http-status-code-503

问题 I have an Azure service that has been running for a long period of time. It builds a word or powerpoint document based on arguments in the request and returns a uri to the build document. This is access via a visualforce page, when you click a button, it calls the service and displays a link to the document that has just been built. Simple. All of a sudden, I get an apparently random 503 Service Unavailable error. Sometimes I click the button, no problem. Other times a 503 error. Each time

问题 I have apache2 and tomcat6(not installed from apt repository, manually downloaded and installed) running on port 80 with mod_jk setup. The jsp servlet pages are accessed pointing the browser to http://myapp.mydomain.com/ (virtual hosting is done in tomcat(server.xml) and in apache). I'm trying to redirect tomcat's error page 503 to custom error page when tomcat is down(pkill -9 java or /etc/init.d/tomcat stop) during deployment. My apache's Document Root is /var/www/ so I place below entry in

问题 I need to send a Customized Error page for 503 Errors produced by my asp.net website. I have tried to simulate the condition by switching off the application pool (doesn't work) and by flooding my application with requests. Even though IIS sends me the default 503 error page, and even though I have tried setting a Custom URL in IIS and ASP.NET for this error code, it still returns me the default 503 error page ! I'd appreciate if someone could also tell me where the default 503 error page is

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . we have a asp.net MVC application deployed to a server, and but when there is too many request to the server, the client will just get a "503 service unavailable" error. But if I deployed the application to another server ( lower hardware configuration ), everything worked fine,

问题 I'm trying to use NancyFx in combination with SignalR. In order to host both, I'm using Microsoft Owin. But unfortunately I always get an 503 (Service unavailable), when trying to access the REST-API via PostMen (REST-Api Client extension for chromium browsers). So I extracted the main ingredients to a more simple program, that allows me to switch between Nancy Selfhost and Owin. When using Nancy SelfHost, everything works fine, but using Owin I still got a 503 error. internal class Program {

问题 I'm running cPanel on a Rackspace cloud server that's hosting about 30 websites. I'm using Varnish 3.0.3 + Apache 2.2.23. I'm getting random 503 errors. If I restart the httpd process, they go away. I checked the Apache error_log, and I don't see anything related to a 503 error. Here's my Varnish config: backend default { .host = "198.61.161.65"; .port = "8080"; .connect_timeout = 600s; .first_byte_timeout = 600s; .between_bytes_timeout = 600s; } Here's my Varnish startup parameters: -a :80

问题 For the past couple of days, every time I try to run my web application, Error - 503 has been showing up. This happens even when I try to go to the admin page. Is this a problem with Google? 回答1: It's important when creating a GAE project that any .class that extends HttpServlet and are used as entry point to your Google App are mapped in web.xml found in war/WEB-INF as pictured below. Java Servlets you create that extend HttpServlet must be mapped in the web.xml like the following:- In this

问题 I have the strangest problem. This is my javascript: var value = "some_value"; $.ajax({ url: "process.php", type: "POST", dataType: "json", data: { value: value }, success: function(data) { console.log(data); } }); No surprises here. This is my process.php: <?php exit; ?> Actually it does not matter, what is inside the process.php . The request is successful everytime, except when value is a valid URL. With var value = "http://example.com" at the beginning the request will fail with error 503

问题 I'm conducting a series of queries to DBpedia SPARQL endpoint (from inside a loop). The code looks more or less like this: for (String citySplit : citiesSplit) { RepositoryConnection conn = dbpediaEndpoint.getConnection(); String sparqlQueryLat = " SELECT ?lat ?lon WHERE { " + "<http://dbpedia.org/resource/" + citySplit.trim().replaceAll(" ", "_") + "> <http://www.w3.org/2003/01/geo/wgs84_pos#lat> ?lat .

问题 Some hours my web site's server has too much load. Which HTTP status code should I send to the Googlebot that visits my website? Is " 269 Call Back Later " this suitable for this case, or 503 Service Unavailable or do you have any more suggestions? 回答1: 503 means the service is temporarily unavailable so it is appropriate to use while the server is overloaded. http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html The Wikipedia article defines 269 as the initial response for a request that
