Clear the SFTP Session Log

Demonstrates the Chilkat SFtp.ClearSessionLog method, which clears the in-memory text stored in the SessionLog property. It takes no arguments.

Background: With session logging enabled, the SessionLog accumulates a running record of the session's activity that is invaluable for diagnosing a failed transfer. Over a long-lived session that log grows unbounded, so clearing it frees memory — and, more usefully, lets you capture the log for one specific operation in isolation by clearing it just before and reading it just after.
