[cool to know that some people know about this :-)]

They are two possibilities:

a) You want to take full control of wether or not the proxy is
connected. It starts disconnected, when your filter runs, you connect
it.

b) You leave it to the cache filter (a better, but more difficult
approach). Your filter should then get a pointer to the cache filter
by using:
w3c.www.protocol.http.HttpManager::getGlobalFilter
and then you get/set the disconnected property [in fact, because
Jigsaw uses observable properties, I am not sure you even need a call
to getGlobalFilter...get the properties from the manager (at
initialize time), and just set the
"w3c.www.protocol.http.cache.connected" property, this should work by
its own]

Anselm.
