Redirect Chain Test

Test your scraper's ability to follow HTTP redirect chains, detect circular loops, and handle meta refresh redirects.

Test Passing Criteria

How it works

Each chain starts at step 1 and redirects through multiple hops before reaching the final target. The target returns a JSON response with a secret verification key. For the circular loop, your scraper must detect the repeated URL and stop following redirects.

301 Permanent Redirect Chain

10 hops · Type: 301

Permanent

A chain of 10 permanent (301) redirects. Your scraper must follow each Location header until it reaches the final destination.

Start Chain/api/test/redirects/chain?step=1&max=10&type=301

302 Temporary Redirect Chain

10 hops · Type: 302

Temporary

A chain of 10 temporary (302) redirects. Similar to 301 but uses temporary redirect status codes. Some scrapers treat these differently.

Start Chain/api/test/redirects/chain?step=1&max=10&type=302

Circular Redirect Loop

3 hops · Type: LOOP

Loop

A 3-step circular redirect loop: step 1 redirects to step 2, step 2 to step 3, and step 3 back to step 1. Your scraper must detect the cycle and break out.

Start Chain/api/test/redirects/chain?step=1&max=3&type=loop

Meta Refresh Chain

5 hops · Type: META

HTML

A chain of 5 HTML pages using <meta http-equiv="refresh"> tags instead of HTTP redirect headers. Your scraper needs to parse HTML and follow the meta refresh URL.

Start Chain/api/test/redirects/chain?step=1&max=5&type=meta

Target Endpoint

All chains (except the loop) eventually redirect to the target endpoint, which returns a JSON response confirming completion:

GET /api/test/redirects/target?type=301

{
  "completed": true,
  "type": "301",
  "secret": "sm-redirect-completed-301",
  "message": "You successfully followed the redirect chain!"
}
