The task is to use different proxy servers for different domains, pre-specifying which domains should be routed through which proxy server.

This solution restores the familiar practice of using a single browser for everything, eliminating the need to segregate specific types of websites into different browsers, each with its own pre-configured proxy.

1. Installing Clash for Windows

Download the latest version of Clash

1.1 Installation

Run the installer and open the application.

1.2 Creating a New Profile

Create a configuration file as follows, where you need to specify your proxy server parameters (IP, login, password).

Also, specify which domains should be opened through which proxy.

config_my.yaml

With the following content:

# config_my.yaml
mixed-port: 7890
allow-lan: false
mode: rule
log-level: info
external-controller: 127.0.0.1:9090

# Proxy Servers
proxies:
  # First proxy
  - name: "la_proxy"
    type: socks5
    server: first-proxy.tld
    port: 8449
    username: proxy_user
    password: proxy_password
    
  # Second proxy  
  - name: "corp_network"
    type: socks5
    server: second-proxy.tld
    port: 8449
    username: proxy_user
    password: proxy_passord

# Proxy Groups
proxy-groups:
  - name: "PROXY"
    type: select
    proxies:
      - "la_proxy"
      - "corp_network"
      - "DIRECT"

# Rules
rules:
  # Specific rules first
  - DOMAIN-SUFFIX,synay.net,corp_network
  - DOMAIN-SUFFIX,example.com,corp_network
  - DOMAIN-SUFFIX,2ip.ru,corp_network
  - DOMAIN-SUFFIX,my-second-office.com,la_proxy
  - DOMAIN-SUFFIX,corp.portal2.com,la_proxy
  
  # Last rule - everything else
  - MATCH,DIRECT

Load the configuration in the Profiles -> Import section.

1.3 Activate the Profile

Click on the profile to activate it, and also enable the proxy globally in the General settings tab.

General -> System Proxy -> On

To use the application continuously, also enable the following options:

General -> Start with Windows -> On

And also silent mode:

Settings -> Silent Start -> On

This configuration example, utilizing multiple proxy servers, allows you to work with several segregated corporate resources simultaneously in any browser (globally), whether it's an internal portal or a CRM.

Such a setup makes work convenient and comfortable, eliminating the need for constant switching. Furthermore, it allows you to restrict other transit traffic directly on the proxy servers.
