How do I use ETag in my web application?
ETag, or Entity Tag, is a mechanism that web servers use to validate cached responses. You can use it to improve performance.
Can you explain how to implement ETag in my server?
Sure! You can generate an ETag by creating a hash of the resource's content and sending it in the response header.
What happens if the content changes?
If the content changes, you should generate a new ETag value. This way, clients can know when to fetch the updated resource.
Are there any downsides to using ETag?
One downside is that generating ETags can add overhead, especially for large resources. It's important to balance performance.
