- Capture and apply session: reuse existing web browser sessions with tools like curl. This feature captures cookies and headers from browser traffic and applies them to matching requests. Here is a sample rule you can import to reuse any captured browser session in curl requests:
rules:
- filter:
typeKind: AnyFilter
actions:
- typeKind: CaptureSessionAction
captureCookies: true
captureRequestCookies: true
captureHeaders:
- Authorization
- X-CSRF-Token
- X-Auth-Token
- filter:
typeKind: RequestHeaderFilter
headerName: User-Agent
pattern: curl
operation: Contains
actions:
- typeKind: ApplySessionAction
applyCookies: true
applyHeaders: true
mergeWithExisting: true
Rule importation can be accessed by typing "manage rules" in the search box (or menu > Settings > Manage rules). A blog article illustrating this feature is available at /resources/blogs/share-and-reuse-browser-session.
