+"""TLS rehandshake test
+
+Test is using TLS proxy with rehandshake. When queries are sent, they are
+simply forwarded. When the responses are sent back, a rehandshake is performed
+after every 8 bytes.
+
+It is expected the answer will be received by the source kresd instance
+and sent back to the client (this test).
