- Change from using `get_object` to `head_object` to check if the
sitemap file exists before attempting to retrieve it.
- Implement a presigned URL for accessing the sitemap, which is valid
for 15 minutes.
- Set cache headers to allow for 1 hour of caching.
- Improved logging for better error tracking and debugging.
This change enhances the efficiency of sitemap retrieval by reducing
unnecessary data transfer and provides a more secure way to access
the sitemaps through presigned URLs. It also improves error handling
by logging specific errors related to missing sitemaps.
