This resource can be cached.
This response can be cached because the server responded with an ETag header.
This resource does not have a cache control header.
Learn how to add the Cache-Control header to your responses.
This resource has an entity tag.
ETag: W/"160e72-64acfb3c8caec-gzip"
Since this response has an entity tag, the entity tag may be used to revalidate a response when it becomes stale. The first time the resource is requested by the client, the response will be cached along with the entity tag. On any subsequent requests, if the cached response is still fresh, then the cached response will be served.
However, if the cached response is stale, then on a subsequent request, the client may send the HTTP header
If-None-Match: W/"160e72-64acfb3c8caec-gzip"to see if the response has changed. If the response has not changed, the server will return a status code of
304 Not Modified to indicate the response is still fresh. Otherwise, if the response has changed, then the server will return the fresh, full response which can be cached again.etag: W/"160e72-64acfb3c8caec-gzip" last-modified: Sat, 14 Feb 2026 21:49:55 GMT vary: Content-Type,Accept-Encoding,User-Agent
The Last-Modified header indicates the last time the resource was modified on the origin server.
Last-Modified: Sat, 14 Feb 2026 21:49:55 GMT
In this case, the resource was last modified on Feb 14, 2026, 9:49:55 PM (less than a minute ago).
The Vary header indicates which request headers the server response may be dependent on. If any of the listed headers change, then the response may be different. This allows the server to send the correct cached response for each request. For example, ensuring that a client that does not support compression does not receive a cached compressed response.
Vary: Content-Type,Accept-Encoding,User-Agent
Accept-Encoding: The server response is expected to be different depending on the encodings that the client accepts via the Accept-Encoding header in the request. For example, if the client does not support compression, then the server may send a cached uncompressed response. If the client does support compression, for example, by sending a a Accept-Encoding: gzip header, then the server may send a cached compressed response.
User-Agent: The server response will depend on the user agent that the client sends in the request. Typically, this means that the server will cache responses for different browsers, operating systems, or devices.
