What types of headers have you used in your projects?

In QA and test automation projects, the following types of headers are often used:

• HTTP headers — for configuring requests and responses, e.g., Content-Type, Authorization, Accept.
• Authentication headers — for example, Bearer Token in Authorization for API access.
• Custom headers — specific to the project, e.g., X-Request-ID for request tracing.
• Caching headers — Cache-Control, ETag for cache management.

Example of using HTTP headers in an automated test in Python with requests:

import requests

headers = {
    'Authorization': 'Bearer your_token',
    'Content-Type': 'application/json',
    'Accept': 'application/json'
}
response = requests.get('https://api.example.com/data', headers=headers)
print(response.status_code)
