SocketTools 6.0 introduces support for the SSH protocol, adds
several new features and a number of improvements which makes
Internet development even easier. The following is an overview of
some of the the new features:
- Support for the Secure
Shell (SSH) protocol has been added to the SocketTools Secure
Scripting Edition. Applications can establish secure, encrypted
connections to a server and execute commands remotely or create an
interactive terminal session. The interface for the SSH component
was designed to be similar to the Telnet component, making it easy
for developers to add support for SSH to an existing
application.
- Support for secure file transfers using SSH (SFTP) has been
seamlessly integrated into the FTP component. In most cases, the
only thing that an existing application needs to do is establish a
connection on the default SSH port, or specify a single option when
connecting to the server. A SocketTools Secure Scripting Edition
license is required to use the security features in the FTP
object.
- The Mail Message component has been expanded to provide storage
methods which enable an application to store, retrieve and search
multiple e-mail messages on the local system. The application can
use the OpenStore method to
create and manage a local mailbox, similar to how many mail clients
store messages that have been downloaded from a mail server.
- Automatic file type detection has been added to the FTP
component. This enables the component to automatically set the
correct file transfer mode based on the type of file being uploaded
or downloaded, without the application explicitly specifying if the
file is text or binary. It is also possible to register your own
custom file types using the AddFileType
method.
- Automatic file verification has been added to the FTP
component. The component can automatically verify that the file on
the local system is identical to the file on the server using an
MD5 hash or CRC-32 checksum after it has been uploaded or
downloaded. The file verification process can also be performed
directly by the application using the VerifyFile method.
For example, this can be used to determine if it is necessary to
upload a file depending on whether or not the contents have
changed.
- Support for virtual hosting has been added through an option to
the Connect
method. This allows the component to be used with servers that are
configured to host multiple domains using the same external IP
address.
- Improved support in the HTTP component for posting XML data to
a server, including the ability to post XML data and retrieve the
response from the server in a single method call. The new PostXml method makes it
easier for applications to submit XML data to a server, without
having to worry about setting the correct content type or transfer
encoding.
There have also been general improvements in overall performance
and efficiency with FTP and HTTP transfers, decreasing the overall
transfer times for large files. The core message parsing code in
the MIME component has also been improved, enabling it to
automatically correct problems with malformed messages, or messages
which do not strictly conform to the RFC 822 and/or RFC 2045
standard message formats. The POP3 and IMAP4 components also
provide better support for managing a large number of messages on
the mail server.
