Which Proxy Script and Template to Use and Why

Proxy servers act as intermediaries between your device and the websites you visit. To fine-tune how your device interacts with the proxy, there are two approaches: proxy scripts and templates. But what exactly are they, and which one should you use?

Understanding Proxy Scripts

Imagine a tiny program that sits between your device and the proxy server. This program, known as a proxy script, dictates how traffic is routed. They offer granular control over proxy behavior.

What proxy scripts can do:

    • A script can specify which websites bypass the proxy entirely (think internal company resources) and which ones are routed through it.
    • Some proxy servers require login credentials. Scripts can automate this process, saving you time and effort.
    • Advanced scripts can even modify content on the fly, such as blocking ads or injecting custom elements.

    However, proxy scripts come with some drawbacks:

    • Writing and maintaining scripts requires programming knowledge, making them less user-friendly.
    • Malicious scripts can compromise your system. Ensure they come from trusted sources like established developer communities.

Popular Scripting Languages


Python’s flexibility allows for intricate logic and advanced features like content filtering or injection. It also integrates well with various libraries for interacting with other network tools or system functionalities.

Best For: Users with programming knowledge seeking granular control and advanced features. Ideal for scenarios requiring automation of complex proxy behaviors.



Bash scripts offer a lightweight solution for setting up basic proxy connections on Linux systems. They can automate repetitive tasks, saving time when scripting proxy configuration across multiple devices.

Best For: Linux users comfortable with the command line who need a simple way to manage basic proxy settings.  Ideal for situations where automation of repetitive proxy tasks is desired.



UDP can handle the unique requirements of UDP connections used for applications like online gaming or video conferencing.  They can be tailored for specific protocols or proxy server functionalities that don’t rely on TCP connections.

Best For: Advanced users managing proxy connections for real-time applications requiring UDP protocol handling. Ideal for scenarios involving specialized proxy servers or protocols that don’t utilize TCP.

Understanding Proxy Templates

Proxy templates offer a pre-defined script structure with variables you can customize. Think of them as fill-in-the-blank forms for proxy configuration.

The benefits of templates include:

  • Templates are generally simpler to set up than writing scripts from scratch.
  • They provide a consistent way to configure proxies across different devices.
  • Templates from reputable sources are generally less risky than custom scripts.

On the other hand, templates have limitations:

  • They may not offer the same level of granular control as custom scripts.
  • Some advanced features might not be available in templates.

Popular Proxy Templates Options

Proxy Auto-Config (PAC) Files

PAC files define rules specifying which websites bypass the proxy and which ones are routed through it. A single PAC file can be deployed across a network, ensuring consistent proxy settings for all users.

Best For: Users seeking a user-friendly way to define basic proxy routing rules. Ideal for network administrators deploying consistent proxy configurations across multiple devices.


WPAD (Web Proxy Auto-Discovery Protocol)

WPAD allows devices to locate a proxy server automatically using DHCP. No manual configuration is needed as the device retrieves proxy settings automatically.

Best For: Network environments where automatic proxy discovery is desired for a centralized and streamlined user experience. Ideal for scenarios where minimizing manual configuration steps for users is a priority.


Basic Authentication Templates

These templates provide a structured way to input your credentials for the proxy by allowing you to set up username and password for proxy servers requiring authentication. Pre-defined templates simplify the process of entering login details for secure proxies.

Best For: Users who need to connect to proxies requiring authentication in a straightforward manner. Ideal for situations where ease of use and a quick way to configure proxy authentication are important.

So, which one should you use?

The choice depends on your technical expertise and needs:

  • For basic proxy configuration with user-friendliness in mind, opt for templates.
  • If you require intricate routing rules or advanced functionalities, scripting is the way to go, but make sure you possess the programming skills.
Security Reminder: Always download scripts from trusted sources to avoid malware. For UDP connections beyond gaming or conferencing, consider consulting network documentation for specific use cases.
