我们目前正在使用互联网云提供商来托管我们的 SaaS 平台。该平台由防火墙 -> 云提供商 SLB -> -> Apache Web 服务器 -> HAPROXY SLB -> Liferay 平台组成
由于云提供商 SLB 存在问题,我们不得不使用 HAPROXY,这意味着我们无法使用它来平衡 Liferay 平台应用程序的负载。
我已经在我们的安全层中实现了 HAPROXY,并且它似乎能够相当充分地实现请求负载平衡。
但是在测试期间我们遇到了一个功能问题,即从 Web 门户选择一个子菜单导致应用程序挂起,使用 http 分析器我们看到传回用户浏览器的请求是 http 格式的,通过与软件供应商讨论得知,Liferay 应用程序有一些硬编码的 http 链接,而其他客户已经通过使用物理 NLB(如 F5)并将 http 流量重定向到 https 来解决此问题。

通过阅读论坛和其他网站,我们似乎应该使用 HAPROXY 将流量重定向到 https,但是无论我怎么尝试,我都无法让它工作。
这是我们的 HAPROXY 配置:

我尝试过按照列出的文章发布https://stackoverflow.com/questions/13227544/haproxy-redirecting-http-to-https-ssl和http://parsnips.net/haproxy-http-to-https-redirect/但这并没有什么区别。
我这样做是否正确,还是我们只是在试图实现不可能的事情?我希望我只是个白痴,你们中有人能给我指明正确的方向。
