HTTP Status Code Checker

An HTTP Status Code Checker is an online tool that allows users to quickly determine the status code returned by a web server when accessing a specific URL. These tools send a request to the target webpage and display the HTTP response code along with additional diagnostic information.

Why HTTP Status Codes Matter

Every time a browser or application accesses a web resource, the server responds with a three-digit HTTP status code that indicates the success or failure of the request:

• 1xx (Informational): Temporary responses during connection

• 2xx (Success): Requests completed successfully (e.g., 200 OK)

• 3xx (Redirection): Further action needed to complete request

• 4xx (Client Errors): Problem with the request (e.g., 404 Not Found)

• 5xx (Server Errors): Server failed to fulfill valid request

Key Features of HTTP Status Code Checkers

1. Instant Verification: Quickly check if a website or page is returning the expected status

2. Redirect Tracing: Follow and display all redirects in a chain (301, 302, etc.)

3. Batch Processing: Some tools allow checking multiple URLs at once

4. Header Inspection: View full HTTP response headers

5. Response Time Measurement: Track how long the server takes to respond

Common Use Cases

• SEO Optimization: Ensure important pages return 200 status and fix 404 errors

• Website Migration: Verify proper redirects after moving content

• API Development: Test endpoint responses during development

• Troubleshooting: Diagnose website accessibility issues

• Monitoring: Regular checks for unexpected status changes

How to Use an HTTP Status Code Checker

1. Enter the URL you want to check

2. Select request method (GET, HEAD, POST, etc.)

3. Optionally set custom headers or user agents

4. Submit the request

5. Review the status code and additional response details

Advanced Functionality in Some Tools

• Historical Tracking: Monitor status code changes over time

• Scheduled Checks: Automate regular status verification

• Geolocated Testing: Check responses from different server locations

• API Access: Integrate status checking into automated workflows

Popular Online HTTP Status Checkers

Many free online tools provide this functionality, including:

• HTTPStatus.io

• Redirect Detective
