I've only seen examples of session variables being used to store small amounts of data, like a single user id. I'm wondering if it would be more efficient to instead hold more frequently accessed data in the session variables to avoid querying the database. For instance, I made a user class that gathers regularly requested data for that user upon construction (their user id, username, email, password and arrays of site specific data) and I hold this instance as a session variable. After the user's initial log in, the database rarely has to be queried to get information about the user because

I'd like to construct an object in different steps in an asp.net mvc application, each step being a different page. The sort of thing you'd store in Session in a quick Web.Forms application. Reading about it, Session doesn't seem to me as something very asp.net MVC'ish. However I can't really think of other alternatives to this situation as TempData and ViewData don't seem to fit either, so maybe I'm wrong. Of course I could put the 4 steps in one page and show/hide, but that's not my point with the question. I'd like to hear your opinion about Session in MVC, if it's a good aproach for this

Can someone point out what the new Rails 3.x session configuration options are? I'm trying to duplicate the same configuration that I have in my Rails 2.3.x application. This is the configuration that I used in the application: #environment.rb config.action_controller.session_store = :active_record_store config.action_controller.session = { :key => '_something', #non-secure for development :secret => 'really long random string' } # production.rb - override environment.rb for production config.action_controller.session = { :key => '_something_secure', :secret => 'really long random string',
