Purge and cache content mist.

Thank you.

About the url.purge, should I understand that url.purge doesn't manage hosts
 so url.purge /that-part/.* will purge  http://onedomain.com/that-part/* and http://otherdomain.com/that-part/* ?
Can I use onedomaine\.com/that-part/.* to purge only '/that-part/' in that host :) ?

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

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|

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
