ASP.Net: IHttpAsyncHandler and IRequiresSessionState not working

由 北战南征 提交于 2019-12-08 13:10:48
问题 I have implemented an IHttpAsyncHandler. I am making about 5 different AJAX calls from a webpage that has widgets to that handler. One of those widgets takes about 15 seconds to load(because of a large database query) the others should all load in under a second. The handler is responding in a synchronous manner. I am getting very inconsistent results. The ProcessRequest method is using Session and other class level variables. Could that be causing different requests to use the same thread

IIS 7.0 503 errors with generic handler (.ashx) implementing IHttpAsyncHandler

问题 I'm running into some performance issues using a generic handler that implements IHttpAsyncHandler. At its simplest, the handler receives a GET request, and 20 seconds later ends the response after writing '< timeout / >' to the response. When hammering the .ashx with 10000-20000 simultaneous requests, it fails with 503 server unavailable after precisely 5000 requests. When switching to synchronous mode, and ending the request immediately, the problem goes away. I've tinkered with a number of

What is the best way to upload files with ASP.NET MVC 2?

What is the best method for uploading files of variable size (either very large or very small to an ASP.NET MVC 2 application file system)? This is what I understand so far: It seems like there are two ways that people handle this. (Let's assume the files may be very large or very small) (1) Handle the upload in a controller action via Request.Files or HttpPostedFileBase , which seems to have a drawback of taking a long time because ASP.NET loads the files into active memory. or (2) intercept the file upload early on with an HttpModule which somehow circumvents the performance issue. (I'm a

Using an IHttpAsyncHandler to call a WebService Asynchronously

问题 Here's the basic setup. We have an ASP.Net WebForms application with a page that has a Flash application that needs to access an external Web Service. Due to (security I presume) limitations in Flash (don't ask me, I'm not a Flash expert at all), we can't connect to the Web Service directly from Flash. The work around is to create a proxy in ASP.Net that the Flash application will call, which will in turn call the WebService and forward the results back to the Flash application. The WebSite

Using Task or async/await in IHttpAsyncHandler

问题 Since the very begining of writing ASP.NET applications when I wanted to add a threading there are 3 simple ways I can accomplish threading within my ASP.NET application : Using the System.Threading.ThreadPool . Using a custom delegate and calling its BeginInvoke method. Using custom threads with the aid of System.Threading.Thread class. The first two methods offer a quick way to fire off worker threads for your application. But unfortunately, they hurt the overall performance of your

What is an HttpHandler in ASP.NET? Why and how is it used? In the simplest terms, an ASP.NET HttpHandler is a class that implements the System.Web.IHttpHandler interface. ASP.NET HTTPHandlers are responsible for intercepting requests made to your ASP.NET web application server. They run as processes in response to a request made to the ASP.NET Site. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler. ASP.NET offers a few default HTTP handlers : Page Handler (.aspx):
