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 involving file operations, requiring a long time to complete the request.

Understanding Status Codes Behind every error page you see on the web there is an HTTP status code sent by the web server. Status https://en.wikipedia.org/wiki/List_of_HTTP_status_codes 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 errors 5XXs indicate http://www.hongkiat.com/blog/common-http-errors/ 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 401 Authorization Required code. 401 doesn’t return

Errors on the Internet, error message and those annoying error messages, occur quite frequently — and can be quite frustrating — especially if you do not know the difference between a 404 error and a 502 error.

List of HTTP Response Codes: 400 Bad File Request Usually means the syntax used in the URL is incorrect (e.g., uppercase letter should be lowercase letter; wrong punctuation marks). 401 Unauthorized Server is looking for some encryption key from the client and is not getting it. Also, wrong password may have been entered. Try it again, paying close attention to case sensitivity. 403 Forbidden/Access Denied Similar to 401; special permission needed to access the site -- a password and/or username if it is a registration issue. Other times you may not have the proper permissions set up on the server or the site's administrator just doesn't want you to be able to access the site. 404 File Not Found Server cannot find the file you requested.

These network connections support sending response data from servers back to clients including the content of Web pages and also some protocol control information.Types of HTTP Error and Status CodesIncluded in the HTTP server response data for each request is a code number indicating the result of the request. These result codes are three-digit numbers divided into categories as follows:100-199 : informational status200-299 : success status300-399 : redirection status400-499 : client errors500-599 : server errorsOnly a few of the many possible error and status codes are commonly seen on the Internet or intranets. Codes related to errors are typically shown in the Web page displayed as output of a failed request, while other codes are not displayed to users. HTTP 200 "OK" The Web server processed the request successfully and transmitted content back to the browser. Most HTTP requests result in this status. Users rarely will see this code on the screen as Web browsers generally only show codes when there is some problem. HTTP Error 404 "Not Found" The Web server could not find the requested page, file, or other resource. HTTP 404 errors indicate the network connection between client and server was made successfully. This error most commonly occurs when users manually enter an incorrect URI into a browser or the Web server administrator removes a file without redirecting the address to a valid new location. Users must change their URL to fix this problem. HTTP Error 500
