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 about that error, and will error code 500 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 similar to the 401 error, but note the difference between un

is a list of Hypertext Transfer Protocol (HTTP) response status codes. It http 422 includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The first http 404 digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard wordings, http://royal.pingdom.com/2009/05/06/the-5-most-common-http-errors-according-to-google/ 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 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 https://en.wikipedia.org/wiki/List_of_HTTP_status_codes 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-contin
& 9 Most Common HTTP Errors Explained Published by Anna Monus,in Hosting Apart from the 404 error, how many other HTML error pages do you know about? Have you ever thought about what happens in the background when you see any of http://www.hongkiat.com/blog/common-http-errors/ these HTML error pages on your screen? Those codes are meant to convey important information to the user. It can be useful to know them better, especially if you are a website owner. Using them properly reduces your bounce http://stackoverflow.com/questions/37846014/throwing-bad-request-400-instead-of-internal-server-error-500 rate, improves your search engine ranking and gives you knowledge on the performance of your site. Understanding Status Codes Behind every error page you see on the web there is an HTTP status code sent by the web http status server. Status codes come in the format of 3 digit numbers. The first digit marks the class of the status code: 1XX status codes have informational purposes 2XX indicates success 3XX is for redirection None of these three classes result in an HTML error page as in this cases the client knows what to do and goes on with the task without hesitation. What we usually see are the 4XX and 5XX kind: 4XX represent client-side http status code errors 5XXs indicate problems on the server side HTML error pages are displayed in these cases because the client has no idea about what how to move on. Let’s see what happens in the background when something goes south and what you can do about it. Client-Side Errors (4XX) 1. 400 – Bad Request Whenever the client sends a request the server is unable to understand, the 400 Bad Request error page shows up. It usually happens when the data sent by the browser doesn’t respect the rules of the HTTP protocol, so the web server is clueless about how to process a request containing a malformed syntax. Pin itWhen you see a 400 error page the reason is most likely that there’s something unstable on the client side: a not sufficiently protected operating system, an instable internet connection, a defective browser or a caching problem. So it’s always a good idea to test a bit your own PC before you contact the owner of the website. Open the same webpage in a different browser, clear the cache, and check if you are due with security updates. If you regularly meet the 400 error on different sites, your PC or Mac is awaiting a thorough security checkup. 2. 401 – Authorization Required When there’s a password-protected web page behind the client’s request, the server responds with a
