| Value |
Description |
| fileOptionNoCache |
This instructs an HTTP server to not return a cached copy of
the resource. When connected to an HTTP 1.0 or earlier server,
this directive may be ignored. |
| &H1000 |
fileOptionSecureImplicit |
This option specifies the client should immediately
negotiate for a secure session upon establishing a connection
with the server. This is the default method for connecting to a
secure HTTP server and may also be used with FTP servers that
accept secure connections on port 990. |
| &H2000 |
fileOptionSecureExplicit |
This option specifies the client should use the AUTH
server command to tell an FTP server that it wishes to explicitly
negotiate a secure connection. This requires that the server
support the AUTH TLS or AUTH SSL commands. Some servers may not
require this option, and some may require the option only if a
port other than 990 is specified. If this option is specified,
the Secure property will automatically be set to
True. |
| &H4000 |
fileOptionSecureShell |
This option specifies the client should use the Secure
Shell (SSH) protocol to establish the connection. This option
will automatically be selected if the connection is established
using port 22, the default port for SSH, and is only required if
the server is configured to use a non-standard port number. |
| &H8000 |
fileOptionSecureFallback |
This option specifies the client should permit the use of
less secure cipher suites for compatibility with legacy servers.
If this option is specified, the client will allow connections
using TLS 1.0 and cipher suites that use RC4, MD5 and SHA1. |
| &H40000 |
fileOptionPreferIPv6 |
This option specifies the client should only attempt to
resolve a domain name to an IPv6 address. If the domain name has
both an IPv4 and IPv6 address assigned to it, the default is to
use the IPv4 address for compatibility purposes. Enabling this
option forces the client to always use the IPv6 address if one is
available. If the domain name does not have an assigned IPv4
address, the IPv6 address will always be used regardless if this
option is specified. |
| &H100000 |
fileOptionHiResTimer |
This option specifies the elapsed time for data transfers
should be returned in milliseconds instead of seconds. This will
return more accurate transfer times for smaller files being
uploaded or downloaded using fast network connections. |
| &H200000 |
fileOptionTLSReuse |
This option specifies that TLS session reuse should be enabled
for secure data connections. Some servers may require this option be
enabled, although it should only used when required. This option
is only valid for secure FTP (FTPS) connections and is not used
with SFTP or secure HTTP connections. See the
remarks below for more information. |
