Should I use Max age or expires?
Quick Answer: Expires sets an expiry date for when a cookie gets deleted. Max-age sets the time in seconds for when a cookie will be deleted (use this, it’s no longer 2009)
What is Cors max age?
The default value is 5 seconds. In the present case, the max age is 86400 seconds (= 24 hours).
What is Max age in Cache-Control?
Cache-control: max-age
It is the maximum amount of time specified in the number of seconds. For example, max-age=90 means that a HTTP response remains in the browser as a cached copy for the next 90 seconds before it can be available for reuse.
How do I change my Cache-Control max age?
Cache-Control: max-age=<seconds>
This directive tells the browser or intermediary cache how long the response can be used from the time it was requested. A max-age of 3600 means the response can be used for the next 60 minutes before it needs to fetch a new response from the origin server.
When should you not use cache?
7 Reasons Not to Put a Cache in Front of Your Database
- How are most cache deployments implemented?
- An external cache adds latency.
- An external cache is an additional cost.

What problems do cache cause?
Caching as a solution to the performance/latency/throughput problems means there is more complexity, which will lead to more bugs. Bugs with caches can be subtle and difficult to debug, and bugs with caches can also cause live site outages.
Why cache is faster than RAM?
CPU cache is built into the CPU or on an adjacent chip. Its memory access time reportedly is 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to the CPU request. RAM data access is faster than read-only memory and mechanical storage devices, such as hard disks and tape.
What happens if you don’t accept cookies?
What happens if you don’t accept cookies? – The potential problem with refusing to accept cookies is that some website owners may not allow you to use their websites if you don’t accept their cookies.

Is SSD faster than RAM?
First, the memory chips in SSDs are slower than those in RAM. Second, there is a bottleneck created by the interface that connects the storage device to the computer. RAM, in comparison, has a much faster interface.
What happens if we remove cache memory?
Tip: Clearing the cache simply clears temporary files. It won’t erase login credentials, downloaded files, or custom settings.
Can cookies steal passwords?
Like a phishing attack, cookie hijacking allows a cybercriminal to steal personal information like usernames, passwords, and other important data held within the cookie.
