The server responds with a three-digit\nHTTP status code\nthat indicates whether the request was successful or if something went wrong. These codes are grouped into categories and help explain the outcome of your request in a simple way.\nThis guide explains the\nmajor HTTP status code categories\nand highlights some of the\nmost common codes with their meanings, making it easy to understand what happens when you interact with a website.\nWhat are HTTP Status Codes?\nThe\nHTTP status code\nis a response made by the server to the client's request.\nThese are three-digit codes. There are over\n60 status codes\n, but they fall into five main categories:\n1xx -\nInformational Response (These status codes are all about the information received by the server when a request is made).\n2xx -\nSuccess (This status code depicts that the request made has been fulfilled by the server and the expected response has been achieved).\n3xx -\nRedirection (The requested URL is redirected elsewhere).\n4xx -\nClient Errors (This indicates that the page is not found).\n5xx -\nServer Errors (A request made by the client but the server fails to complete the request). \nMajor HTTP Status Codes\n1. 200  (Success\/OK)\nThe HTTP status code 200 represents success which means the page you have requested has been fetched. The action made has been accepted and has been delivered to the client by delivering the requested page. \nGET: entity in reference to the requested source sent to the response\nPOST: entity describing the response of action made\nHEAD: an entity-header field similar to the requested source \nTRACE: a request made by the client is taken care of by the server\n2. 301 (Permanent Redirect)\nThe HTTP status code 301 means that the page you have requested has moved to a new URL and which is permanent. In the future, whenever the user requests the same website, it will be redirected to the new URL.

Major changes in the URL will be in the future. Other than GET or HEAD, if the 302 is received in response to a request. The redirection is temporarily redirected to another website. \n4. 304 (Not Modified)\nHTTP status code 304 is used for caching purposes. The response has not been changed so that in the future the client can resume the same cache. If there's a GET request and access is allowed, but the document has not been modified. The response MUST NOT contain a message-body and therefore comes to an end by the first empty line. \n5. 400 (Bad Request)\nWhen the client requests a page and the server is not able to understand anything, it displays a 400 HTTP status code. The client SHOULD NOT repeat the request without any changes. The request can be a malformed, deceptive request routing, or invalid request.\nThis HTTP status code requires user authentication. The response includes the WWW-Authenticate header field containing a challenge applied to a requested source. HTTP access authentication \"HTTP Authentication: Basic and Digest Access Authentication\".\n7. 403 (Forbidden)\nThe HTTP status code 403 implies that the request is understood by the server, but still refuses to fulfill it. If the request method was not HEAD and also the server wants to make it public when the request is not completed, it SHOULD tell the reason for the refusal in the entity. \n8. 404 (Not Found)\n404 HTTP Status code appears when you request a URL and then the server has not found anything. This happens when the server doesn't wish to describe the reason why the request has been refused. Also, the server is not able to find a representation for the target resource. \n9. 500 (Internal Server Error)\n500 HTTP status code means requesting a URL is not fulfilled because the server encounters an unexpected condition.

Boilerpipe Text	Last Updated : 23 Jul, 2025 When you visit a website or make a request online, your browser communicates with a server using HTTP (Hypertext Transfer Protocol) . The server responds with a three-digit HTTP status code that indicates whether the request was successful or if something went wrong. These codes are grouped into categories and help explain the outcome of your request in a simple way. This guide explains the major HTTP status code categories and highlights some of the most common codes with their meanings, making it easy to understand what happens when you interact with a website. What are HTTP Status Codes? The HTTP status code is a response made by the server to the client's request. These are three-digit codes. There are over 60 status codes , but they fall into five main categories: 1xx - Informational Response (These status codes are all about the information received by the server when a request is made). 2xx - Success (This status code depicts that the request made has been fulfilled by the server and the expected response has been achieved). 3xx - Redirection (The requested URL is redirected elsewhere). 4xx - Client Errors (This indicates that the page is not found). 5xx - Server Errors (A request made by the client but the server fails to complete the request). Major HTTP Status Codes 1. 200 (Success/OK) The HTTP status code 200 represents success which means the page you have requested has been fetched. The action made has been accepted and has been delivered to the client by delivering the requested page. GET: entity in reference to the requested source sent to the response POST: entity describing the response of action made HEAD: an entity-header field similar to the requested source TRACE: a request made by the client is taken care of by the server 2. 301 (Permanent Redirect) The HTTP status code 301 means that the page you have requested has moved to a new URL and which is permanent. In the future, whenever the user requests the same website, it will be redirected to the new URL. The modified permanent URL is given by the location filed in response. 3. 302 (Temporary Redirect) The requested URL has been redirected to another website which is temporary. Major changes in the URL will be in the future. Other than GET or HEAD, if the 302 is received in response to a request. The redirection is temporarily redirected to another website. 4. 304 (Not Modified) HTTP status code 304 is used for caching purposes. The response has not been changed so that in the future the client can resume the same cache. If there's a GET request and access is allowed, but the document has not been modified. The response MUST NOT contain a message-body and therefore comes to an end by the first empty line. 5. 400 (Bad Request) When the client requests a page and the server is not able to understand anything, it displays a 400 HTTP status code. The client SHOULD NOT repeat the request without any changes. The request can be a malformed, deceptive request routing, or invalid request. This HTTP status code requires user authentication. The response includes the WWW-Authenticate header field containing a challenge applied to a requested source. HTTP access authentication "HTTP Authentication: Basic and Digest Access Authentication". 7. 403 (Forbidden) The HTTP status code 403 implies that the request is understood by the server, but still refuses to fulfill it. If the request method was not HEAD and also the server wants to make it public when the request is not completed, it SHOULD tell the reason for the refusal in the entity. 8. 404 (Not Found) 404 HTTP Status code appears when you request a URL and then the server has not found anything. This happens when the server doesn't wish to describe the reason why the request has been refused. Also, the server is not able to find a representation for the target resource. 9. 500 (Internal Server Error) 500 HTTP status code means requesting a URL is not fulfilled because the server encounters an unexpected condition. It gives information about the request made if it is successful, and throws an error. When there's an error during a connection to the server, and the requested page cannot be accessed then this message is displayed. 10. 501 (Not Implemented) When a request is made by the client, the server is not able to recognize the request method and is not able to support any resource. By default. it is cacheable. The methods, the server requires to support are GET and HEAD. The server does not support the functionality required to fulfill the request. Other HTTP Status Codes Are: 100 Continue 101 Switching Protocol 102 Processing (WebDAV) 103 Early Hints 200 OK 201 Created 202 Accepted 203 Non-Authoritative Information 204 No Content 205 Reset Content 206 Partial Content 207 Multi-Status (WebDAV) 208 Already Reported (WebDAV) 226 IM Used (HTTP Delta encoding) 300 Multiple Choice 301 Moved Permanently 302 Found 303 See Other 304 Not Modified 305 Use Proxy 306 Unused 307 Temporary Redirect 308 Permanent Redirect 400 Bad Request 401 Unauthorized 402 Payment Required 403 Forbidden 404 Not Found 405 Method Not Allowed 406 Not Acceptable 407 Proxy Authentication Required 408 Request Timeout 409 Conflict 410 Gone 411 Length Required 412 Precondition Failed 413 Payload Too Large 414 URI Too Long 415 Unsupported Media Type 416 Range Not Satisfiable 417 Expectation Failed 418 I'm a teapot 421 Misdirected Request 425 Too Early 426 Upgrade Required 428 Precondition Required 429 Too Many Requests 431 Request Header Fields Too Large 451 Unavailable For Legal Reasons 500 Internal Server Error 501 Not Implemented 502 Bad Gateway 503 Service Unavailable 504 Gateway Timeout 505 HTTP Version Not Supported 506 Variant Also Negotiates 507 Insufficient Storage (WebDAV) 508 Loop Detected (WebDAV) 510 Not Extended 511 Network Authentication Required Why HTTP Status Codes Matter Understanding HTTP status codes helps you figure out what’s happening when you interact with a website. Whether it’s a successful page load (200), a missing page (404), or a server issue (500), these codes provide clarity about the communication between your browser and the server. They’re especially useful for developers and website administrators to troubleshoot issues and improve user experiences. Conclusion HTTP status codes are like the internet’s way of talking to you about what’s happening behind the scenes. From confirming a successful request (2xx) to pointing out a missing page (404) or a server hiccup (500), these codes make it easier to understand and fix issues when browsing the web. By familiarizing yourself with these codes, you can better navigate errors, optimize websites, or simply know why a page didn’t load as expected.

Whether it’s a successful page load (200), a missing page (404), or a server issue (500), these codes provide clarity about the communication between your browser and the server. They’re especially useful for developers and website administrators to troubleshoot issues and improve user experiences. ## Conclusion HTTP status codes are like the internet’s way of talking to you about what’s happening behind the scenes. From confirming a successful request (2xx) to pointing out a missing page (404) or a server hiccup (500), these codes make it easier to understand and fix issues when browsing the web. By familiarizing yourself with these codes, you can better navigate errors, optimize websites, or simply know why a page didn’t load as expected. Whether you’re a casual user or a developer, knowing the basics of HTTP status codes** empowers you to interact with the digital world more confidently.
