I've a little web server running on a NAS at home that I want to access with the Kindle 4 NT webbrowser (to display a calender). My router uses DynDNS so that I can access it via a URL like example.homeftp.net. The connection to the ISP is shortly interrupted every 24 hours so that the server gets a new IP every day.
When loading the site with the Kindle browser it works only as long as the Server IP doesn't change. After the IP changes the Kindle browser cannot access the server. Rebooting the Kindle does solve this problem for the next day. So my preliminary conclusion is that the browser doesn't respect the TTL information from the DNS server and caches the IP for a URL "forever".

Has anyone else observed this behavior and solved it?
Is there a configuration file entry that disables DNS caching?

I am using firmware 4.1.1 (jailbreaked with usbNetwork access).
