This software enables users to control Internet Explorer's caching of DNS records, server connection timeout, and server information by adjusting hidden registry settings.
This software tool offers the ability to adjust three hard to find registry settings in Internet Explorer, providing the user with the ability to control the caching of DNS records, server connection timeouts, and caching of server information. This is particularly useful when testing web servers with constantly changing DNS records or IP addresses, such as those utilized in DNS Round Robin or Simple Failover setups.
However, Internet Explorer is known to not honor or use the TTL value provided in DNS records. Instead, it caches all DNS records for a fixed amount of time, as determined by the setting in this tool. It's important to note, though, that there is one exception: after Internet Explorer has fetched a web-page, it keeps the TCP connection open rather than immediately closing it, which allows for faster execution of following requests to the server.
This setting has an impact on both DNS caching and server connections in terms of "keep alive" timeouts. Specifically, Internet Explorer will not refresh DNS records if another page is requested from the same server domain name within this time interval, even if the DNS Cache Timeout setting has a lower value. Basically, DNS records time out based upon the higher value of DNS Cache Timeout and this setting, while server connections appear to time out based upon the lower value of Keep Alive Timeout and this setting.
For the most predictable results when using this software tool, the value of this setting should be set either lower than or equal to the DNS Cache Timeout setting or higher than or equal to the Keep Alive Timeout setting. Overall, this tool is incredibly helpful for those looking to adjust and fine-tune specific Internet Explorer settings for use cases such as web server testing.
