问题 What is the best option for writing (appending) records to file in highly parallel web environment in .net4 IIS7? I use ashx http handler to receive small portions of data that should be written to file quickly. First I used: using (var stream = new FileStream(fileName, FileMode.Append, FileAccess.Write, FileShare.ReadWrite, 8192)) { stream.Write(buffer, 0, buffer.Length); } But I noticed that some records were broken or incomplete, probably because of FileShare.ReadWrite. Next I tried to

问题 I am trying to reproduce a threading error condition within an HTTP Handler. Basically, the ASP.net worker procecss is creating 2 threads which invoke the HTTP handler in my application simultaneously when a certain page loads. Inside the http handler, is a resource which is not thread safe. Hence, when the 2 threads try to access it simultaneously an exception occurs. I could potentially, put a lock statement around the resource, however I want to make sure that it is infact the case. So I

问题 I've looked all over, and I can't find a solution for this. Correction: I find solutions, but they (I can't make them) work. I'm passing an array to an HttpHandler via the query string. I've read that you read it this way: Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest Dim request As HttpRequest = context.Request For u = 0 To request.QueryString("arrayIneed").Count - 1 selectPONumber.Add(request.QueryString("arrayIneed")(u)) Next Doing this, regardless

问题 Original post: This web application sends out emails which contain a link to a URL. Correction-Clarification 9/17/2014: An .EXE running as a scheduled task on a server (in "support" of the web app and connecting to same database) sends out emails which contain a link to a URL. The nature of the email content is essentially a "reminder"; the link when clicked is essentially an acknowledgement signaling "done". Resumption of original post follows: Clicking the link in the email does 2 things at

问题 I have a custom IHttpHandler, specified in web.config as follows: <httpHandlers> <add verb="*" path="*.html" validate="true" type="PipingRedirectHandler" /> <add verb="*" path="*.htm" validate="true" type="PipingRedirectHandler" /> </httpHandlers> In IIS 7 (on Win 2008 R22) I added handler mappings with Path: *.html/*.htm and executable: %windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll . I also have a virtual directory mapped to a windows share on another machine, Alias:

问题 I am developing a custom HttpHandler, to do so I write a C# Class Library and compile to DLL. As part of this I have some directory locations which I want not hard coded in the app, so i'm trying to put it in the app.config which I've used before. Before this has worked by just going building the app.config: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="Share" value="C:\...\"/> </appSettings> </configuration> And then obtaining this in code like: var

问题 I haven't used httpHandlers before in MVC. However I want to stop session timing out in my application. I found the solution here; http://www.dotnetcurry.com/ShowArticle.aspx?ID=453 However with my implimentation I get the error message The controller for path '/Shared/KeepSessionAlive.ashx' was not found or does not implement IController So the jquery; $.post("/Shared/KeepSessionAlive.ashx", null, function () { $("#result").append("<p>Session is alive and kicking!<p/>"); }); is looking for a
