`GetLinkTags`	`0\|1`	`-getlinktags`	Activates download of linked stylesheets for `GETALL` requests: `0` - disabled `1` - enabled (if the target page contains a `link` tag with attribute value `rel=stylesheet`, the monitor attempts to download the resource referred to by the `link` tag's `href` attribute)
`HostnameLookupPreference`	string	`-hostnamelookuppreference`	Determines which IP version, IPv6 or IPv4, is applied to the supplied host name. The possible values are: `4Then6` selects IPv4 and then IPv6. Uses IPv4 addresses if they are available. If no IPv4 addresses are found, IPv6 addresses are used. `6Then4` selects IPv6 and then IPv4. Uses IPv6 addresses if they are available. If no IPv6 addresses are found, IPv4 addresses are used. `4Only` selects IPv4 only. Uses IPv4 addresses only. If there are no IPv4 addresses, the poll returns an error. `6Only` selects IPv6 only. Uses IPv6 addresses only. If there are no IPv6 addresses, the poll returns an error. `6Or4` selects either IPv4 or IPv6. Uses the first address returned from the host name. Default: `4Then6`
`Ipv6Address`	integer	`-ipv6address`	The local address to bind to as an origin for HTTP requests when using HTTP IPv6. Default: no address
`NoParseExtensions`	string	`-noparseextensions`	A comma-separated list of file extensions indicating file types that the monitor will not parse and instead only download.
