Caching HTML with Cache TagHelpers

In this recipe, we will learn how to use Cache TagHelpers.

Getting ready

TagHelpers let developers use their C# classes and methods in CSHTML files. With TagHelpers, developers can reuse most of the C# codes and logics in CSHTML files.

We will now create a view where we will use Cache TagHelper to cache elements in a view.

How to do it...

1. First, we use the TagHelper expires-after:

<!-- expires-after -->  
<cache expires-after="@TimeSpan.FromMinutes(10)">
    @Html.Partial("_MyPartialView")
</cache>

2. Next, we use the TagHelper expires-on:

      <!-- expires-on -->  
      <cache expires-on="@DateTime.Today.AddDays(1).AddTicks(-1)">
         @Html.Partial("_MyPartialView")
      </cache>

3. Next, we use the TagHelper expires-sliding:

      <!-- expires-sliding -->  
      <cache expires-sliding="@TimeSpan.FromMinutes(5)">
         @Html.Partial("_MyPartialView")
      </cache>

4. Next, we use the TagHelper vary-by-user...
