how can I get the hiden input value I have that tell varnish that we
have a new post?
<input type="hidden" name="canpurge" value="/topic/123-my-topic/" />
I was thinking of something like this:
sub vcl_recv {
if (req.request == "POST" && FORM.FIELD == "canpurge) {
purge req.http.host == example.com && req.url ~
^FORM.CANPURGE.VALUE.*$
}
}
Nuno:
Varnish can't see the body of the response. However, if you're able to
change the response, you can just add an HTTP header with this
information. Then, in vcl_fetch (which is where the HTTP request is
sent to the backend), you can probably add something like:
sub vcl_fetch {
if (beresp.http.x-purgepattern) {
purge("obj.http.host == example.com && req.url ~ "
beresp.http.x-purgepattern);
}
}
