How to set the proxy server system variables

The database that needs to be proxied is MySQL. The system variable values ​​of the master and slave databases are both 1（for lower_case_table_names）


but after connecting to the proxy server, the value is 0. I don't know where to set it.

Variable 'lower_case_table_names' is a read only variable


I set the value in the console window connected to the proxy server, but there was no change

Based on the above, I hope to find a way to set this system variable

No source file or test is named. Start by reproducing the lower_case_table_names mismatch through the MySQL proxy and compare the proxy and master/slave system-variable behavior, including the read-only error. Done means identifying whether the variable is configurable through the proxy and documenting the supported setting or limitation.
