Cookie Playground - Subdomain C

Welcome to subdomain C. This site allows you to test cookie behavior during redirects.

Available Pages

• Set Cookie - Configure and set cookies with various attributes (HTML form)
• Redirect to A - Navigate to a page that redirects to site A
• Pixel Redirect - Test redirect via pixel/image (non-top-level navigation)

HTTP Cookie Setting Endpoint

The /set-cookie path can also be used as an HTTP endpoint to set cookies via Set-Cookie headers:

• With query parameters: Sets cookie via HTTP response header
  • /set-cookie?name=test&value=123 - Basic cookie
  • /set-cookie?name=test&value=123&domain=site-c.cookie-playground.pun7o.click&path=/ - With domain and path
  • /set-cookie?name=test&value=123&httpOnly=true&secure=true&sameSite=Lax - With flags
• Without query parameters: Serves HTML form page

Query Parameters: name (required), value (required), domain, path, maxAge, expires, httpOnly (true/false), secure (true/false), sameSite (Strict/Lax/None)

Redirect Paths

Paths starting with /redirect or /go will automatically redirect to site A:

• /redirect - Redirects to site A root (301 - Permanent)
• /redirect/test - Redirects to site A /test (301 - Permanent)
• /redirect?status=301 - Explicit 301 (Permanent) redirect
• /redirect?status=302 - 302 (Temporary) redirect
• /go - Redirects to site A root (301 - Permanent)

Note: Use ?status=302 query parameter for temporary redirects, or ?status=301 for permanent redirects. Default is 301.
