使用HTTP和REGEX清除varnish [英] Varnish purge using HTTP and REGEX

问题描述

我想使用HTTP清除我的清漆的元素。此http调用是从后端服务器在清漆本身后面触发的，因此后端服务器不具有其他访问权限，只有HTTP。

I want to purge Elements of my varnish using HTTP. This http call is triggered from a backend server behind the varnish itself, so the backend server has not other access but HTTP.

我已根据ACL实施了以下清除规则：

I have implemented the following purging rules with the according ACL which work fine for

curl -X PURGE http://www.example.com/image/123/photo-100-150.jpg

但我希望能够使用Regex通过HTTP清除网址

but I want to be able to purge an URL via HTTP using Regex

curl -X PURGE http://www.example.com/image/123/*.jpg

以在上传新图片后清除此图片的所有缩放版本。是否有办法？

That way I want to clear all scaled version of this image once a new has been uploaded. Is there a way?

推荐答案

请尝试：

3.0及以上。

vcl_recv {
    if (req.request == "PURGE") {
             if (!client.ip ~purge){
                     error 405 "Not allowed";
             }
     ban("req.http.host == " +req.http.host+" && req.url ~ "+req.url);
     error 200 "Ban added";

    }
