address, perhaps because an invalid host name was used or because no DNS lookup service is available. The browser could not connect to the web server. This may happen if the web server is not running or is listening on the wrong port.

The codes are grouped by the first digit: 1xx - Informational Any code starting with '1' is an intermediate response and indicates that the server has received the request but has not finished processing it. For example, IIS initially replies with 100 Continue when it receives a POST request and then with 200 OK once it has been processed (See 6. Methods) 2xx - Successful These codes are used when a request has been successfully processed. For example, the value 200 is used when the requested resource is being returned to the HTTP client in the body of the response message. 3xx - Redirection Codes starting with a '3' indicate that the request was processed, but the browser should get the resource from another location. Some examples are: 302 The requested resource has been temporarily movedand the browser should issue a request to the URL supplied in the Location

When I click a button on my site (localhost), I can see the server passing back the correct information but on the front end I http://stackoverflow.com/questions/32878613/networkerror-failed-to-execute-send-on-xmlhttprequest get this error: error: NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://comp-ip'. var param = JSON.stringify({varA:"varA",varB:"varB"}); $.ajax({ type: "POST", url: "http://comp-ip", async: false, data: param, success: function(result, status, xhr){ alert(result + ": " + status); }, error: function(xhr, status, err) { alert(status + ": " + err); } }); It seems to be triggering an error every time and not 'success'. Anyone have any idea what is wrong? Edit: I've tried sending a normal POST request without AJAX and it throws me an 'undefined' error as well: $(document).ready(function(){ var param = JSON.stringify({varA:"varA",varB:"varB"}); $("#btn").click(function(event){ $.post( "http://ip", param, function(data) { $('#container').html(data); } ).fail(function(error) { alert(error.responseJSON) }); }); }); Other things I've tried: 1) Changing browsers to Safari (same thing, server returns information but the site gets an error) 2) Setting async = true from false. For some reason when I set it to true, the server doesn't respond at all. When it's false the server responds. jquery ajax http-post share|improve this question edited Oct 1 '15 at 3:11 asked Oct 1 '15 at 2:41 Moo33 4152617 add a comment| 2 Answers 2 active oldest votes up vote
messages, except those with a severity level of debug or internal error. It contains these topics: Message Format Messages that Reference Network Security Messages https://docs.oracle.com/cd/B14099_19/caching.1012/b14046/event.htm (NZE) Message Listing Message Format OracleAS Web Cache rates each message by http://www.csgnetwork.com/servererrors.html severity level: class="msg" 9: A normal activity, for example, the start up or shut down of the cache server or an event log rollover. class="msg" 8: Information that helps trace the activity of OracleAS Web Cache. These messages are particularly helpful in debugging caching rules. Messages with failed to a severity level of trace are written to the event log file only when a Verbosity of Trace is selected in the event log configuration. class="msg" 7: An event which is abnormal or potentially a sign of a problem, but OracleAS Web Cache will continue to operate without any lack of service. For example, a request header included a malformed failed to execute header, but OracleAS Web Cache interpreted it in some way and continued processing. class="msg" 6: An event which can cause lack of service only within the request/response transaction. For example, OracleAS Web Cache cannot continue the transaction because of malformed request. class="msg" 5: An event which can affect an OracleAS Web Cache instance and can cause lack of service in a subsequent request/response transaction. For example, the origin server is not reachable or sufficient memory is unavailable. In many cases, the cache server will be shut down when an alert event is encountered. In addition, OracleAS Web Cache provides messages, that are not included in this appendix, with severity levels of debug or internal error: class="msg" 4: Contact Oracle Support for assistance. class="msg" 3: Intended for use only by Oracle Support. Messages that Reference Network Security Messages (NZE) Several SSL-related errors are reported with NZE errors in the event log. Oracle Database Error Messages lists these errors in full, and "Resolving Common NZE Errors" describes the most commons NZE errors reported to the event log. Message Listing 008

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/domain name, but a connection could not be established within a predetermined set time. The default time out is set to 90 seconds. This usually indicates a problem with your routers or firewall, or a web server hardware failure, or general Internet connectivity problems. Connection Refused A Connection Refused error occurs when the web server's host computer is found, but the host computer refuses to accept
