ConfigurationOfZincHTTPComponents in Pharo 7

Hi Everyone,

Pharo 6 included ConfigurationOfZincHTTPComponents as part of the core
image, but it is no longer included in Pharo 7.

Can someone tell me where to load ConfigurationOfZincHTTPComponents
from, or what its replacement is?

In particular, I would like to load the WebSockets code.

Thanks very much,
Alistair
