An HTTP Custom (.hc) configuration file is a specialized script used for network manipulation, tunneling, and bypassing restrictions. It's commonly employed with tools like HTTP Custom, HTTP Injector, and other similar apps. These configurations enable users to alter HTTP requests, use proxy servers, and modify headers, providing a versatile way to customize how data is sent and received over a network. This guide explains what a .hc file is, how to create one, its structure, and essential guidelines for ensuring your configuration is compliant and functional.
What is an HTTP Custom File?
An .hc file serves as a configuration file for network tunneling tools, allowing users to bypass firewalls, access restricted content, or optimize network connections. It contains a series of commands or instructions, usually formatted in a structured way to direct how HTTP requests and responses should be handled.
These files are often used in:
VPN-like connections: To route traffic through proxies or servers.
Header modification: Altering HTTP headers to appear as different clients.
Payload manipulation: Adding data to HTTP requests.
Bypassing ISP Restrictions: Circumventing geo-blocks or data caps.
Structure of an HTTP Custom (.hc) File
An .hc file consists of various sections, each serving a specific purpose. Below is a breakdown of typical sections you might include in an .hc file:
1. General Settings
This section defines basic parameters, such as proxy settings and connection type.
Example:
[general]
proxy = 127.0.0.1:8080
2. Request Configuration
This part sets the HTTP method, URL, and custom headers.
Example:
[request]
method = GET
url = http://example.com/data
header = User-Agent: CustomClient/2.0
header = X-Forwarded-For: 1.1.1.1
3. Response Handling
This section manages how responses are treated. You can filter for specific status codes or responses.
Example:
[response]
status_code = 200
4. Payload Injection
If the app supports it, payload sections can add or alter data within requests.
Example:
[payload]
data = "Injected data string"
Steps to Create and Use a .hc File
1. Install an HTTP Custom App
Download and install HTTP Custom or a compatible app from the Google Play Store or a trusted source.
2. Create the Configuration
Use a text editor like Notepad (Windows), VS Code, or any mobile text editor to write the .hc configuration. Make sure the file extension is .hc.
3. Load the File
Open the HTTP Custom app.
Import the .hc file using the app's import feature.
The app will parse the configuration and prepare it for connection.
4. Connect and Test
Start the connection.
Verify that the connection behaves as expected (e.g., bypasses restrictions, routes through proxies).
Example of a Full .hc File
Here’s a simple, complete example of a .hc file that routes traffic through a proxy and modifies headers:
[general]
proxy = 192.168.1.1:8080
[request]
method = GET
url = http://example.com/api/data
header = User-Agent: CustomUserAgent/1.2
header = X-Real-IP: 192.168.1.100
[response]
status_code = 200
This configuration specifies:
A proxy server (192.168.1.1:8080).
A GET request to http://example.com/api/data.
Custom headers for User-Agent and X-Real-IP.
A condition to handle responses with a 200 status code.
Best Practices for .hc Files
1. Avoid Copyrighted Content
Ensure all URLs, headers, and payloads used are either public domain or your own creation. Avoid proprietary or copyrighted configurations.
2. Security Considerations
Do not expose sensitive information such as personal IP addresses or authentication tokens.
Use encryption where possible.
3. Compliance and Legality
Ensure your use of .hc files complies with local laws and your ISP’s terms of service.
Bypassing security measures may violate terms, so proceed with caution.
4. Testing and Debugging
Test your .hc file on different networks to verify functionality.
Use debugging tools to monitor network traffic and troubleshoot issues.
Common Use Cases for .hc Files
1. Bypassing School or Workplace Restrictions
Route traffic through a proxy to access blocked websites.
2. Custom VPN Connections
Use HTTP Custom to create VPN-like tunnels for secure browsing.
3. Header Spoofing
Change headers to appear as a different device or browser.
4. Optimizing Mobile Data Usage
Modify requests to reduce bandwidth consumption or bypass throttling.
Conclusion
Creating an HTTP Custom (.hc) file allows for extensive customization of HTTP requests and responses, enabling users to bypass network restrictions, modify data, and use proxies effectively. By following best practices and ensuring your configurations are free of copyrighted content, you can leverage .hc files for various networking needs. Always test your configurations to ensure they function correctly and adhere to legal guidelines.
