Squid proxy scheduling

[mcmonap]

Hi

I think that @Fright suggested https://forum.opnsense.org/index.php?topic=22700.0 that scheduling proxy exclusions (for example gaming before school) could be achieved by modifying the squid.conf.  This makes sense but the file header says it is auto-generated.  Can someone advise when the file is auto-generated please?  Is it only during modification in the GUI or is when the service restarts or when OPNsense restarts or something else entirely.  Hopefully it is the first and I can just keep my fingers out of the GUI.

Thanks.
