It appears that this HttpException (0x80072746 - The remote host closed the connection) can be thrown if, for example, the user closes the window whilst we are transmitting a file. Even if we send the files in smaller blocks and check the client is still connected, the exception can still occur. We want to be able to catch this specific exception, to ignore it. The ErrorCode provided in the HttpException is an Int32 - too small to hold 0x80072746, so where do we find this number? Int32 is not really too small to hold 0x80072746; only in “normal” notation, this number is negative: 0x80072746 ==

I want to stream data from an IHttpHandler class. I'm loading a large number of rows from the DB, serializing, and compressing them, then sending them down the wire. On the other end, I want my client to be able decompress, and deserialize the data before the server is even done serializing all the objects. I'm using context.Response.OutputSteam.Write to write my data, but it still seems like the output data is being put into a buffer before being sent to the client. Is there a way to avoid this buffering? The Response.Flush method should send it down the wire; however, there are some

Consider a Web.config file containing the following httpHandlers declaration: <httpHandlers> <add verb="*" path="*" type="MyWebApp.TotalHandlerFactory"/> </httpHandlers> In other words, this handler factory wants to “see” all incoming requests so that it gets a chance to handle them. However, it does not necessarily want to actually handle all of them, only those that fulfill a certain run-time condition: public sealed class TotalHandlerFactory : IHttpHandlerFactory { public IHttpHandler GetHandler(HttpContext context, string requestType, string url, string pathTranslated) { if (some condition

Im constructing an array of objects like this: var postData = []; $.each(selectedFields, function (index, value) { var testTitle = 'testing ' + index; postData.push({title: testTitle, title2 : testTitle}); } I then post it like this(note that i have tried a number of different aproaches): $.post('SaveTitlesHandler.ashx', { form : postData }, function (data) { console.log(data); }); I then try to get the data in a handler... public class SaveTitlesHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { string json = context.Request.Form.ToString(); } } I cant seem to get

I have the following file upload handler: public class FileUploader : IHttpHandler { public void ProcessRequest(HttpContext context) { HttpRequest request = context.Request; context.Response.ContentType = "text/html"; context.Response.ContentEncoding = System.Text.Encoding.UTF8; context.Response.Cache.SetCacheability(HttpCacheability.NoCache); var tempPath = request.PhysicalApplicationPath + "\\Files\\TempFiles\\"; byte[] buffer = new byte[request.ContentLength]; using (BinaryReader br = new BinaryReader(request.InputStream)) { br.Read(buffer, 0, buffer.Length); } var tempName = WriteTempFile

I've never fully understood this property of the IHttpHandler . It is a property that you have to set when you implement the interface. I've assumed that setting it to true would be better for performance, but I am not sure what the negative side effects might be. Should I return true or false? It is used to indicate if a single instance of the IHttpHandler will be used to process multiple concurrent requests. So if you set it to true it will improve performance but you must make sure that your code is thread safe because the ProcessRequest method might be invoked from multiple threads at the
