This page provides information on how to set up a proxy connection. Overview Cosmos Browser requires internet connection to Chaos services to work correctly. When Cosmos Browser is installed in a network where all requests go through a proxy server, some proxy configuration should be applied.  By default, the Cosmos Browser detects the proxy connection automatically. On some occasions you might need to specify additional settings, such as proxy type, host, port, username and password. See below how to set the configuration.  Steps In the Cosmos Browser installation directory, find the  config.json  file. By default this file is installed in: Windows :  C:\Program Files\Common Files\Chaos\Cosmos macOS :  /Library/Chaos/Cosmos/ 2. Open the  config.json  file with a text editor and go to section  proxy .  Fill in the values of the the proxy related variables:  type:  – Specifies the proxy connection type, can have the following values: auto  – Default value, performs automatic proxy detection. http  – Used to set an http proxy connection type. none  – Used when there is no proxy and also, no need for automatic proxy detection. host: ""  – stores (in the brackets) the proxy host address. port: 0,  – stores the proxy port. user: "",  – stores (in the brackets) the user name. password: ""  – stores (in the brackets) the password. 3. Save your changes to the config.json file. 4. Restart the Cosmos Browser process.   In  Windows , go to the  Start menu  and type in  Stop Cosmos Browser  and then  Start Cosmos Browser . HTTP proxy can pass over HTTPS requests as well.
