i don't know of a list output. what i do is to use varnishlog or turn on debug 
headers:


open varnishlog, request a resource and see at the X-Varnish-Action Header


requesting a resource the first time that gets cached will give you

TxHeader     c X-Varnish-Action: FETCH (insert)

requesting it again will log

TxHeader     c X-Varnish-Action: HIT (deliver - from cache)



personally i'm using some combination with grep that gives me the headers i'm 
interested in:


For debugging all requests to a certain url (eg /test/test/image_mini) and see 
important headers::

varnishlog -c -o  RxURL '^/test/test/image_mini$' | grep -E "RxRequest|RxURL|
Host:|TxStatus|TxResponse|X-Varnish-Action"

run varnish with the -T option (eg "-T localhost:6182")

connet via telnet:

telnet localhost 6182

and call something like

url.purge /that-part/.*


to see whether to use www.example.org/that-part or just /that-part or any 
other fancy url (you might have a webserver rewrite urls for doing 
virtualhosting) you can use varnishlog again:

varnishlog -c -i RxURL



hope that helps
