Feature request: Send custom data from client to server events

Not that easy to implement, I know:)

The server events system is great and I am automatizing lots of actions with it.
However we are always restricted to what variable is provided to the event.

In an ideal world, I would be able to send from the client some additional custom data to the events.

For example with the onBind event, the client could add in the request a small json string containing additional information available only to the client:

vhclient -t "USE,server1.123,custom_data={'foo': 'bar', 'version': 3, .... }"

Then received by the event in a $CUSTOM_DATA$ variable.

.

Is this for any command, or just the USE?

Specifically for the USE command - there is an optional 3rd field to supply a password.

However the $PASSWORD$ field itself can be split into two separate fields with a backslash delimiter. The first part is the client id and is not MD5 encoded e.g

You can can insert your custom data into the Client ID field then backslash then any single character e.g 0.

You will receive the custom data as the $CLIENT_ID$ field in the ClientAuthorization script exactly how you specify it.

E.g

"USE,abcd.1234,custom_data={'foo': 'bar', 'version': 3, .... }\0"

In the script the $CLIENT_ID$ equals custom_data={'foo': 'bar', 'version': 3, .... }

Not sure if that suits your usecase, but for the general case for any event it would be difficult to make a change to the syntax and make it forward and backward compatible with existing scripts.

.

Actually my use case is on the "STOP USING", so the "onUnbind" event :)

But this workaround with the password is an interesting trick I will keep in mind!
