Hi
Is it possible to purge something from the cache via the CacheMgr.cgi
interface? I need to quickly remove any incorrect content from a
website that uses two reverse proxies as a caching layer..
thanks!
Not really. That is still on the wishlist.
Holding CTRL down while clicking the reload button in your browser will
clear out all objects for that page from every proxy in the path.
However this requires an HTTP standards-compliant proxy. Proxies using
the refresh_pattern override-* or ignore-* which warn about standards
compliance can block the updates. As can the http_port "ignore-cc"
option on reverse-proxies (thus a separate unflagged management port is
useful on reverse proxies).
If you have PURGE access permitted you can send a PURGE request for the
relevant URL.
squidclient -m PURGE -H '$vary_headers' $url
where $url is the URL being purged, and $vary_headers are what the
browser sent for each Vary: listed header to get the object cached.
Recent releases will reveal what those where in the cachemgr object
report, otherwise its a blind guess.
Alternatively you could use the squidpurge tool to find and remove
things.
