ATE vs Server WEBCACHE
By default, WEBCACHE operates on the server side. But in many cases it makes as much sense for it to operate on the client side, which you can activate adding the ATE option to your list of SET WEBCACHE options. Note that if you want to assign different options and/or repository directory to ATE, use the following sequence:
.SET WEBCACHE REPO <repo for ATE>
.SET WEBCACHE ENABLE,<options...>,ATE ! forward options & repo to ATE
.SET WEBCACHE REPO <repo for server>
.SET WEBCACHE ENABLE,<options...> ! set server options only
