Long WebSocket requests on encrypted connections may cause errors

Changelog Number	10279
Type	Bug
Status	Resolved
Affected Versions	Exasol 6.1.0, Exasol 6.2.0
Fix Versions	Exasol 7.0.0, Exasol 6.2.8, Exasol 7.0.rc1
Resolution Date	2020-06-23

When connected to Exasol using a secure WebSocket connection (wss://), requests with a long text length (>56KB) may cause errors.

For example, the error may be similar to the following error.

Unsupported WebSocket opcode

Disabling encryption will fix the problem (i.e. using 'ws://' instead of 'wss://').

 Please be aware that the connection will then be insecure.

The requests with a long text length will be handled correctly and no longer throw the above error.
