Varnish is being used in a Wordpress website.

I would like to purge Varnish for a single URL instead of a whole domain.

With this command I can restart Varnish for the whole domain:

varnishadm -T :6082 -S /etc/varnish/secret 'ban req.http.host ~ \"http://www.foo.com\" && req.url ~ \"^/\"'

However I would like to purge varnish only for a single url.

Ex: www.foo.com/url_to_be_purged

I've tried the previous command replacing it with the single URL:

varnishadm -T :6082 -S /etc/varnish/secret 'ban req.http.host ~ \"http://www.foo.com/url_to_be_purged\" && req.url ~ \"^/\"'

But it didn't work, the URL still was a HIT in Varnish.

Any ideas of how can I achieve this?


As suggested ghloogh's answer, I've tried the following command:

varnishadm -T :6082 -S /etc/varnish/secret ban "req.http.host == http://www.foo.com && req.url == http://www.foo.com/url_to_be_purged"

I've also tried this variation:

varnishadm -T :6082 -S /etc/varnish/secret ban "req.http.host == http://www.foo.com && req.url == /url_to_be_purged"

But I still get a HIT in the URL and the data is not updated

    man, stop using scheme (http:// or https:// or ftp:// or other) in hostname :) your command should be: varnishadm -T :6082 -S /etc/varnish/secret ban "req.http.host == www.foo.com && req.url == /url_to_be_purged"

  • How can we purge URL by pattern, say all matches for /foo/bar/ab*

You don't need to specify scheme for hostname and you may use strict match instead of regex:

varnishadm -T -S /etc/varnish/secret ban "req.http.host == example.com && req.url == /some/url/"

    The other answer had the quote in the wrong place. > varnishadm -T -S /etc/varnish/secret "ban req.url == /url_to_be_purged"

You can try the following:

sudo varnishadm -S /etc/varnish/secret  -T "ban req.url ~ \"http://example.com/testimage.png$\""

worked for me.

    This doesn't add anything but sudo to the other answer. This might be better as a comment. Jun 26 '17 at 12:52
  • you saved my day! To solve it is necessary to consider the slashes before the quotes May 12 '20 at 8:44
