Configuration Syntax

user daemon

listener 127.0.0.1 443 {
    protocol tls
    table "TableName"
}

table "TableName" {
    # Match exact request hostnames
    example.com 192.0.2.10      4343
    example.net 2001:DB8::1:10  443
    # Or use PCRE to match
    .*\\.com    2001:DB8::1:11  443
    # Combining PCRE and wildchard will resolve the hostname client requested and proxy to it
    .*\\.edu    *               443
