Script to Clear a Page from Varnish Cache
The script below will purge/ban a page from the varnish cache and then re-cache the page by curling it
#!/bin/bash cmd="varnishadm -T 127.0.0.1:6082 -S /etc/varnish/secret" site="http://www.briansnelson.com" page="$1" if [ "$page" != "" ]; then echo -e "\nPurging old version from cache:" echo "-------------------------------" $cmd ban.url "$page$" | sed '/^$/d' $cmd ban.list | head -n 2 echo -e "\nPopulating cache with new page content:" echo "---------------------------------------" curl -sL -w "%{http_code} %{url_effective}\n" $site/$page -o /dev/null else echo Error: please provide a URL to purge.. fi
Once you have it download/setup on your system you will want to give the execute permission
chmod +x recache-varnish.script
How to use the script
bash recache-varnish.script <page to be purged/ban>
To clear this page from the varnish cache you would run:
bash recache-varnish.script Script_to_Clear_a_Page_from_Varnish_Cache
