asks for a page that’s simply not available on your site. The reason for this is that there may be a link on your site that was wrong or the page might have been recently 404 error page examples removed from the site. As there is no web page to display, the web server 404 error page template sends a page that simply says "404 Page not found". The 404 error message is an HTTP (Hypertext Transfer Protocol) standard status 404 error fix code. This "Not Found" response code indicates that although the client could communicate to the server, the server could not find what was requested or it was configured not to fulfill the request. The 404 "Not Found" 404 error page html code error is not the same as the "Server Not Found" error which you see whenever a connection to the destination server could not be established at all. The default 404 error page as shown on Internet Explorer is given below. HTTP Status Code Whenever you visit a web page, your computer will request data from a server through HTTP. Even before the requested page is displayed in your browser, the web server will send

the HTTP header that has the status code. The status code provides information about the status of the request. A normal web page gets the status code as 200. But we do not see this as the server proceeds to send the contents of the page. It’s only when there is an error, we see the status code 404 Not Found. Origin of Status Codes As a part of the HTTP 0.9 specifications, the World Wide Web Consortium (W3C) established HTTP status codes in 1992. Tim Berners-Lee, who invented the web and the first web browser in 1990, defined the status codes. List of Status Codes A brief overview of HTTP status codes is given below. Code Meaning Description 100 Continue Confirms the client about the arrival of the first part of the request and informs to continue with the rest of the request or ignore if the request has been fulfilled 101 Switching Protocols Informs the client about the server switching the protocols to that specified in the Upgrade message header field during the current connection. 200 OK Standard response for successful requests 201 Created Request fulfilled and new resource created 202 Accepted Request accepted, but not yet processed 203 Non-Authoritative Information Returned meta information was not the definitive set from the origin server. 204 No Content Request succeeded wit

RSS ALL ARTICLES FEATURES ONLY TRIVIA Search How-To Geek 6 Types simple 404 page html of Browser Errors While Loading Web Pages and What They Mean You’re guaranteed to stumble into an occasional error page while browsing 404 error message text the web. This 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 http://www.404errorpages.com/ error or malware warning looks different in each different browser, but the different types of error pages mean the same thing. Certificate Error 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 http://www.howtogeek.com/133539/6-types-of-browser-errors-while-loading-web-pages-and-what-they-mean/ 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. However, it’s also possible that a website failed to properly renew or configure its certificate. Either way, you shouldn’t continue when you see this error message. Phishing and Malware Warnings Your browser will also display phishing (or “web forgery”) and malware warnings. Whether you use Firefox, Chrome, or Internet Explorer, your browser regularly downloads a list of dangerous websites. When you attempt to connect to a website on this list, you’ll see an error message. Websites are placed on these lists because they contain malware or because they attempt to impersonate a real website to steal your passwords,

In the development environment, Symfony catches all the exceptions and displays a special exception page with lots of debug information to help you quickly discover the root problem: Since these pages contain a lot of sensitive internal information, Symfony won't display them in the production environment. Instead, it'll show a simple and generic error page: Error pages for the production environment can be customized in different ways depending on your needs: If you just want to change the contents and styles of the error pages to match the rest of your application, override the default error templates; If you also want to tweak the logic used by Symfony to generate error pages, override the default exception controller; If you need total control of exception handling to execute your own logic use the kernel.exception event. Overriding the Default Error Templates¶ When the error page loads, an internal
