Find out what a web server responds with: the HTTP status code,
redirect chain, response headers and whether HTTPS is used.
Requests are made through clearly identified server-side services,
while browser timing is measured separately.
What this tool does
The HTTP Status Checker examines a public URL using
server-side services and reports the HTTP response information
returned by those services.
-
microLink follows the redirect chain and
reports the final status code, redirect hops and available
response headers.
-
hackertarget provides information about
the initial response, including the original status and
available
Location header.
Your browser also measures the time taken for the request
to reach the external service. This timing is labeled
separately as browser-measured information.
Why this is not a browser-only request
Browsers normally restrict JavaScript from reading responses
from other origins unless those servers explicitly allow it
through Cross-Origin Resource Sharing (CORS).
Instead of attempting to bypass this restriction, this tool
uses external services that perform the HTTP request from
their own servers.
Results are labeled according to their source, so you can
distinguish server-side information from browser-measured
timing.
Limitations & transparency
External API providers run their servers in specific
locations. Their connection to the target website may
differ from the connection made by a visitor in your country.
Results can therefore vary because of geographic routing,
caching, firewalls, CDNs, temporary server conditions,
network paths or rate limits.
If one external service is temporarily unavailable,
the tool displays an appropriate message rather than
presenting an invented result.
The checked URL is sent by your browser to the external
services used by this tool. YourAnalystAI has no backend
for storing these HTTP check results.

HTTP status codes — what they mean
- 200 OK
-
The server successfully processed the request and returned
a response.
- 301 Moved Permanently
-
A permanent redirect tells browsers and search engines
that a resource has moved to a new URL. When configured
correctly, search engines can consolidate signals toward
the destination URL.
- 302 Found
-
A 302 indicates a temporary redirect. The original URL
remains the requested address while the server directs
the visitor to another location for the current request.
- 307 Temporary Redirect
-
A temporary redirect that preserves the HTTP request method
when redirecting. This can matter for requests such as
POST submissions.
- 308 Permanent Redirect
-
A permanent redirect that preserves the HTTP request method
when redirecting. This can matter for requests such as
POST submissions.
- 404 Not Found
-
The requested resource could not be found at the specified
URL. Common causes include incorrect URLs, deleted pages
or missing redirects.
- 410 Gone
-
The server indicates that the requested resource is no
longer available and is intentionally gone.
- 500 Internal Server Error
-
The server encountered an unexpected condition while
processing the request.
- 502 Bad Gateway
-
A proxy or gateway received an invalid response from
an upstream server.
- 503 Service Unavailable
-
The server is temporarily unable to handle the request,
commonly because of maintenance, overload or temporary
service conditions.
Why HTTP status codes matter
HTTP status codes help explain how a web server handled
a request. They are useful when troubleshooting broken
pages, redirects, server errors and indexing problems.
For website owners, checking status codes can help identify
unnecessary redirects, missing pages, temporary outages
and configuration problems.
A status code should always be interpreted together with
the URL, redirect behavior, response headers and the context
in which the request was made.
Frequently Asked Questions
Why do the two APIs sometimes disagree?
They are separate servers making requests at different
moments. Caches, geographic routing, temporary server
changes or differences in the redirect chain can produce
different responses. The tool displays both sources so
you can compare them.
Are multiple redirects always a problem?
Not always. Redirects are often necessary when a URL has
moved or HTTP is being upgraded to HTTPS. However,
unnecessary or long redirect chains can add latency and
make troubleshooting and crawling more complicated.
Where possible, links should point directly to the final URL.
Does a 301 mean my HTTPS check failed?
A 301 redirect from HTTP to HTTPS is a common configuration
when a site permanently moves visitors to its HTTPS URL.
The tool reports the redirect and final URL so you can
inspect the complete chain.
Can you test a URL that requires a login?
No. The external services request the public page without
credentials. A protected URL will return whatever the
server makes available to anonymous visitors.
