## What it is
requests-cache is a persistent HTTP caching library for Python's requests library, providing a drop-in CachedSession and optional global patching. It supports multiple storage backends including SQLite, Redis, MongoDB, DynamoDB, and file-based serialization, with flexible expiration via Cache-Control headers or custom schedules.

## Use cases
- cache http responses in python requests
- speed up web scraping with persistent caching
- avoid re-downloading api responses
- cache requests session to sqlite
- add ttl-based http caching to python scripts
- reduce api rate limit hits with response caching

## When to choose
- you already use the python requests library and want transparent caching
- you need persistent cached responses across script runs
- you want flexible expiration strategies and multiple storage backends

## When to avoid
- you use httpx or aiohttp instead of requests
- you need a standalone caching proxy rather than an in-process library
- you need distributed cache invalidation logic beyond HTTP semantics
