Custom headers and cookies enable you to authenticate or add required headers for your web applications. You can add custom headers and cookies to sites, folders, or subfolders.

Adding custom headers

To add a custom header:

1. Select a site or folder, and then select the Details tab.
2. Under Scan settings, go to the Headers & cookies tab.
3. Click Add a header or cookie.
4. Select Add header.
5. Name - Enter the header name (for example: Connection or Authorization).
6. Value - Enter the header value. For example:
   • For Connection: keep-alive
   • For Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
   • For User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)
7. Scope Prefix - Enter https://api.example.com/ or leave empty for all requests.

Adding session cookies

To add a session cookie:

   • Name: session (the cookie name)

Understanding scope prefix

Scope prefix controls where your header or cookie is applied:

• With a prefix: Header/cookie only applies to URLs starting with that exact prefix
• Empty: Header/cookie applies to all requests within your site scope

Examples:

• https://example.com/admin/ - Only admin section
• https://api.example.com/v1/ - Only API v1 endpoints
• Empty - All requests in your site scope
