Proxy Setting Guide

In order to allow OnScale servers to communicate with your internal network servers, you may be required to set up OnScale to go through your company internal proxy server

This guide will detail how to enter your company proxy server settings in OnScale to allow a smooth upload and download of your simulation data.

What is a proxy server?

A proxy server acts as a gateway between you and the internet. It’s an intermediary server
separating end users from the websites they browse. Proxy servers provide varying levels of
functionality, security, and privacy depending on your use case, needs, or company policy.
If you’re using a proxy server, internet traffic flows through the proxy server on its way to
the address you requested. The request then comes back through that same proxy server (there
are exceptions to this rule), and then the proxy server forwards the data received from the website to you.


Why going through a proxy server?

Proxy servers act as a firewall and web filter, provide shared network connections, and cache
data to speed up common requests. A good proxy server keeps users and the internal network
protected and provides a high level of privacy.

How does a proxy server operate?

A proxy server is basically a computer on the internet with its own IP address that your
computer knows. When you send a web request, your request goes to the proxy server first. The
proxy server then makes your web request on your behalf, collects the response from the web
server, and forwards you the web page data so you can see the page in your browser.
When the proxy server forwards your web requests, it can make changes to the data you send
and still get you the information that you expect to see. A proxy server can change your IP address, so the web server doesn’t know exactly where you are in the world. It can encrypt your data, so your data is unreadable in transit. And lastly, a proxy server can block access to certain web pages, based on IP address.

A proxy server is a computer with its own IP and port that you can connect to and thus
requires the following information:


  • Hostname: This is either the address of your internal network proxy such as or its IP address (ask your IT department to find out this information)
  • Port: This is the communication port used to communicate with your proxy server (ask your IT department to find out this information)
  • Username: This is your internal company "username" used to login to your proxy server
    (ask your IT department to find out this information)
  • Password: This is your internal company password which correspond to your internal
    username (ask your IT department to find out this information)
