httpcache: Caching for Python Requests¶
Love Requests? Wish it had HTTP caching? Well then, this is the project for you.
Built from the ground up for combining with your favourite HTTP library, this library provides totally transparent HTTP caching. Fully RFC 2616-compliant, no muss, no fuss. Just plug in and go.
>>> import requests >>> from httpcache import CachingHTTPAdapter >>> s = requests.Session() >>> s.mount('http://', CachingHTTPAdapter()) >>> s.mount('https://', CachingHTTPAdapter())
Any request passed through that session will automatically use the HTTP cache. Guess what? Requests just got better.
If this library doesn’t float your boat, you can also take a look at the excellent CacheControl library, which directly ports httplib2’s caching algorithms.
httpcache fully supports HTTP/1.1 caching, and ties deep into Requests. That means:
- Supports Expires headers.
- Supports Cache-Control headers.
- Understands 304 Not Modified responses.
- Can do validation caching, i.e. If-Modified-Since headers.
- Correctly navigates the waters of HTTP verbs and urls.
- Fully supports RFC 2616.
Caching with Requests should be as easy as HTTP with Requests. Stop worrying about it. Just benefit from it.
httpcache supports all the versions of Python that Requests supports. We intend to do this indefinitely. Currently, this means we support 2.6, 2.7 and 3.3. It is possible that httpcache functions on earlier versions of Python, but such functionality is not supported and may be broken in any version change.
