About HTTP Status Checker
A page can look fine in a browser and still answer crawlers with an error, or hide a redirect along the way. Enter an address and our server sends it a HEAD request, which asks for headers only, follows up to 10 redirects, and reports the final status code with its name, the address it ended on, the redirect count and the total time in milliseconds. When more than one hop was involved, the chain is listed under the result.
Features
- Status code with its name, for example 404 Not Found
- Final URL after up to 10 redirects
- Response time for the whole request in milliseconds
- Hop-by-hop chain with a status code for each URL
- Refuses internal network and reserved addresses before any request is made
Limitations
- Public http and https addresses only. Localhost, internal network ranges, .local and .internal names, and hostnames that do not resolve are refused.
- The check uses a HEAD request and runs no JavaScript, so a server that treats HEAD differently from a normal page visit can report a different status.
- Redirect following stops after 10 hops, the server waits up to 10 seconds for a connection or a response, and each IP address is limited to 20 checks per minute.
- Only a fixed list of common status codes has a name here; others, such as 204 or 418, are labeled Unknown.
How it works
- Type or paste the address to check; if you leave out http:// or https://, https:// is added for you.
- Press Check Status and wait while our server requests the URL.
- Read the status badge: green for a 2xx code, amber for 3xx and red for anything else.
- Check the final URL, the response time and the number of redirects.
- If the address redirected, read the chain below the result for each hop and its code, then use Re-check or New URL.
Example input
https://example.com/old-pageFrequently asked questions
- Codes starting with 2 mean success, 3 a redirect, 4 a problem with the request such as 404 Not Found, and 5 a server error such as 503 Service Unavailable. The badge color follows the first digit: green, amber, then red for everything else.
- Only a fixed list of common codes, such as 200, 301, 404 and 503, has a built-in name. A valid code outside that list still appears as a number, but its description reads Unknown.
- The server follows redirects and reports where the last one landed. A move from http to https, an added www or a trailing slash is common. The redirect count and the chain show each hop, and the redirect checker lays them out step by step.
- When our server cannot connect you see a message instead: a timeout, a DNS failure for a domain that does not exist, a refused connection or an SSL certificate problem. Internal and reserved addresses are refused before any request is made.
- Yes. Unlike the browser-only tools on this site, the check has to be made by our server, so the address goes there and the server then requests it. The request identifies itself as AuraTools-SEO-Checker/1.0 and does not read robots.txt.
