grammar (martin)		5.20: Bug 81: Optionally keep symbolic link name in path instead of resolving it with SFTP protocol (martin)
	Line 12:		Line 12:

	Use //Preferred SFTP protocol version// to configure maximal version of SFTP protocol that WinSCP will attempt to use. WinSCP will seamlessly downgrade to any lower version that the server supports. The only reason, that you may want to change the option for, is bug either in SFTP server or WinSCP itself specific to particular version of the protocol.

		+	Adhering to the SFTP specification, when changing directory, WinSCP asks the SFTP server to canonicalize the new path.((Using the ''SSH_FXP_REALPATH'' request.)) With OpenSSH (and possibly other) SFTP servers this has side effect that the symbolic links in the path are resolved, what can complicate navigation back. Some minor SFTP servers even have this functionality broken. For either of these reasons, you may want to turn the canonicalization off, by unchecking //Canonicalize paths on the server//. &beta_feature

	By default SFTP has option //Allow SCP fallback// enabled. With the option enabled, WinSCP tries to find SFTP server and when it fails, it initiates SCP protocol. Note that, when fallback is disabled, WinSCP tries harder using non-standard methods to find the SFTP server. It is necessary to allow SFTP on SSH-1 server (read [[requirements#sftp\|SFTP requirements]] for more). You can see the protocol actually used on the [[ui_fsinfo\|Server and Protocol Information Dialog]]. SCP fallback cannot be combined with a custom path to SFTP server binary.
