Caching & CDN

Optimize performance and reduce costs with caching and CDN storage.

Response Cache

Cache captures to avoid redundant processing for identical requests.

{
  "url": "https://example.com",
  "responseCache": {
    "enabled": true,
    "ttl": 86400
  }
}

Parameter	Type	Default	Range
`enabled`	boolean	`false`	-
`ttl`	integer	86400	60-2592000 (1min - 30 days)
`nonce`	string	-	max 32 chars

Cache Key

Caches are keyed by a hash of the full request parameters. Same URL with different options = different cache entry.

Cache Busting

Use nonce to force a fresh capture:

{
  "url": "https://example.com",
  "responseCache": {
    "enabled": true,
    "ttl": 86400,
    "nonce": "v2"
  }
}

CDN Storage

All captures are stored on our global CDN. Configure storage duration and auto-refresh.

{
  "url": "https://example.com",
  "cdnTtl": 604800,
  "persistence": {
    "enabled": false
  }
}

Parameter	Type	Default	Range
`cdnTtl`	integer	86400	60-2592000
`persistence.enabled`	boolean	`false`	-
`persistence.refreshInterval`	integer	0	0 or 21600-2592000

Permanent Captures

Store captures indefinitely for archival or permalinks.

{
  "url": "https://example.com",
  "persistence": {
    "enabled": true
  }
}

Permanent captures are accessible via the Permalinks section in your dashboard.

Auto-Refresh

Automatically refresh captures at set intervals (minimum 6 hours).

{
  "url": "https://example.com",
  "persistence": {
    "enabled": true,
    "refreshInterval": 86400
  }
}

This is useful for:

Monitoring pages for changes
Keeping cached thumbnails up-to-date
Scheduled archiving

Cache Response Indicator

The response includes fromCache to indicate cache status:

{
  "success": true,
  "data": {
    "fileUrl": "https://cdn.snapopa.com/...",
    "fromCache": true
  }
}
