Welcome to CacheControl’s documentation!¶
It was written because httplib2’s better support for caching is often mitigated by its lack of threadsafety. The same is true of requests in terms of caching.
$ pip install CacheControl
Some of the included cache storage classes have external requirements. See Storing Cache Data for more info.
For the impatient, here is how to get started using CacheControl
import requests from cachecontrol import CacheControl sess = requests.session() cached_sess = CacheControl(sess) response = cached_sess.get('http://google.com')
This uses a threadsafe in memory dictionary for storage.
The tests are all in cachecontrol/tests and is runnable by py.test.
CacheControl is relatively new and maybe have bugs. I have made an effort to faithfully port the tests from httplib2 to CacheControl, but there is a decent chance that I’ve missed something. Please file bugs if you find any issues!
With that in mind, CacheControl has been used sucessfully in a production environments, replacing httplib2’s usage.
If you give it a try, please let me know of any issues.
