# Network Object The Network object provides network functionality and information. Members Table The following table lists the members provided by the Network object.
Members
Collections | Description
Downloads | Contains all downloads.
InternetAddresses | All local IP addresses.
Properties | Description
FullyQualifiedDomainName | Fully qualified domain name.
Methods | Description
CheckInternetConnection | Returns whether an internet connection exists.
CreateHTTPPost | Creates a HTTPPost object.
Events | Description
CheckInternetConnectionComplete | Fires when the internet connection check has been completed.
Remarks This object is available through the main object SiteKiosk. Use the Network object to create and send a HTTP request or to receive information about the network and downloads. In combination with the ScriptDevice object the Network object provides the possibility to control the SiteCash account from another computer through HTTP. Note that the path of a file using SiteKiosk objects must be allowed in the SiteKiosk configuration (Security -> Access -> URL's With Script Permission) if it is not a browser skin file. Examples The following example represents a complete payment solution that uses the ScriptDevice object and the Network object to read and set values of an account that is saved on a server. This is the login dialog. The soure code of the script device dialog which is defined in the SkinDef file of the browser skin should be replaced with this one. The payment simulation dialog box of the SiteKiosk Payment Module must be enabled in the SiteKiosk configuration.
