Expire URL Cache

What is the "Photo URL Cache Expiration" setting?

The "Photo URL Cache Expiration" setting determines the duration for which the share links (URLs) of uploaded photos are saved in the cache. This cached URL is used to quickly access the photo's link without needing to re-upload the photo each time you need the link.

How does this setting benefit me?

1. Time-Saving: When you want to generate a QR Code or send the photo link via text to a mobile device, the cached URL allows for immediate access without the need to re-upload the photo.
2. Efficiency: Reduces the workload on your network and photo hosting service (e.g., Google Drive, Dropbox) by minimizing repeated uploads of the same photo.

How do I configure the Photo URL Cache Expiration setting?

1. Navigate to the Advanced Settings section in your application's settings menu.
2. Under the General tab, locate the Photo URL Cache Expiration option.
3. Set the number of days you want the URL to remain in the cache.
4. Click the Clear Cache button if you need to manually clear the cached URLs.

What happens when the cache expires?

When the cache expires, the saved URL is deleted. The next time you request the link for the same photo (to generate a QR Code or send it via text), the photo will need to be re-uploaded to the service to generate a new URL.

Can I manually clear the cache before it expires?

Yes, you can manually clear the cache by clicking the Clear Cache button. This will remove all saved URLs, forcing new uploads and link generation for subsequent photo access requests.

How do I know what the current cache duration is?

The current cache duration is displayed in the Photo URL Cache Expiration setting in the number of days you have configured.

Is there a default expiration period?

The default expiration period is typically set by the application. Check the setting for the pre-configured number of days. You can adjust this according to your needs.

What should I set as the expiration period?

The optimal expiration period depends on your usage pattern: - If you frequently access the same photos within a short timeframe, a longer cache duration is beneficial. - If you rarely reuse photo URLs or want to ensure the latest uploads are always used, a shorter cache duration is more suitable.

Important Note

The URL is retrieved based on the file path. If you reuse the same file path for different photos, it will return the previous URL associated with that file path from the cache. To ensure a new URL is generated for the new photo, you should clear the cache before uploading the new photo.

By understanding and configuring the Photo URL Cache Expiration setting, you can optimize your workflow for better efficiency and time management.
