(PowerShell) Demonstrates KeepSessionLog and SessionLogThe Chilkat Socket component provides properties for keeping a session log making it possible to see the exact bytes received and sent on a TCP/IP or SSL/TLS connection. To enable session logging, set the KeepSessionLog property = $true. The SessionLogEncoding property controls how binary, non-printable bytes are represented in the log. There are two possible settings: Possible values are "esc" and "hex". The default value is "esc". When set to "hex", the bytes are encoded as a hexidecimalized string. The "esc" encoding is a C-string like encoding, and is more compact than hex if most of the data to be logged is text. Printable us-ascii chars are unmodified. Common "C" control chars are represented as "\r", "\n", "\t", etc. Non-printable and byte values greater than 0x80 are escaped using a backslash and hex encoding: \xHH. Certain printable chars are backslashed: SPACE, double-quote, single-quote, etc.
