http-status-code-503

问题 We are planning a maintenance window for some of our sites (say at a.b.com, b.b.com and c.b.com). What we would like to do is to return a 503 return code for a holding page sitting on our main site (which is powered by a Tridion CMS database) (say at www.b.com/maintenance.html) as that site is not undergoing maintenance. Is that possible? We know you can create an app_offline.htm file in the root of each of the applications undergoing maintenance, but that would require us to build a

问题 I am trying to setup Dashbuilder. I have worked through a couple issues already (one with the help of others here, thank you). I am at the point where the program must be compiled, built, and run using command ./buildandrun.sh h2 things start off as expected, but then just stop at "[INFO] Started Jetty Server" in terminal.

问题 I have a node app with the server hosted on heroku. All my requests are successful until I have sent about 10 or 15. Then I start receiving CORS errors. Any idea why this could be occurring? Give it a try. http://danielrasmuson.github.io/ Here is my 'CORS Enabling Code'. I'm trying a few things at this point. var app = express(); app.use(cors()); app.all('/*', function(req, res, next) { res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "X-Requested

问题 I got the following message from the browser when I ran a long waiting request on my web application: Message from the NSAPI plugin: No backend server available for connection: timed out after 10 seconds or idempotent set to OFF. Also, I got a 503 response code from httpConnection. I assume the server was timeout, but I could not find anything to extend the timeout.

问题 I just installed Node.js, got it working for a while, then tried to run a standard Hello World program. var http = require("http"); http.createServer(function (request, response) { // Send the HTTP header // HTTP Status: 200 : OK // Content Type: text/plain response.writeHead(200, {'Content-Type': 'text/plain'}); // Send the response body as "Hello World" response.end('Hello World\n'); }).listen(8081); // Console will print the message console.log('Server running at http://127.0.0.1:8081/');
