<hr />
<p>This class defines an interface for controlling the behavior of
paramiko when using the <a href="paramiko.SFTPServer-class.html"
class="link">SFTPServer</a> subsystem to provide an SFTP server.</p>
<p>Methods on this class are called from the SFTP session's thread, so
you can block as long as necessary without affecting other sessions (even
other SFTP sessions). However, raising an exception will usually cause
the SFTP session to abruptly end, so you will usually want to catch
exceptions and return an appropriate error code.</p>
<p>All paths are in string form instead of unicode because not all SFTP
clients & servers obey the requirement that paths be encoded in
UTF-8.</p>
