Working Around Key Length Errors

If you see errors about key length (such as "MemcachedKeyLengthError: Key length is > 250"), you can ask DjangoCache to hash the keys it uses by specifying a key_hash_algorithm:

long_url = 'https://www.glassesdirect.co.uk/?q=' + ('x' * 250)
session = CacheControl(
    requests.session(),
    cache=DjangoCache(key_hash_algorithm='sha512')
)
session.get(long_url)

Note that when hashing these keys, there is a very small chance of a hash collision causing a request for one URL to return the content of another.
