To control the file cache time in the browser, you can use HTTP headers. Specifically, you can set the Cache-Control header with the max-age directive to specify how long the browser should cache a file. For example, setting "Cache-Control: max-age=3600" would tell the browser to cache the file for one hour.

Another header you can use is Expires, which specifies an exact date and time after which the file should no longer be considered fresh. This header takes a GMT format date, like "Expires: Thu, 01 Dec 2023 16:00:00 GMT".

Additionally, you can use the ETag header. The server generates a unique identifier for each file, and the browser sends this identifier back with subsequent requests. The server can then respond with a 304 Not Modified status if the file hasn't changed, telling the browser to use its cached version.

For example, in a web application deployed on Tencent Cloud, you can configure these headers through the Cloud Load Balancer or the Content Delivery Network (CDN) service, which allows fine-grained control over caching behavior to optimize performance and resource utilization.
