The first digit of the status code specifies one of five classes of response; an HTTP client must http code 302 recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The 500 error code Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions.[4] 100 Continue The server has received the request headers and the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body. The response 417 Expectation Failed indicates the request should not be continued.[2] 101 Switching Protocols The requester has asked the server to switch protocols and the server has agreed to do so.[5] 102 Processing (WebDAV; RFC 2518) A WebDAV request may contain many sub-requests

6, 2009 in Tech blog Sometimes when you try to visit web page, you’re met with an HTTP error message. It’s a message from the web server that something went http://royal.pingdom.com/2009/05/06/the-5-most-common-http-errors-according-to-google/ wrong. In some cases it could be a mistake you made, but often http://www.iana.org/assignments/http-status-codes it’s the site’s fault. Each type of error has an HTTP error code dedicated to it. For example, if you try to access a non-existing page on a website, you will be met by the familiar 404 error. Now, you might wonder, which are the most common HTTP errors that people encounter http status when they surf the Web? That is the question we’ll answer in this article. Google to the rescue Why not let millions of Web users tell us themselves what errors they encounter the most? In an indirect way we can do that via Google. The basic idea here is that some of the people who encounter errors when they visit websites will want to know more http status code about that error, and will go to the nearest search engine to do so. In short, Google’s search statistics should in this case be able to give us a pretty good idea of which HTTP errors are most common. Using Google Insights for Search (a great tool for estimating the “popularity” of search terms) we went through all of the different HTTP error codes that exist, comparing them against each other. When the dust settled from this little shootout, we had the top list you can see here below. The top 5 errors, according to Google Here they are, listed and explained in reverse order, the five most common HTTP errors. Drumroll, please… 5. HTTP error 401 (unauthorized) This error happens when a website visitor tries to access a restricted web page but isn’t authorized to do so, usually because of a failed login attempt. 4. HTTP error 400 (bad request) This is basically an error message from the web server telling you that the application you are using (e.g. your web browser) accessed it incorrectly or that the request was somehow corrupted on the way. 3. HTTP error 403 (forbidden) This error is
