Server Response Codes
The formal name of these annoying Messages is Status Codes.
Here's a list of the most widely implemented Codes currently in use.
100-199 (silent)
SRCs provide confirmation that a Request was received and is being processed. |
| 100 | This is good. The Request was completed and the process can move along. |
| 101 | Request to switch protocols (like from HTTP to FTP) was accepted. |
200-299 (silent)
SRCs report that Requests were performed successfully. |
| 200 | It simply means all is okay. What the client Requested is available. |
| 201 | This means a new address was successfully created through a CGI or posting form data. |
| 202 | The client's Request was accepted, although not yet acted upon. |
| 203 | The accepted information in the entity Header is not from the original Server, but from a third party. |
| 204 | There is no Content in the Requested click. If you click on an image map section not attached to a Page. This allows the Server to just sit there waiting for another click rather than throwing an Error. |
| 205 | This allows the Server to reset the Content returned by a CGI. |
| 206 | Only partial Content is being returned for some reason. |
300-399 (usually silent)
Request was not performed, but a redirection is occurring. |
| 300 | The Requested address refers to more than one entity. Depending on how the Server is configured, you get an Error or a choice of which Page you want. |
| 301 | Page has been moved permanently, and the new URL is available. You should be sent there by the Server. |
| 302 | Page has been moved temporarily, and the new URL is available. You should be sent there by the Server. |
| 303 | This is a "see other" SRC. Data is somewhere else and the GET method is used to retrieve it. |
| 304 | This is a "Not Modified" SRC. If the Header in the Request asks "If Modified Since", this will return how long it's been since the Page was updated. |
| 305 | This tells the Server the Requested document must be accessed by using the proxy in the Location Header (i.e., ftp, http). |
| 307 | The requested URI has moved, but only temporarily. The Location header specifies the new location, but no information is given about the validity of the redirect inn the future. The client should use the revisit the original URI in the future. |
400-499
Request is incomplete for some reason. |
| 400 | There is a syntax Error in the Request. It is denied. |
| 401 | The Header in your Request did not contain the correct authorization Codes. You cannot see what you Requested. |
| 402 | Payment is required. It's not in use yet. |
| 403 | You are forbidden to see the document you Requested. It can also mean that the Server doesn't have the ability to show you what you want to see. |
| 404 | Document not found. The Page you want is not on the Server nor has it ever been on the Server. You may have misspelled the title or used an incorrect capitalization pattern in the URL. |
| 405 | The method you are using to access the File is not allowed. |
| 406 | The Page you are Requesting exists but you cannot see it because your own system doesn't understand the format the Page is configured for. |
| 407 | The Request must be authorized before it can take place. |
| 408 | The Request timed out. For some reason the Server took too much time processing your Request. Net congestion is the most likely reason. |
| 409 | Conflict. Too many people wanted the same File at the same time. Server overload. Try again. |
| 410 | The Page used to be there, but now it's gone. |
| 411 | Your Request is missing a Content-Length Header. |
| 412 | The Page you Requested has some sort of precondition set up. That means that if something is a certain way, you can have the Page. If you get a 412, that condition was not met. |
| 413 | Too big. What you Requested is just too big to process. |
| 414 | The URL you entered is too long. |
| 415 | The Page is an unsupported media type, like a proprietary File made specifically for a certain program. |
| 416 | The requested byte range is not available and is out of bounds. |
| 417 | The server is unable to meet the demands of the Except header given by the client. |
500-599
Error has occurred in the Server itself. |
| 500 | No associated user. |
| 501 | What you Requested of the Server cannot be done by the Server. |
| 502 | Your Server has received Error from the Server you are trying to reach. The "Bad Gateway" Error. |
| 503 | The format or service you are Requesting is temporarily unavailable. |
| 504 | The gateway has timed out. Similar to 408 Error except that the time-out occurred specifically at the gateway of the Server. |
| 505 | The HTTP protocol you are asking for is not supported. |
