Receive Text up to a Matching Sequence

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatch, which receives bytes until an exact byte sequence is found. The match string is encoded using StringCharset and compared byte-for-byte.

# Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
# connection succeeds; the 4th is the maximum time to wait, in milliseconds.

my $success = $socket->Connect('example.com', 5000, $bTls, $maxWaitMs);

# Send a request using a simple application-defined text protocol in which each message ends with a
# CRLF.
