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",
"cdn": {
"ttl": 604800,
"permanent": false
}
}
| Parameter | Type | Default | Range |
|---|
ttl | integer | 86400 | 60-2592000 |
permanent | boolean | false | - |
refreshInterval | integer | 0 | 0 or 21600-2592000 |
Permanent Captures
Store captures indefinitely for archival or permalinks.
{
"url": "https://example.com",
"cdn": {
"permanent": 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",
"cdn": {
"permanent": true,
"refreshInterval": 86400
}
}
- 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
}
}
