Asp net session crashing only on 1 clients ie 11

ASP.NET is a widely used programming language for developing web applications. It provides a powerful framework for building dynamic and interactive websites. However, like any other programming language, ASP.NET can sometimes encounter issues that need to be resolved. One such problem is the crashing of ASP.NET sessions on specific clients, particularly Internet Explorer 11 (IE 11).

When a user visits a website built with ASP.NET, a session is created to maintain state and store user-specific data. This session allows the website to remember user preferences, track their activities, and provide a personalized experience. However, in some cases, the ASP.NET session may crash only on certain clients, such as IE 11.

To understand why this issue occurs and how to solve it, let's delve into the possible causes and solutions.

Possible Causes

can be reasons why ASP.NET sessions crash only on specific clients like IE 11. Some of the common causes include:

1. Browser Compatibility: Internet Explorer 11 may have compatibility issues with certain ASP.NET features or configurations, leading to session crashes.

2. Outdated Browser: If the is using an outdated version of IE 11, it may lack necessary and patches, compatibility problems with ASP.NET sessions.

3. Security : The security settings of IE 11 can sometimes interfere with the functioning of ASP.NET sessions, resulting in crashes.


To resolve the issue of ASP.NET session crashing on specific clients like IE 11, you can try the following solutions:

1. Update Internet Explorer: Ensure that the client's IE 11 browser is up to date. Microsoft regularly releases updates and patches to address compatibility issues. Updating the browser may resolve the problem.

2. Clear Browser Cache: Ask the client to clear their browser cache and cookies. Sometimes, outdated or corrupted cache files can interfere with the functioning of ASP.NET sessions. Clearing the cache can help eliminate such issues.

3. Check Compatibility Mode: Internet Explorer has a compatibility mode that emulates older versions of the browser. If the client has enabled compatibility mode for the website, it may conflicts with ASP.NET sessions. Ask the client to disable compatibility mode for the website.

4. Verify ASP.NET Configuration: Ensure that the ASP.NET configuration is correctly set up on the server-side. Check if the session state mode is properly configured and that the necessary session timeout values are set. Incorrect configuration can lead to session crashes.

5. Test with Different : Ask the client to test the website on different browsers like Google Chrome, Mozilla Firefox, or Microsoft Edge. If the session works fine on other browsers but crashes only on IE 11, it indicates a browser-specific issue.


Let's consider an example of ASP.NET code that demonstrates the usage of sessions:

// ASP.NET code to store and retrieve data from session
protected void Page_Load(object sender, EventArgs e)
    if (!IsPostBack)
        // Storing data in session
        Session["Username"] = "JohnDoe";

protected void btnRetrieve_Click(object sender, EventArgs e)
    // Retrieving data from session
    string username = Session["Username"].ToString();
    lblUsername.Text = "Welcome, " + username;

In this example, the code stores the username “JohnDoe” in the session during the Page_Load . When the user clicks the “Retrieve” , the code retrieves the stored username from the session and displays it on the webpage.

Remember to include the necessary ASP.NET session configuration in the web.config file to ensure proper session management.

By following the solutions mentioned above and ensuring proper configuration, you can resolve the issue of ASP.NET session crashing on specific clients like IE 11. It is essential to test the website thoroughly on different browsers to ensure cross-browser compatibility and a seamless user experience.
