我们正在尝试将Varnish添加到我们的Woocommerce设置中并遇到一些麻烦。
在产品页面上（例如/产品/电视），如果按下＆＃34;添加到购物车＆＃34;按钮，您现在可以按预期重定向到购物车页面，但该商品尚未添加到购物车中 但是，如果您在登录帐户时执行相同的操作，它将正常工作。我已经在下面发布了我的varnish.vcl，如果有人对什么是错误有任何见解，请告诉我。

我在这里找到了解决这个问题的方法： https://guides.wp-bullet.com/fix-empty-cart-with-woocommerce-redirect-to-checkout-varnish-4/
基本上，当您将项目添加到购物车时，Woocommerce会发出302重定向并将您发送到购物车（您可以从设置中禁用此行为）。在Varnish中，您必须确保在发生此事件时不要从后端响应中删除任何Cookie。
$(function(){
$('.select-another-button').each(function(){
$(this).bind('click', function(e){
$('#message').show()
setTimeout(function(){ $('#message').hide() }, 300000);
e.preventDefault();
fileBrowser(this);
return false;
});
});
});
