Class HttpContextRequestAppCache

Implements a on top of Microsoft.AspNetCore.Http.IHttpContextAccessor

Inheritance
System.Object
Namespace: Umbraco.Cms.Core.Cache
Assembly: Umbraco.Web.Common.dll
Syntax
public class HttpContextRequestAppCache : FastDictionaryAppCacheBase
Remarks

The HttpContext is not thread safe and no part of it is which means we need to include our own thread safety mechanisms. This relies on notifications: and in order to facilitate the correct locking and releasing allocations.
