    copied!<p>I develop asp.net web forms application in VS2012 a I have one project with Web.App and one project is a Class Library. In a class library i reading configuration from web.config (in a project is a lot of app settings like path for menu file, log file etc...) and in this assembly i have a class for caching and logging events to file.</p> <p>This is a part of cache class:</p> <pre><code>public static class MyCache { public const String CACHE_MENU_USER = "CACHE_MENU_USER_{0}"; public const String CACHE_LOG_FILE_PATH = "LOG_FILE_PATH"; public static void AddToCache(String cacheKey, Object value, DateTime absoluteExpiration, bool loggToFile = true) { HttpContext.Current.Cache.Add(cacheKey, value, null, absoluteExpiration, Cache.NoSlidingExpiration, CacheItemPriority.High, (k, v, r) =&gt; //key, value, reason of remove from cache { String reasonOfRemove = String.Empty; switch (r) { case CacheItemRemovedReason.DependencyChanged: reasonOfRemove = String.Format("CacheItemRemovedReason.DependencyChanged"); break; case CacheItemRemovedReason.Expired: reasonOfRemove = String.Format("CacheItemRemovedReason.Expired"); break; case CacheItemRemovedReason.Removed: reasonOfRemove = String.Format("CacheItemRemovedReason.Removed"); break; case CacheItemRemovedReason.Underused: reasonOfRemove = String.Format("CacheItemRemovedReason.Underused"); break; } AppConfiguration.Logger.WriteMessage(String.Format("Key {0} was removed for reason: {1}", cacheKey, reasonOfRemove)); }); if (loggToFile) AppConfiguration.Logger.WriteMessage(String.Format("Insert cache key {0} from now to: {1}", cacheKey, absoluteExpiration)); } } </code></pre> <p>AppConfiguration is a static class with static properties with values from web.config. Logger is a instance of Logger class.</p> <p>In global.asax is a piece of code:</p> <pre><code>protected void Application_Start(object sender, EventArgs e) { AppConfiguration.ReadConfiguration(); AppConfiguration.Logger.WriteMessage("Start app"); } protected void Application_End(object sender, EventArgs e) { AppConfiguration.Logger.WriteMessage("End app"); } </code></pre> <p>Problem is, that App_Start is called on every request a inserted value to cache is immediately removed...</p> <p>this is a part of log file:</p> <p>10.8.2013 17:14:22: Start app.</p> <p>10.8.2013 17:14:23: Insert cache key CACHE_MENU_USER_DEMO\Administrator from now to: 8/17/2013 5:14:23 PM</p> <p>10.8.2013 17:14:23: Key CACHE_MENU_USER_DEMO\Administrator was removed for reason: CacheItemRemovedReason.Removed</p> <p>10.8.2013 17:14:23: End app.</p> <p>a this is repeated with every request. </p> <p>I was trying start application in IIS Express, i trying start application in server (IIS7, Windows server 2008 R2) and it is still the same...</p> <p>Any idea what is wrong with cache and global.asax? Thanks</p> <p><strong>EDIT:</strong> *<em>Problem solved. More is in comments from FlopScientist</em>*</p>
