Your application is responsible for starting a webserver and handling requests. This makes using the API very sluggish. Advantage: The requests are dealt in realtime. The synchronous model is appropriate if your application should block while waiting for a client request and if you want to process only one *request at a time*. Actions of controllers marked with session ReadOnly attribute will be executed in parallel: [SessionState(System. This might be a browser specific quirk. 4. The latter is responsible for handling POST requests for web services messages and thus needs a WebServiceMessageFactory In this case, the client would call two different endpoints to construct the objects it needs. Can I apply multi threading on my side to consume this web service in multiple threads and combine the results together? Executor framework, ThreadPoolExecutor. There's a downside: if you write a long-running method, its execution will block the main loop until it's finished. Whether that action is rendering a list of users or storing the results in your app for later use. That is to say, if single client will send some simultaneously requests to server, all of them will be executed sequentially and won't be executed concurrently. You can use any web framework that is available for your development language. ASP. However, this is not the case and all 3 requests pass ending up with 3 vouchers in database. This is one of the reasons why the server's unsuitable for production use. Service C starts up a daemon thread checking the message numbers in Redis. However, it can not handle multiple requests, it waits for one requests to finish and then handles second requests. So you would use e BeginGetContext and EndGetContext methods. Web. If this singleton instance gets request 1, and while handling that request, it gets another request (request2). But, what I'm really looking is, what is the best practice to handle multiple web requests efficiently?All those requests are independent to each other. Single Device Requesting Multiple Times Multiple Device Requesting Multiple Times In Both the In Both the Scenario i am not able to handle multiple Request, I don't know what is the actual problem but it's keep giving me the 403 Response and The best way to test this is to use Axis to write a web service client, and use it to fire a large number of requests at your server. If you want to know which thread is handling the current request, add this to your controller method: What you seem to need is a Asynchronous HTTP Handler. WebService { [WebMethod] public string HelloWorld() { throw new IndexOutOfRangeException("just a demo exception"); } } Now, on the client side, I want to be able to handle different exceptions in Your facade, after restart, must take all pending requests from the (persistent) queue and push them to REST clients. July 30, 2014, 10:50 pm Author: James Griffiths If you are like most front-end developers you'll no doubt be familiar with using jQuery to parse AJAX requests when handling data such as JSON or XML. push(httpRequest(options, JSON. This implies REST clients can detect if they already processed that particular request (and it just happened, facade hadn't processed reply before it went down). I completely disagree with @keysl, if you're creating an API you should probably be thinking of making it RESTFul and rest services should be idempotent, take a read of this article perhaps: "In the context of REST APIs, when making multiple identical requests has the same effect as making a single request" What this is likely to do it force IIS to spin up another instance, since it believes the previous call is still being processed. With the help of this we can avoid I have read many questions regarding handling multiple requests asynchronously in one view controller. It is part of the java. So there will be trade-offs. Any request can be routed to any instance, so consecutive requests from the same user are not necessarily sent to the same instance. This traffic is coming from automated security scanners. post() like yours is run in response to an event on the queue announcing an incoming web request. When I run a stress test with 50 concurrent get events, the response time is increasing A LOT, even tho the operation is quite simple, return 200 OK with the id typed in the uri. what will be the best approach to handle multiple concurrent requests along with async and await ? 2. I have several tools joined into the framework of integrated tools. Requests are handled individually and block each other from executing until they complete. This becomes an issues when I have multiple requests coming in, each one is executed one after another. I have a singleton client class in my solution, which calls an external service/APIs. So can Apache with mod_php, though in this case PHP is embedded in Apache and limits what Apache can handle. The number of simultaneous requests that can be processed is directly related to the size of this thread pool. Why don't you minize the time between the PostRequest. This I have a Java program that sends hundreds of GET requests to a server using Java 11 HttpClient, and it needs to do this 2-3 times every minute. Should I handle the state of the queues in memory instead? Often, it is best to make web application stateless and requests independent. Advantage: The first request is never sent (you save server load). Regarding the mish mash, for the DB, handling 10 requests within 1 second is the same as 10 requests within 10 seconds, it won't confuse them and just execute them one after the other. This approach ensures that only the I want to send multiple HTTP requests to a web service using C# client, just to stress the web service. The simple way to address that will be to write a goroutine that sends the userID values to a channel and then start up some limited number of goroutines that read from the channel and make the requests. The number of instances can be How to handle multi users' requests separately in Flask? 1 How to process several HTTP requests with Flask. How you scale is to load-balance your service across multiple CPUs/servers instead of using ffmpeg directly: How does a single servlet handle multiple client requests coming in the form of user requests ? Based on the singleton design pattern I know we get a single instance of servlet created , but how does a single servlet handle millions of requests . xupzhf bghue csxatsx iidbn zgkjpa ilxz tlmzu fppcv adxtb lqsonug
