Error codes
100-199 : Informational status
200-299 : Success status
300-399 : Redirection status
400-499 : Client errors
500-599 : Server errors
400 – Bad Request – You probably typed in a URL wrong, the server has no clue what you’re looking for, or you aren’t allowed to have access. Usually, it’s a matter of the URL being typing in wrong. Maybe you mixed upper and lowercase letters or something.
401 – Unauthorized Request – you tried to get to something on the web server you’re not allowed to play with. In other words, you ain’t on the party list.
403 – Forbidden – You can’t access the page. You may not have access (it may require a password), or it may be blocked from your domain.
404 – Not Found – The page you were trying to look at was not found on the server. This is probably the most common error you’ll come across. What has probably happened is that the web page you were going to has been removed or re-named.
500 – Internal error – Usually caused by a CGI error. You fill out a form, but the script used to process it is not working properly.
503 – Service Unavailable – The server may be overloaded, down, or have other similar problems. Try later.

101 Switching Protocols
200 OK The request was successful
The 200 status code is by far the most common returned. It means, simply, that the request was received and understood and is being processed.

201 Created The request was successful and a new resource was created (for example a new page).
202 Accepted The request was accepted for processing, but the processing is not yet complete.
The status code 202 indicates that server has received and understood the request, and that it has been accepted for processing, although it may not be processed immediately.

203 Non-Authoritative Information.
A 203 status code means that the request was received and understood, and that information sent back about the response is from a third party, rather than the original server. This is virtually identical in meaning to a 200 status code.

204 No Content The server has processed the request but there is no new information to be returned
205 Reset Content The 205 status code is a request from the server to the client to reset the document from which the original request was sent. For example, if a user fills out a form, and submits it, a status code of 205 means the server is asking the browser to clear the form.
206 Partial Content
A status code of 206 is a response to a request for part of a document. This is used by advanced caching tools, when a user agent requests only a small part of a page, and just that section is returned.

300 Multiple Choices The requested resource is available at one or more locations
The 300 status code indicates that a resource has moved. The response will also include a list of locations from which the user agent can select the most appropriate.

301 Moved Permanently The requested resource has been assigned a new URL and any further references should use this new URL
A status code of 301 tells a client that the resource they asked for has permanently moved to a new location. The response should also include this location. It tells the client to use the new URL the next time it wants to fetch the same resource.

302 Moved Temporarily/Found The requested resource resides at a different location, but will return to this location in the future
A status code of 302 tells a client that the resource they asked for has temporarily moved to a new location. The response should also include this location. It tells the client that it should carry on using the same URL to access this resource.

303 See Other
A 303 status code indicates that the response to the request can be found at the specified URL, and should be retrieved from there. It does not mean that something has moved - it is simply specifying the address at which the response to the request can be found.

304 Not Modified The requested resource has not been modified since the date specified in the If-Modified_Since header
The 304 status code is sent in response to a request (for a document) that asked for the document only if it was newer than the one the client already had. Normally, when a document is cached, the date it was cached is stored. The next time the document is viewed, the client asks the server if the document has changed. If not, the client just reloads the document from the cache.

307 - Temporary Redirect
307 is the status code that is sent when a document is temporarily available at a different URL, which is also returned. There is very little difference between a 302 status code and a 307 status code. 307 was created as another, less ambiguous, version of the 302 status code.
400 Bad Request The server could not properly interpret the request. Normally means that either address hasn’t been entered correctly or the page no longer exists.
A status code of 400 indicates that the server did not understand the request due to bad syntax.

401 Unauthorized The site being accessed is protected and you either entered the incorrect password or the host does not want users coming from your domain to enter.
A 401 status code indicates that before a resource can be accessed, the client must be authorised by the server.

402 Payment Required
The 402 status code is not currently in use, being listed as "reserved for future use".

403 Forbidden You are not permitted to access this document. It is either password-protected or the host does not want your domain to enter.
A 403 status code indicates that the client cannot access the requested resource. That might mean that the wrong username and password were sent in the request, or that the permissions on the server do not allow what was being asked.

404 Not Found The host server can’t find the HTML document at the URL you’ve entered. Either you have mistyped the URL, the document no longer exists, or you’ve been given the wrong URL.
The best known of them all, the 404 status code indicates that the requested resource was not found at the URL given, and the server has no idea how long for.

405 Method Not Allowed

406 Not Acceptable
The 406 status code means that, although the server understood and processed the request, the response is of a form the client cannot understand. A client sends, as part of a request, headers indicating what types of data it can use, and a 406 error is returned when the response is of a type not in that list.

407 Proxy Authentication Required
The 407 status code is very similar to the 401 status code, and means that the client must be authorized by the proxy before the request can proceed.

408 Request Time-Out
A 408 status code means that the client did not produce a request quickly enough. A server is set to only wait a certain amount of time for responses from clients, and a 408 status code indicates that time has passed.

409 Conflict
A 409 status code indicates that the server was unable to complete the request, often because a file would need to be edited, created or deleted, and that file cannot be edited, created or deleted.

410 Gone
A 410 status code is the 404's lesser known cousin. It indicates that a resource has permanently gone (a 404 status code gives no indication if a resource has gine permanently or temporarily), and no new address is known for it.

413 Request Entity Too Large
The 413 status code indicates that the request was larger than the server is able to handle, either due to physical constraints or to settings. Usually, this occurs when a file is sent using the POST method from a form, and the file is larger than the maximum size allowed in the server settings.

416 - Requested Range Not Satisfiable

417 - Expectation Failed
The 417 status code means that the server was unable to properly complete the request. One of the headers sent to the server, the "Expect" header, indicated an expectation the server could not meet.
500 Internal Server Error The server could not satisfy the request due to an internal error condition.
