Introduction
Your EdgeVis Server will connect to the Central Licensing Service, using standard web protocols (SSL over port 443).
Likewise, users who want to take advantage of a third-party SSO provider will usually find that their server is required to connect to an external web service to authenticate their users.
By default, EdgeVis Server will attempt to directly connect to these servers, however many organisations require all web traffic to go through a proxy server, and consequently block direct access to the internet for all standard web traffic.
The following steps with configure your server to use a web proxy when making these requests.
Steps
Install EdgeVis Server using the standard installation instructions, but stop before attempting to authenticate your server with CLS.
Log in to your EdgeVis Server's web interface as a System Administrator.
From the home page, goto the All server settings -> Multi-site resilience page.
The page will either already show that multi-site resilience is already enabled, in which case, proceed to the next step.
Otherwise hit Enable multi-site resilience button on the right.
By default, on v9.1 servers, your server will hide most of the advanced networking features. By enabling multi-site resilience, you will now have access to additional settings.
It will not change the operation of your current server, and you are not obliged to add additional servers to create a cluster.
The page will list each of the servers in your cluster. By default there should only be one listed, but clusters will list multiple servers.
For each server listed, you must:
Click on the server
Select the Edit this server's proxy settings button on the right.
Tick the Use an HTTP proxy button
Enter the URL of your proxy server, then Submit
Ensure you've set a proxy for all your servers listed, then continue with configuring CLS/SSO as per the standard instructions.
