Error Occurred Status Code 302
- general The 302 response from the Web server should always include an alternative URL to which redirection should occur. If it does, a Web browser will immediately retry the alternative URL. So you never actually see a 302 error in a Web browser, unless perhaps you have a corrupt redirection chain e.g. URL A redirects to URL B which in turn redirects back to URL A. If your client is not a Web browser, it should behave in the same way as a Web browser i.e. immediately retry the alternative URL. If the Web server does not return an alternative URL with the 302 response, then either the Web server sofware itself is defective or the Webmaster has not set up the URL redirection correctly. Fixing 302 errors - CheckUpDown Redirection of URLs may occur for low-level URLs (specific URLs within the Web site such as www.isp.com/products/index.html) when you reorganise the web site, but is relatively uncommon for the top-level URLs (such as www.isp.com) which most CheckUpDown users ask us to check. So this error should be fairly infrequent. The 302 response from the Web server should always include an alternative URL to which redirection should occur. If it does, CheckUpDown automatically tries the alternative URL. This in turn may possibly lead to another redirection which CheckUpDown then tries. This continues for a maximum of 5 redirections. As soon as 5 redirections have occurred, CheckUpDown gives up and reports the 302 error for your account. So you should only ever see the 302 error if 1) the Web server gives no alternative URL on the 302 response or 2) the number of redirections exceeds 5. This second condition should be fairly unlikely - and may indicate a recursive pattern e.g. URL A redirects to URL B which in turn redirects back to URL A. You first need to check that the IP name we use to check for your account is accurate. If you or your ISP have configured something

When visiting Web sites, the client application makes connections to Web servers via a network protocol http://www.checkupdown.com/status/E302.html called HTTP. These network connections support sending response data from servers back to clients including the content of Web pages and also some protocol control information.Types of HTTP Error and Status CodesIncluded in the HTTP server response data for each request is a code number indicating the result of the request. These result codes are three-digit numbers divided into categories as follows:100-199 : http://compnetworking.about.com/od/networkprotocolsip/tp/http-error-and-status-codes-explained.htm informational status200-299 : success status300-399 : redirection status400-499 : client errors500-599 : server errorsOnly a few of the many possible error and status codes are commonly seen on the Internet or intranets. Codes related to errors are typically shown in the Web page displayed as output of a failed request, while other codes are not displayed to users. • HTTP 200 "OK" The Web server processed the request successfully and transmitted content back to the browser. Most HTTP requests result in this status. Users rarely will see this code on the screen as Web browsers generally only show codes when there is some problem. • HTTP Error 404 "Not Found" The Web server could not find the requested page, file, or other resource. HTTP 404 errors indicate the network connection between client and server was made successfully. This error most commonly occurs when users manually enter an incorrect URI into a browser or the Web server administrator removes a file without redirecting the address to a valid new location. Users must change their URL to fix this problem. • HTTP Error 500 "Internal Server Error" The W
consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status http://www.restapitutorial.com/httpstatuscodes.html codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental http://www.csgnetwork.com/servererrors.html conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, error occurred or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) Wikipedia Request received, continuing process. This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status error occurred status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions. 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. Wikipedia This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100-continue as a header in its initial request and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue). 1

Connection Errors & Web Server Response Codes And Messages Server Error Information There are two classifications of server errors, they are: Connection Errors - These errors are created as a result of a connection failing to be established to a Web server. They do not have a response code but will contain a brief description of why a connection could not be established. The reason that they do no have a response code is that Web servers can only return a response code after a connection is established, and since a connection could not be established to the Web server, a response code could not be obtained. Web Server Response Codes And Messages - If a connection was established to a Web server, the Web server usually sends a response code and message. If the response code is less than 400, the Web page is considered not on error. If the response code is equal to or greater than 400, the Web page is considered on error. The following listing includes a detailed definitions of all the errors that a web or intranet server generally returns and an explanation of each. Connection Errors Invalid URL Invalid URL simply means that the format of the URL was invalid. The format should be in one of the following forms: http://www.anyurl.com http://www.anyurl.com/ http://www.anyurl.com/page.jsp http://www.anyurl.com/page.asp http://www.anyurl.com/page.html http://www.anyurl.com/page.shtml http://www.anyurl.com/page.jsp?QueryString Host Not Found Host Not Found occurs when the web server's host computer could not be found using it's host/domain name (the Fully Qualified Domain Name). This usually indicates a problem with your DNS system or connectivity to your DNS system or general Internet connectivity problems. Time Out A Time Out occurs when a the web server's host computer was found using it's host/doma
