This article explains how to perform a connectivity test from the ProxySG CLI by sending an HTTP GET request to an Origin Content Server (OCS). A successful HTTP GET request should result in HTTP code 200 or HTTP code 302 (redirection) indicating of successful connections from ProxySG to OCS. Other codes, for example: 401 unauthorized, or 502 bad gateway, may indicate deployment or configuration issues.
Note: Some websites operate only HTTPS, so you should expect to receive an HTTP response code 302 for redirection when testing with such a site.
To perform the test, SSH into the ProxySG CLI and issue the following command: test http get www.google.com
Note the HTTP GET results on the last line in the output.
