+### Cache example
+
+Flask-Compress can be integrated with caching mechanisms to serve compressed responses directly from the cache. This can significantly reduce server load and response times. Here is an example of how to configure Flask-Compress with caching using Flask-Caching. The example demonstrates how to create a simple cache instance with a 1-hour timeout, and use it to cache compressed responses for incoming requests.
+
+'''python
+# Initializing flask app
+app = Flask(__name__)
+cache = Cache(app, config={
+    'CACHE_TYPE': 'simple',
+    'CACHE_DEFAULT_TIMEOUT': 60*60  # 1 hour cache timeout
+})
+
+# Define a function to return cache key for incoming requests
+def get_cache_key(request):
+    return request.url
+
+# Initialize Flask-Compress
+compress = Compress()
+compress.init_app(app)
+
+# Set up cache for compressed responses
+compress.cache = cache
+compress.cache_key = get_cache_key
+'''
+
 ## Options
 
 Within your Flask application's settings you can provide the following settings to control the behavior of Flask-Compress. None of the settings are required.
