some.host.com is a Virtual Host. It has a Web Server External App configured: - Name: another.host.net - Address: another.host.net:80 - Max Connections: 50 - Initial Request Timeout (secs): 2 - Retry Timeout (secs): 0 - Response Buffering: No And it has Rewrite enabled with the following rule: RewriteRule ^/(.*)$ http://another.host.net/$1 [p] This works fine when I restart lsws, but after a while, if some.host.com changes IP address, it stops working. i.e. lsws seems to keep trying to use the previous IP address, and all requests start returning 503. Is there any way I could force lsws to refresh it's DNS cache for that redirect? Thanks.
