Tips for Session Timeouts In .NET

Session timeouts are an important security feature for web applications, as they can help protect against session hijacking and other types of attacks. When implementing session timeouts in a .NET application there are a few best practices to keep in mind:

  1. Use a reasonable timeout value: The session timeout value should be set to a reasonable value that balances security concerns with user experience. A value of 20-30 minutes is often a good starting point, but you should adjust this based on your specific application and user needs.
  2. Notify the user before the session expires: It’s a good idea to give users a warning before their session is about to expire. This can be done by displaying a message on the page, or by using a pop-up or another notification method. This can help prevent users from losing their work if they are actively using the page when their session times out.
  3. Handle session timeouts gracefully: When a user’s session expires, you should handle it gracefully by redirecting them to a login page or other appropriate location. This should be done in a way that does not cause any errors or unexpected behavior for the user.
  4. Consider using a sliding expiration: A sliding expiration is a session timeout that is extended each time the user interacts with the application. This can help ensure that users do not lose their work due to inactivity, while still providing a reasonable level of security.
  5. Use HTTPS: When transmitting sensitive information, such as session tokens, it’s important to use HTTPS to encrypt the data and prevent it from being intercepted by attackers.

Overall, session timeouts are an important security feature for any web application and should be implemented carefully to ensure that they provide the necessary protection without unduly inconveniencing users. By following these best practices, you can help ensure that your .NET application provides a secure and user-friendly experience for all of its users.

Compare Two Files in Visual Studio

Today I had some files that I needed to compare. For years to compare two files in Windows I have relied upon WinMerge. But, I realized I had not used WinMerge in quite a long time and had not even installed it on my new box. Most of the time I just use SourceTree, as we are GIT shop, to do diffs now. To see version history of a single files different versions this works great.  (I realize there are MANY ways to do diffs.)

In this case though I needed to see the difference between the same file in two places in my project. Knowing that Visual Studio could handle this well but not remembering how to do it, I of course googled.

You can access Visual Studio’s built in diff tool via commandline in Windows or via the command window in VS. I choose the command window in VS.

Go to: View — Other Windows — CommandWindow

Then in the command window I ran the following command: 

It worked like a champ and shows me the diff without an extra install.

I found this information here.
