How to Detect Bad Requests Many times bad requests are quite obvious, like when an image that is supposed to be there is not. Other times they are in the background where they are not immediately apparent.There are sometimes no visual indication of bad requests, so it is a good idea to always remove unused CSS and to be reasonably familiar with your pages and what resources they are using. Using a page speed tool to examine your pages is the best way to know if your file is calling non existent resources. Our Page Speed tool detects bad requests. How to fix Bad Requests Fixing bad requests is alot easier than finding them. If you find you have one or more, just remove the code that is calling the resource, or replace the missing resource. For example if your webpage is calling for an image, but the image isn't there, just change the image "src" so that it points to the image you want or remove the image entirely. by Patrick Sexton Sponsors Sponso

But now, let's take this call: GET api/companies/5/invoices/10 (get invoice 10 from company 5) Now, if company '5' doesn't exist, do we still return a 404 Not Found? Or should a 404 only be returned if the outer most resource can not be found (invoice 10, in this case).

But response body may contain anything. Full response will drive the next step. –Jangid Nov 17 '14 at 8:53 add a comment| 1 Answer 1 active oldest votes up vote 8 down vote accepted 404 is your best response. According the HTTP RFC, http://www.ietf.org/rfc/rfc2616.txt, a 400 Bad Request means: The request could not be understood by the server due to malformed syntax. Whereas, a 404 states: The server has not found anything matching the Request-URI. The entire URI is your resource identifier, and you're not finding a matching resource for that particular identifier. share|improve this answer answered Nov 17 '14 at 21:17 Josh Rack 79259 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to
Status codes 301 Moved Permanently 302 Found 303 See Other 403 Forbidden 404 Not Found 451 Unavailable For Legal Reasons v t e The 404 or Not Found error message is a Hypertext Transfer Protocol (HTTP) standard response code, in computer network communications, to indicate that the client was able to communicate with a given server, but the server could not find what was requested. The web site hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors encountered on the World Wide Web.

In the code 404, the first digit indicates a client error, such as a mistyped Uniform Resource Locator (URL). The following two digits indicate the specific error encountered. HTTP's use of three-digit codes is similar to the use of such codes in earlier protocols such as FTP and NNTP. At the HTTP level, a 404 response code is followed by a human-readable "reason phrase". The HTTP specification suggests the phrase "Not Found"[1] and many web servers by default issue an HTML page that includes both the 404 code and the "Not Found" phrase. A 404 error is often returned when pages have been moved or deleted. In the first case, it is better to employ URL mapping or URL redirection by returning a 301 Moved Permanently response, which can be configured in most server configuration
