Does Python Requests Cache?

Yes, Python Requests module does cache responses by default to make subsequent requests faster and more efficient.

How Does Caching Work in Python Requests?

When a request is made, Python Requests checks if the response is already cached with the same URL and parameters. If yes, the cached response is returned instead of making a new request to the server. If no cache is found, Python Requests makes a new request and caches the response for future use.

What are the Advantages of Caching?

  • Caching can save time and resources by avoiding unnecessary requests to the server.
  • Caching can improve performance by reducing latency and network traffic.
  • Caching can help with offline usage by allowing previously fetched resources to be used even when a network connection is not available.

How to Disable Caching in Python Requests?

If caching is not desired for a particular request, it can be disabled using the cache_control parameter:

import requests

response = requests.get('', headers={'cache-control': 'no-cache'})

The above code sets the cache-control header to 'no-cache', which tells Python Requests not to use the cache for this request.

Caching can also be disabled globally for all requests by setting the max-age to zero:

import requests

requests_cache.install_cache('example_cache', expire_after=0)
response = requests.get('')

The above code sets the expire_after parameter to zero, which means that all cached responses will have expired immediately. As a result, Python Requests will not use the cache for any requests.
