Geek 6 Types of Browser Errors While Loading Web Pages and What They Mean You’re guaranteed to stumble into an occasional error page while browsing the web. This http://www.hongkiat.com/blog/common-http-errors/ guide will help you understand exactly what each error page means and what to do when you see them. Note that each browser displays and words its error pages differently. A certificate error or malware warning looks different in each different browser, but the different types of error pages mean the same thing. Certificate Error http://www.howtogeek.com/133539/6-types-of-browser-errors-while-loading-web-pages-and-what-they-mean/ An SSL certificate error or security certificate error indicates a problem with HTTPS encryption. You’ll only see this error when connecting to a website using HTTPS. When using HTTPS encryption, websites present certificates to identify that they are legitimate. For example, Google.com has a security certificate issued by a trusted certificate authority. The certificate authority verifies that Google is the real owner of Google.com and is entitled to the certificate. When you connect to Google.com using HTTPS, Google presents this certificate. Your browser checks that the certificate was issued by a known legitimate certificate authority to verify you’re connecting to the real Google.com, not another server pretending to be Google.com. When you see a certificate error, this indicates that you’re not necessarily connecting to the real, legitimate website. For example, if you try to access your bank’s website on a public Wi-Fi network and see this error, it’s possible that the network is compromised and someone is attempting to impersonate your bank’s website

It https://en.wikipedia.org/wiki/List_of_HTTP_status_codes includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these https://shiftwebsolutions.com/15-common-web-errors/ 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 Internet Assigned error message 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 involving file operations, requiring a long time to co

It is a general-purpose error, and can occur any time a web server encounters an internal problem. Error 500 happens most often when a web server is overloaded. 401 Unauthorized Web users will likely stumble across this error after a failed login attempt. Basically, it means the user tried to access a site they didn't have access to. 400 Bad Request This error message will appear when something has gone wrong with your web browser. It means that your request was corrupted in some way. 403 Forbidden When there is no login opportunity on a page, you will get a 403 error on a page if you try to access a forbidden directory on a website. 404 Not Found When a user tries to access a web page that doesn't exist, they will get a 404 error. This is usually the result of a broken link, a web page that has been moved, the user mistyped the URL, or the page was simply deleted. 408 Request Timeout A 408 error occurs when the user stops the request before the server finished retrieving information. This error will appear when a user closes the browser, clicks on a link too soon, or hits the stop button. It is also common to see this error when a server is running slow, or a file is very large. 501 Not Implemented When this error appears, it means the user has requested a feature that the browser does not support. 502 Service Temporarily Overloaded A 502 error occurs when there is server congestion. Usually this error corrects itself, when web traffic decreases. 503 Service Unavailable If the site is busy, or the server is down, users may get a 503 error. Connection Refused by Host This error is very similar to the 403 error. It means the user either doesn't have permission to access the site, or an entered password is not correct. File Contains No Data When a page is there, but nothing shows up, users can see a file contains no data error. This error is probably caused by stripped header information or bad table formatting. Cannot Add Form Submission Result to Bookmark List Only a document or a web address can be saved as a bookmark. If a user tries to save any other type of form, they will get this error. Helper Application Not Found If a user tries to download a file that requir
