How to change Keep Alive time out in Internet Explorer 11

Internet Explorer uses Connection Keep Alive time out headers to establish a persistent HTTP connection with a Web server, and reuses the same TCP/IP socket that was used to receive the initial request for a period of up to 1 minute by default. If the socket remains idle for 1 minute, IE resets the connection.

If you wish, you can change this HTTP KeepAliveTimeout value in Internet Explorer 11, to say 2 minutes. This can be useful if the Web Server has a 2 minute time out value.

But if the Web Server has a 1 minute timeout, then changing this value will not make a difference, as the lower of the two values – Browser timeout and Server timeout, is always considered.

Create system restore point first and then Run regedit to open the Registry Editor. Now navigate to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings

Right-click on InternetSettings > New > DWORD.

Name the new DWORD in the right pane as KeepAliveTimeout, and give it a value 120000 in Decimal.

Exit the Registry Editor and restart Internet Explorer.

The 120000 value is 2 minutes in milliseconds.

To restore the value back to its default, delete KeepAliveTimeout or change its value to 60000.

If you wish to keep a time out or 3 minutes you will have to do the following – Give KeepAliveTimeout a value of 180000 AND create and give DWORD ServerInfoTimeout a value of 180000.
