Here are the different log levels provided by NLog, listed in increasing order of severity: Trace : The most detailed log level, used for tracing the execution flow. It provides very fine-grained information useful for debugging. Debug : Used for debugging and development purposes.

Working with Custom Claim Values in ASP.NET Core Razor Views: Accessing and Utilizing User-Specific Custom Claims in CSHTML Pages

  To access custom claim values in a Razor view ( .cshtml ) page in ASP.NET Core, you can use the User property and the FindFirstValue method to retrieve the specific custom claim value.

Here's an example: @using System.Security.Claims @{ var customClaimValue = User.FindFirstValue( "CustomClaimType" ); } <p>Custom Claim Value: @customClaimValue</p> In the above code, User.FindFirstValue("CustomClaimType") retrieves the value of the custom claim with the specified claim type, "CustomClaimType".

Controlling User Navigation: Strategies to Manage the Browser's Back Button in ASP.NET

In ASP.NET, you cannot directly disable the browser's back button as it is a functionality controlled by the user's browser. However, you can implement certain techniques to prevent users from navigating back to a specific page or performing certain actions. Here are a few approaches you can consider: Redirect on Page Load: On the page where you want to disable the back button, you can check if the user has navigated back using the browser's history. If so, you can redirect them to a different page or show an error message. You can achieve this by checking the Request.UrlReferrer property on the server side in the page load event. protected void Page_Load ( object sender, EventArgs e ) { if (!IsPostBack) { if (Request.UrlReferrer != null && Request.UrlReferrer.AbsolutePath.Contains( "PageToDisableBackButton.aspx" )) { // User has navigated back from the page you want to disable // Redirect them or sh

"Boosting ASP.NET Performance with Server-Side Caching: A Step-by-Step Guide

  Here's an example of how you can implement server-side caching in ASP.NET to improve performance: public ActionResult Index () { // Try to get the data from cache var cachedData = HttpContext.Cache[ "CachedData" ] as List<MyData>; if (cachedData == null ) { // Data is not in cache, so fetch it from the database or another source cachedData = GetDataFromDatabase(); // Store the data in cache with a sliding expiration of 5 minutes HttpContext.Cache.Insert( "CachedData" , cachedData, null , DateTime.Now.AddMinutes( 5 ), TimeSpan.Zero); } return View(cachedData); } In this example, we're using the HttpContext.Cache object to store and retrieve data from the server-side cache. Here's what the code does: First, it tries to retrieve the data from the cache using the key "CachedData". If the data is found in the cache ( cachedData != null ), it is used directly. If the data is
