    About This Tool

    This page provides original, human-reviewed information about HTTP connection testing, explaining status codes, redirect chains, and latency measurements so you can interpret results correctly.

    About HTTP/HTTPS Testing

    What is HTTP/HTTPS Testing?

    HTTP/HTTPS testing is a comprehensive analysis of web server responses, performance metrics, and security configurations. It helps identify connectivity issues, performance bottlenecks, and security vulnerabilities.

    How it Works

    Our HTTP testing tool performs the following checks:

    • Connectivity Test:Verifies if the server is reachable and responding
    • Performance Analysis:Measures DNS lookup, TCP connection, SSL handshake, and response times
    • Security Assessment:Checks for HTTPS usage, security headers, and SSL certificate validity
    • Response Analysis:Examines HTTP status codes, headers, and redirects

    Supported Methods

    The tool supports various HTTP methods including GET, POST, PUT, DELETE, HEAD, and OPTIONS. Each method serves different purposes in web communication.

    Performance Metrics

    We measure several key performance indicators:

    • DNS Lookup:Time to resolve domain name to IP address
    • TCP Connect:Time to establish TCP connection
    • SSL Handshake:Time for SSL/TLS negotiation (HTTPS only)
    • Server Processing:Time for server to process the request
    • Content Transfer:Time to download the response

    Security Analysis

    Our security analysis includes:

    • SSL certificate validation and details
    • Security headers presence and configuration
    • HTTPS redirect and HSTS implementation
    • Common security vulnerabilities detection
    Parameters Guide

    URL Parameter

    Enter the URL you want to test. You can provide:

    • Domain only:example.com (will default to HTTPS)
    • Full URL:https://example.com or http://example.com
    • With path:https://example.com/api/endpoint
    • With port:https://example.com:8443

    HTTP Methods

    GET

    Retrieves data from the server. Most common method for web pages and APIs.

    POST

    Sends data to the server. Used for form submissions and API data creation.

    PUT

    Updates or creates resources on the server. Idempotent operation.

    DELETE

    Removes resources from the server. Used for data deletion.

    HEAD

    Similar to GET but returns only headers, no body content.

    OPTIONS

    Returns allowed methods and CORS information for the resource.

    Performance Thresholds

    Our tool uses the following performance thresholds:

    • DNS Lookup:Good ≤ 50ms, Fair ≤ 100ms
    • TCP Connect:Good ≤ 100ms, Fair ≤ 200ms
    • SSL Handshake:Good ≤ 200ms, Fair ≤ 400ms
    • Server Processing:Good ≤ 200ms, Fair ≤ 500ms
    • Content Transfer:Good ≤ 100ms, Fair ≤ 300ms
    • Total Time:Good ≤ 500ms, Fair ≤ 1000ms
    HTTP Status Codes

    1xx Informational

    CodeStatusDescription
    100ContinueServer received request headers, client should send body
    101Switching ProtocolsServer is switching protocols as requested

    2xx Success

    CodeStatusDescription
    200OKRequest successful, response contains requested data
    201CreatedRequest successful, new resource created
    204No ContentRequest successful, no content to return

    3xx Redirection

    CodeStatusDescription
    301Moved PermanentlyResource permanently moved to new URL
    302FoundResource temporarily moved to different URL
    304Not ModifiedResource not modified since last request

    4xx Client Error

    CodeStatusDescription
    400Bad RequestServer cannot process request due to client error
    401UnauthorizedAuthentication required
    403ForbiddenServer understood request but refuses to authorize
    404Not FoundRequested resource not found
    429Too Many RequestsRate limit exceeded

    5xx Server Error

    CodeStatusDescription
    500Internal Server ErrorGeneric server error
    502Bad GatewayInvalid response from upstream server
    503Service UnavailableServer temporarily unavailable
    504Gateway TimeoutUpstream server timeout
    httptest.troubleTitle

    Connection Issues

    DNS Resolution Failed

    Cause:Domain name cannot be resolved to IP address
    Solution:Check domain spelling, verify DNS settings, try different DNS server

    Connection Timeout

    Cause:Server not responding or network issues
    Solution:Check server status, verify firewall settings, try different network

    SSL/TLS Issues

    Certificate Expired

    Cause:SSL certificate has expired
    Solution:Contact website administrator to renew certificate

    Certificate Mismatch

    Cause:Certificate issued for different domain
    Solution:Verify URL is correct, check certificate details

    Performance Issues

    Slow DNS Lookup

    Cause:DNS server responding slowly
    Solution:Use faster DNS servers (8.8.8.8, 1.1.1.1), check local DNS cache

    High Response Time

    Cause:Server overloaded or network congestion
    Solution:Try different time, check server status, optimize requests

    Security Warnings

    Missing Security Headers

    Impact:Increased vulnerability to attacks
    Recommendation:Implement proper security headers (CSP, HSTS, X-Frame-Options)

    HTTP Instead of HTTPS

    Risk:Data transmitted in plain text
    Solution:Enable HTTPS, implement HTTP to HTTPS redirects
