Summary
Name or dotted decimal Internet address of a proxy server.
Description
The ProxyHost property specifies the name or internet address of a proxy server. This property must be set before a session can be established through proxy server. Before connecting to a ftp
server through a proxy server, the application must also set the ProxyUser, ProxyPassword, ProxyPort and ProxyType properties. There are three possible ways of specifying the address of a proxy
server.
Machine Name
An application only needs to specify the name of the proxy server if the server is located on the same network as the local PC or if the internet address of the server is defined in the local host
table. If the proxy server is not on the local network, then the underlying protocol will route the traffic through a gateway. If the proxy server is not defined in the local host table, then the
underlying protocol will contact the domain server to resolve the internet address of the server.
Machine and Domain Name
An application needs to specify the machine name and the domain name if the proxy server is not located on the same network as the local PC. Fully domain qualified machine names are written from left
to right in ascending order (for example, genie.distinct.com). If both machine and domain names are specified, then the underlying protocol will contact the domain server to resolve
the internet address of the server.
Internet Address
Sometimes the user knows only the internet address of the proxy server that he or she wants to use. In this case, the internet address can be entered in the dotted decimal notation (for example,
127.43.101.12). If the proxy server identified by this address is not on the local network, then the underlying protocol will route the traffic through a gateway.
This property can be changed at design time and at run time before a connection has been established. There is no default value for this property.
Example
FTPClient.ProxyHost = ftp.distinct.com
FTPClient.ProxyPort = 80
FTPClient.ProxyUser = "anonymous"
FTPClient.ProxyPassword = "distinct"
FTPClient.ProxyType = PROXY_TYPE_HTTP
Result = FTPClient.Connect ("speedy.distinct.com", "santa", "north pole", "")
