[big][b]Internet Explorer error "connection timed out" when server does not respond[/b][/big] SYMPTOMS [i]When you connect to a Web site that runs for a while before it returns information to Internet Explorer, you may receive one of the following error messages.[/i] Message 1 Microsoft Internet Explorer error 10060 connection timed out. Message 2 Internet Explorer cannot open the Internet site .The operation timed out. Message 3 The page cannot be displayed.Cannot find server or DNS Error. CAUSE [i]Internet Explorer imposes a time-out limit for the server to return data. By default, the time-out limit is as follows: Internet Explorer 4.0 and Internet Explorer 4.01 5 minutes Internet Explorer 5.x and Internet Explorer 6.x 60 minutes Internet Explorer 7 and Internet Explorer 8 60 minutes Internet Explorer does not wait endlessly for the server to come back with data when the server has a problem.[/i] RESOLUTION [i]If a page does not return within a few minutes, many users perceive that a problem has occurred and stop the process.Therefore, design your server processes to return data within 5 minutes so that users do not have to wait for a long time. You can usually break down long processes into smaller pieces. Or, the server can return status data to update users about the process. In addition, you can create a long server process with a messages-based or asynchronous approach so that it returns immediately to the client after the job is submitted and notifies users when the long process is finished[/i]
