Use SOCKS4A feature of requesting that the proxy should resolve host-names.
Namespace: EnterpriseDT.Util.SocksAssembly: edtFTPnetPRO (in edtFTPnetPRO.dll) Version: 9.4.0.40
Syntax
Remarks
The SOCKS4 protocol requires host-names to be resolved on the client-side.
In some cases this is not feasible, so SOCKS4A introduced an extension which
allowed name-resolution to be performed on the proxy instead. If this flag
is set then the SOCKS4A extension will be employed thus preventing the
attempt to resolve host-names on the client. The default is false.
