Permanent Relocation - The requested resource has been permanently moved to a new URL. Usually accompanied by Location: newURL which automatically connects to the new URL.

301

Moved Target - The page you were attempting to reach has been moved. This move is Most likely to be permanent, but it is possible that this is only a temporary move.

302

Moved temporarily/Redirect - You will get this error if someone has moved the target page for only a short amount of time. You will be forwarded to the correct URL as this relocation is only temporary. Requested resource found, but at a different URL. You’ll get a 302 Redirection if you omit the trailing slash when pointing at a directory (sometimes called a malformed request).

303

Another temporary relocation - This error code is much the same as error code 302, but the web page was requested slightly differently. As with error code 302, you will probably be forwarded to the correct URL.

Client Error Messages

Bad Request - The request could not be understood by the server due to bad syntax. You should not repeat the request without modifications.  Error in request syntax.

401

Access denied/Unauthorized - This usually shows up when you have tried to access a file or page that requires a login and password and you typed it incorrectly. Alternatively, you may simply not have permissions for that page or file. You should only retry the request if you know you authorization

Request requires an Authorization: field, and the client did not provide one. This response is accompanied by a list of acceptable authorization schemes use WWW-Authenticate response headers. Error 401 can be part of a client/server dialogue to negotiate encryption and user authentication schemes.

402

Payment Required - The requested operation costs money, and the client did not specify a valid Chargeto field. Payment was required in order to access the requested web page. The message should give a specification of charging schemes which are acceptable.

403

Forbidden - Request for forbidden resource denied. Sometimes you will get these by accident if the webmaster has incorrectly set the permission levels for a file or page. Even if you have a valid login and password for this file/URL, you will still be denied access.

404

Requested URL not found Page not found - Requested resource not found.  This is the most common one you will see. There are generally two causes. One is that you typed the URL incorrectly (or the link you clicked on was typed incorrectly), and the other is that the HTML page you are trying to view does not exist anymore. Make sure that the Web address (URL) that you typed in exactly matches the address you were given. Check that the capitalization matches, spelling, and punctuation, like dots (.) and slashes (/), are correctly placed. Be sure you are using the forward slash (/) and not the backward slash (\).

Method Not Allowed - A 405 error means that the folder where dtSearch Web is installed does not have "Execute" permission enabled.

None Acceptable - The server has found a resource matching the request URL, but not one that satisfies the conditions identified by the Accept and Accept-Encoding request headers.
