but how would i proceed if i want to know what actually is in the cache?
e.g. view a cached version of an URL: http://mydomain.com/somepage
Fetch it with a HTTP client.
thanks andreas,
yes, i know i can fetch it with a http client to see the cached version ;)
but i'm looking more into finding out what URL's there are in the cache
to find the culprits as i never know what clients out there request.
in the past i was working with other caching systems, like PEAR Cache
Lite, which is based on PHP.
and there I can easily see what URLs are in the cache. this way i could
easily see the 'wrong' cached URLs and re-adjust my caching system to
get a high positive hit rate.
for example, i got URL like:
http://mydomain.com/?param=foo&doe=john
but anyone out there is allowed to request stuff like:
http://mydomain.com/?param=foo&doe=john&culprit=this&anotherculprit=that
the additional params the client sends actually do nothing but as far as
I understood, varnish will cache based on URLs ... so ending up with 2
cached versions ...
so ... to spot those culprits i would like to know if there is a list of
URLs / cached objects in varnish that i can view ... investigate
to then adjust the vlc to filter out those bad cached to get a higher
positive hit rate.
does this make sense? is something like that available in varnish 5?
thanks & greetings
becki
