To set a connection timeout in Flask Redis cache, you can use the connect_timeout parameter when initializing the Redis cache. Here's an example of how you can set the connection timeout to 5 seconds:

 1

 5

 8
 9
10

from flask import Flask
from flask_caching import Cache
import redis

app = Flask(__name)
cache = Cache(app, config={'CACHE_TYPE': 'redis', 'CACHE_REDIS_URL': 'redis://localhost:6379/0', 'CACHE_REDIS_CONNECT_TIMEOUT': 5})

@app.route('/')
@cache.cached(timeout=60)
def index():
    return "Hello World!"

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

In the above code snippet, we are initializing the Flask cache with a Redis cache using the CACHE_REDIS_URL parameter. We also specify the CACHE_REDIS_CONNECT_TIMEOUT parameter to set the connection timeout to 5 seconds.

By setting the CACHE_REDIS_CONNECT_TIMEOUT parameter, you can control how long the cache should wait for a connection to be established with the Redis server before timing out. Adjust the value according to your needs to set a suitable connection timeout for your application.
