For some reason, I expected this to be a no-brainer when I first worked on an app that needed this functionality. Turns out there several complications that we need to be aware of. On top of that, be prepared for the potential of a lot of test points on a single page.
I like to set the browser session to a shorter time period than authentication, because I end up running into extra issues to code around if the authentication expires first and the session is still active. I got this idea from this article on StackOverflow.
Ajax call. We use it to check if the response returned an indication that a timeout occurred, before attempting to process.
It assumes that the parameter, datais passed in from the AJAX call response. The parameter, datashould be the response from an AJAX call attempt. Once that AJAX call is made, this function will call itself with an actual data value that can now be interrogated. The function returns true if no timeout occurred yet. We simply execute our callback logic if the result of this call is true no timeout occurred :.
Again, if you want to check for a timeout where no AJAX call is needed, such as for a click event when the user is navigating a list box, just call checkTimeout with no parameter. If you have any improvements on this, please post a comment. What do you use SessionExpireFilterAttribute for? Hi Shane. Name in the AccountController Logon post action, if the logon was successful.
If it determines a timeout has not occurred, it allows the actual called action to execute. Otherwise, it forces a redirect to a timeout notification page, which in turn redirects to the logon page to allow the user to re-logon.
Browser timeout? I want to set the timeout manually to 20 minutes and display the metatag message for 1minute with options to stay in or logout 2 buttons. Please help me.This topic describes several common mistakes people make within ASP.
NET web projects. It provides recommendations for what you should do to avoid these common mistakes. This topic is not intended as a complete guide to ensure your application is secure and efficient. You still need to follow best practices for security and performance that are not outlined in this topic. It only suggests how to avoid common mistakes related to. NET classes and processes. Controls Adapters were introduced in.
NET 2. Recommendation: Stop setting style values in the control markup, and instead set formatting values in CSS stylesheets.
Session In MVC 4 - Part 1
Web server controls contain dozens of properties which can be used to set in-line style properties. For example, the ForeColor property sets the color of the text for a control. You can accomplish this same effect more efficiently through CSS stylesheets.
Stylesheets enable you to centralize style values and avoid setting these values throughout your application. In earlier versions of ASP. NET, Page and Control callback methods enabled you to update part of the web page without refreshing an entire page. You should stop using callback methods because they can cause issues with friendly URLs and routing. By default, controls do not enable callback methods, but if you enabled this feature in a control, you should disable it.
Getting Started With Areas in MVC 5
Recommendation: Stop using static browser capability detection, and instead use dynamic feature detection. Detecting feature support through a static lookup is not the best approach. Now, you can dynamically detect a browser's supported features by using a feature detection framework, such as Modernizr. Feature detection determines support by attempting to use a method or property and then checking to see if the browser produced the desired result.
By default, Modernizr is included in the Web application templates. Request validation is a feature of ASP. NET that inspects each request and stops the request if a perceived threat is found. Do not depend on request validation for securing your application against cross-site scripting attacks. Instead, validate all input from users and encode the output. In some limited cases, you can use regular expressions to validate the input, but in more complicated cases you should validate user input by using.
NET classes that determine if the value matches allowed values. The following example shows how to use a static method in the Uri class to determine whether the Uri provided by a user is valid.
However, to sufficiently verify the Uri, you should also check to make sure it specifies http or https. The following example uses instance methods to verify that the Uri is valid. Before rendering user input as HTML or including user input in a SQL query, encode the values to ensure malicious code is not included. Passing authentication information in the query string is not secure.Why not use Server.
Transfer instead of Response. Redirect especially if both pages are aspx? Excellent question. Transfer will not get the right URL in the address line of the user's browser. Now, Transfer also has a Response. End and hence a ThreadAbortExceptionbut the code inside Transfer is really just two lines: Execute path, null, preserveForm ; Response. End ; So you see that to avoid the exception for Transfer, you should just use Execute instead.
Of course, if you do that, you still need to suppress the output from the first page because both pages will output to the same response you don't need to do that with Redirect because you have two separate requests in this case, and thus two different responses, the first one being thrown away. This can be done by clearing the response before calling Execute or doing some funny stuff with the writer parameter of Execute.how to set session timeout using inproc mode in asp net web config
Many strange scenarios here. I tried to used the Response. Tried Response. I still have the same issue. Redirect "default. I tried all 3 of the above in a small bit of test-code But my production code about lines does lose session vars I can't seem to "make" it happen with redirect Disappointed: drop me e-mail using the "e-mail" page of this blog with a simple repro avoid dependancies if you can, try to make it as simple as possible and I'll try to find what's wrong.
Carol: you will only lose session variables if the session does not yet exist when you do the redirect. What doesn't get set here is not the session variable in itself, it's the cookie that identifies the session.
How can I lose something Can you give an example in asp. I need code that I can run Not the current "randomly" methodIf you look at any discussion forum related to Session, you will come across the issue of Session.
Timeout not working properly. I faced the same issue when I initially implemented session in my project. Session can be set in the web.
Timeout parameter which is provided by Microsoft. Before going into a detail discussion of why Session. Timeout does not work, first we need to look at the architecture of IIS. Then we can easily understand when Session. Timeout fails or when it works. If you look at the above architecture of IIS, we have different application pools available.
If we want, we can create new application pools. We also have a default application pool. For each and every application pool, a worker process will be created as a result of which each and every application pool can run independently.
Moreover, each and every application pool will have its own session timeout value. This means that when the session timeout value is reached, the application pool will be restarted.
And whenever we create a web site that will fall under any one of the application pools, if we don't specify anything, then they will fall under the default application pool. The website shown below has its own session timeout value:. If we look at the above figure, we can see the session timeout parameter. This is at the web site level, and Microsoft had provided a parameter for controlling this: Session.
Using this, we can change the session timeout value from the code-behind file. The crux of this is, we have two things: the application pool that has its own session timeout value, and the web site that also has its session timeout value.
Microsoft has given the parameter Session. Timeout to change the website session timeout value. We have to understand one thing here: we have to make sure that the application pool session timeout value is always greater than the website session timeout value; only the will the Session. Timeout parameter work; otherwise, it won't.
The reason is as follows: whenever the application session timeout is reached, the application pool will be restarted and because of that Session. Timeout of the website parameter won't work. Website Session. Timeout will work only when it is less than the application pool session timeout value; because whenever the application pool session timeout value is reached, that particular application pool will be restarted.This article provides a basic introduction to creating and working with areas in MVC 5 with Visual Studio You all know that MVC Model, View, Controller is a design pattern to separate the data logic from the business and presentation logic.
We can also design the structure physically, where we can keap the logic in the controllers and views to exemplify the relationships. It is also possible that we can have large projects that use MVC, then we need to split the application into smaller units called areas that isolate the larger MVC application into smaller functional groupings. In this article I am creating a simple application for defining the area in MVC 5.
Use the following procedure to create a Web application based on a MVC 5 template. Step 2: Create an ASP. Step 3: In Solution Explorer, right-click on the project and click "Add" to add an area as shown below:. Step 4: Enter the name for the area, such as "News". Step 5: Similarly add an another area named "Article".
Now from the steps above you have added two areas for your application named News and Article. We have successfully added an area, now we'll add controllers for each of our areas using the following procedure. Step 1: Right-click on the Controller in your Article area to add a controller. Step 3: Enter the name as "ArticleController". Now your Area folder should be as in the following screenshot:. We have successfully added a controller for our area, now to add a view for the area using the following procedure.
Step 2: Enter the view name as defined in the NewsController. Step 3: Generate some content in the View of News as in the following screenshot:. Step 4: You can also add a view as shown in the following screenshot:.
RegisterAllAreas. Application Execution. Step 1: Open the project view Layout file. Step 3: Debug the application and open the Article link as shown below:. Step 4: Similarly open the News link:. You can also create controllers, models and views depending upon the situation.I can log on fine, but if I click the Log Off link, I don't get logged off.
My user name is still shown in the top right of the page, and the Log Out link is still there. I've spent a long time searching, and tried a lot of things, but haven't found anything that works yet. SignOut method should invalidate your authentication token and force you to re-authenticate.
Have you tried placing a breakpoint within your LogOut Controller Action to ensure that it is being hit? Post so I suppose that you could try simply decorating your LogOut method with an [HttpPost] attribute as seen below to see if that makes any difference :.
The odd thing is that I just tried it again, and it's working fine!
I don't know if my machine just needed a reboot, or something else was going on, but I haven't changed the code. SignOut not working in MVC5?

I set the variables in the global. Later in the application I try to call the session variable and it is always null. After doing some research I found that using session variables in MVC is different than in regular.
Can someone help explain to me how to use session variables in MVC? Are there references you have to include? Anything in the web. I am at a loss MVC Session Variables. Sorry, is that in the HomeController page?
Session Handling in ASP.NET MVC 5 for Synchronous/Asynchronous Requests
If so, do i have to import a namespace or how do i reference my home controller in the ViewUserControl page? Nov 15, AM crocboy25 LINK It works locally on my PC but when the code gets moved to the development server, it doesnt pick up the session variable in the controller. It is like it drops the session once it leaves the global. Very frusterating.
I haved checked the IIS setting on the development server and I dont see anything that jumps out at me that would mess it up. I think it is not the problem of your code but the server. It is hard to find out the cause since we are hard to reproduce the issue on our side. And also check if the code in the Global.
If yes, then you would have to use sticky sessions. Print Share Twitter Facebook Email. Vijay Kodali My Blog "Don't be afraid to be wrong; otherwise you'll never be right.
