非標準埠上的HTTP/HTTPS連接，用於專用出口IP地址和VPN

非標準埠（不是80/443）上的HTTP/HTTPS連接必須從as a Cloud Service中，但它們不需要任何特殊 portForwards 規則，並可AEM以使用 AEM_HTTP_PROXY_HOST。 AEM_HTTP_PROXY_PORT。 AEM_HTTPS_PROXY_HOST, AEM_HTTPS_PROXY_PORT。

代碼示例

此Java™代碼示例是OSGi服務的示例，該服務可以在AEMas a Cloud Service中運行，該在8080上與外部Web伺服器建立HTTP連接。 與HTTPS Web伺服器的連接使用 AEM_HTTPS_PROXY_HOST 和 AEM_HTTPS_PROXY_PORT 而不是 AEM_HTTP_PROXY_HOST 和 AEM_HTTP_PROXY_PORT。
