sudo pip install flask_cache

from flask import Flask
from flask.ext.cache import Cache

cache = Cache()

config = {
  'CACHE_TYPE': 'redis',
  'CACHE_REDIS_HOST': '127.0.0.1',
  'CACHE_REDIS_PORT': 6379,
  'CACHE_REDIS_DB': '',
  'CACHE_REDIS_PASSWORD': ''
}

app = Flask(__name__)
app.config.from_object(config)
cache.init_app(app)

@app.route('/')
@cache.cached(timeout=60*2)
def index():
  name = 'mink'
  return name

if __name__ == '__main__':
  app.run()
