【问题描述】：
今天，我正在寻求您的帮助，因为我在使用 Traefik (v2.4) 时遇到了路由问题，我觉得这是后者的错误。
我在 Debian 10 (Buster) 上使用 Docker v20.10.2 和 Docker Compose v1.25.0
我正在寻找这些重定向：
www.mywebsite.com
|____main-wordpress:80
www.mywebsite.com/blog
|____blog-wordpress:80
所以我有一个像这样组成的 docker-compose.yml（摘录）：

当只使用一个 WordPress，一切正常，路由按预期完成。
另一方面，当两个 WordPress 都在运行时，Traefik 在两者之间进行一种“负载平衡”，就好像它们在每个 WordPress 之上运行一样其他。 我查看了 Traefik 的访问日志，这正是发生的情况，请求在两个容器之间拆分，而与原始 URL 无关。
我不理解这种行为，即使我根据文档定义了避免这种行为的优先级，而且这些规则对我来说似乎很好。
你认为我错过了什么吗？我已经找了2天了，我没有看到：/
感谢那些帮助我解决这个问题的人:)
