HTTP 302 Found indicates the resource temporarily resides at a different URL. The client should continue using the original URL for future requests. Despite being called 'Found,' it's actually a temporary redirect — the resource hasn't been found at the original URL, it's been found elsewhere temporarily. This is the most commonly used redirect in web applications, powering login redirects, A/B testing URL routing, and load balancing across origins.
Debug HTTP 302 live
Analyze real 302 behavior — headers, caching, CORS, redirects
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.

No common correctness warnings are specific to this code.
Guided Lab outcome
Reproduce HTTP 302 Found using a controlled endpoint and capture the full exchange.
Practice distinguishing status semantics from transport issues (redirects, caching, proxies).
Validate redirect correctness (Location, hop count, protocol safety) and SEO impact.
Technical deep dive
302 Found (RFC 7231 Section 6.4.3) was originally called 'Moved Temporarily.' Like 301, browsers historically change POST to GET when following 302, which is technically a violation of the spec. This behavior led to the creation of 307 (which preserves the method). In practice: use 302 for temporary redirects where method preservation doesn't matter, 307 when it does. SEO: Google treats 302 as temporary — it keeps indexing the original URL and doesn't transfer PageRank. If a 302 stays in place for months, Google may eventually treat it as a 301. Caching: 302 responses are NOT cacheable by default (unlike 301).
Real-world examples
Common 302 Found scenario 1
When a server returns 302 Found, it signals specific behavior that clients and intermediaries must handle correctly. For example, in web applications, this status is commonly encountered during URL routing, content negotiation, or resource management operations.
CDN and proxy behavior with 302
CDNs and reverse proxies handle 302 Found according to their configuration. The caching and forwarding behavior depends on whether the status is cacheable by default (per RFC 7231) and the presence of Cache-Control headers. Misconfigured intermediaries can cause redirect loops or cache stale redirects.
API design with 302 Found
In RESTful API design, 302 Found serves a specific semantic purpose. API gateways may intercept and modify these responses for versioning, rate limiting, or traffic management. Understanding when to use 302 versus similar status codes is critical for correct client behavior.
Framework behavior
Express.js (Node)
Express: res.redirect(302, 'https://new-url.com'). For 301/308 permanent: ensure the Location header is correct as browsers may cache it permanently.
Django / DRF (Python)
Django: return HttpResponseRedirect('/new-url/', status=302) or use the shortcut redirect() with permanent parameter for 301/308.
Spring Boot (Java)
Spring: return ResponseEntity.status(302).header("Location", "/new-url").build(). Spring's RedirectView can be configured with specific status codes.
FastAPI (Python)
FastAPI: return RedirectResponse(url='/new-url', status_code=302). For API redirects, ensure the client follows redirects with method preservation when using 307/308.
Debugging guide
Check the Location header value — typos or relative URLs in Location can cause redirect loops or 404s
Verify caching behavior: NOT cacheable by default — check Cache-Control headers
Test with curl -v -L to follow redirects and see the full chain
Check for redirect chains — each hop adds latency; aim for direct redirects
Monitor for method change (POST→GET) which is common with 302
When should I use 302 Found vs other redirect codes?
302 Found is temporary and may change the HTTP method. Choose based on permanence (will the redirect stay?) and method preservation (does POST need to stay POST?).
How do search engines handle 302 Found?
Search engines treat this as temporary and continue indexing the original URL. They do not transfer PageRank.
Is 302 Found cacheable?
No, 302 is NOT cacheable by default. Add Cache-Control: max-age=N if you want intermediaries to cache it.
What are common pitfalls with 302 Found?
Common issues include: redirect loops (A→B→A), missing Location header, relative vs absolute URLs in Location, unexpected method change from POST to GET, and excessive redirect chains that add latency.
Client expectation contract
Client can assume
A different URI is involved; Location may be required.
Client must NOT assume
Redirects will be followed automatically by all clients.
Retry behavior
Retries are generally unnecessary; treat as final unless domain rules require revalidation.
Monitoring classification
Redirect (policy-dependent)
Validate Location, caching headers, and chain behavior. Redirect loops/chains should alert.
