public class class1 {      private const string dummycacheitemkey = "gagagugugigi";      protected void application_start(object sender, eventargs e) {         var result = registercacheentry();         if (!result) {             debug.writeline("the dummycacheitem alive!");         }     }      public bool registercacheentry() {         if (null != httpcontext.current.cache[dummycacheitemkey])             return false;         try {             httpcontext.current.cache.add(dummycacheitemkey, "test", null, datetime.maxvalue, timespan.fromminutes(1), cacheitempriority.normal, new cacheitemremovedcallback(cacheitemremovedcallback));          }catch( exception ex) {             debug.writeline("exeption error: " + ex);         }         return true;     }      public void cacheitemremovedcallback(string key, object value, cacheitemremovedreason reason) {         debug.writeline("cache item callback: " + datetime.now.tostring() + " removed!");          try {             hitpage();         }catch(exception ex) {             debug.writeline("hitpage unsuccessful: " + ex);         }          // service works           dowork();         //sendmail();      }      private const string dummypageurl = "http://localhost:53509/page.cshtml";      private void hitpage() {         webclient client = new webclient();         client.downloaddata(dummypageurl);     }       protected void application_beginrequest(object sender, eventargs e) {         // if dummy page hit, means want add item          // in cache          if (httpcontext.current.request.url.tostring() == dummypageurl) {             // add item in cache , when succesful, work.              registercacheentry();         }     }      private void dowork() {         debug.writeline("begin dowork...");         debug.writeline("running as: " +               windowsidentity.getcurrent().name);          dosomefilewritingstuff();          debug.writeline("end dowork...");     }       private void dosomefilewritingstuff() {         debug.writeline("writing file...");          try {             using (streamwriter writer =              new streamwriter(@"c:\temp\cachecallback.txt", true)) {                 writer.writeline("cache callback: {0}", datetime.now);                 writer.close();             }         } catch (exception x) {             debug.writeline("error: " + x);         }          debug.writeline("file write successful");     } } 

and here explanation of why did this?

is there simpler way it?

use "task scheduler" run programme in specific time.

find typing "task scheduler" in start menu.
