Sitecore cache clear

Sometime you just need to clear the caches on a sitecore server. Use the script below to save having the sitecore folder on your front end web server.

 <script language="CS" runat="server">  
  protected override void OnLoad(EventArgs e)  
  {  
  if (Request.QueryString["ClearCache"] != null)  
  {  
   Sitecore.Context.Database = this.WebContext.Database;  
   Sitecore.Context.Database.Engines.TemplateEngine.Reset();  
   Sitecore.Context.ClientData.RemoveAll();  
   Sitecore.Caching.CacheManager.ClearAllCaches();  
   Sitecore.Context.Database = this.ShellContext.Database;  
   Sitecore.Context.Database.Engines.TemplateEngine.Reset();  
   Sitecore.Caching.CacheManager.ClearAllCaches();  
   Sitecore.Context.ClientData.RemoveAll();  
   InfoLiteral.Text = "All sitecore cache has been cleared. DateTime:" + DateTime.Now.ToString();  
  }  
  else  
  {  
   InfoLiteral.Text = "You haven't entered correct query parameter. DateTime:" + DateTime.Now.ToString();  
  }  
  base.OnLoad(e);  
  }  
  private Sitecore.Sites.SiteContext WebContext  
  {  
  get  
  {  
   return Sitecore.Configuration.Factory.GetSite(Sitecore.Configuration.Settings.GetSetting("stagingSiteContext", "website"));  
  }  
  }  
  private Sitecore.Sites.SiteContext ShellContext  
  {  
  get  
  {  
   return Sitecore.Configuration.Factory.GetSite("shell");  
  }  
  }  
 </script>  

Enjoy!
