Configuring system proxies You can use system proxy settings with certain Horizon components via the use-system-proxy or useSystemProxy parameters. To configure system proxy servers, set some or all of the following properties: Property Description Default http.proxyHost Hostname or IP address of proxy server to use for plain HTTP requests. None http.proxyPort TCP port of proxy server to use for plain HTTP requests. 3128 https.proxyHost Hostname or IP address of proxy server to use for HTTPS requests. None https.proxyPort TCP port of proxy server to use for HTTPS requests. 3128 http.nonProxyHosts Pipe-separated list of hostnames or IP addresses which bypass HTTP proxying. None https.nonProxyHosts Pipe-separated list of hostnames or IP addresses which bypass HTTPS proxying. None Depending on the JVM in use, the properties http.proxyUser, http.proxyPassword, and their https.* equivalents may enable the use of proxy servers that require authentication. Setting these properties may have unintended effects. Use with care. System Properties Configuration Tester
