The ETag header is used for web cache validation and helps in managing conditional requests.
How does the ETag header improve performance?
It allows browsers to cache resources and only request them again if they have changed, reducing bandwidth.
Can you explain how to implement ETag headers in a web server?
Sure! You can implement ETags by generating a unique identifier for each resource and sending it in the ETag header.
What happens if the ETag value changes?
If the ETag value changes, the client will know that the resource has been modified and will fetch the new version.
