How Does IIS Handle Large Volume Of Requests
Jul 26, 2010I have a standard ASMX web service which uses a lock object to process the first request it receives and reject other requests that come in before processing completes. The web service is hosted on a Windows Server 2003 box with a single-core processor. To test whether this works as expected, I wrote a client that spawns 100 threads. Each thread makes an asynchronous POST call to the web server (i.e., HttpWebRequest.BeginGetResponse()). From my own logging, what I'm seeing on IIS is that two threads are spawned. Let's say thread IDs 1 and 7. Thread 1 is assigned a small number of requests. It accepts and processes them, one after another. Thread 7 is assigned a large number of requests. It rejects them. Does anyone have theories on the following: Why are two threads spawned? And not four or a hundred? Why does there seem to be thread discrimination? Thread 1 looks like it has control of the lock object at all times.

How To Page Through Large Volume Of Data
Nov 19, 2010I'm creating a web page that will show a form that allows a user to query a database and then page backwards and forwards through the data. In other words one record of the returned data will be displayed on the form and the user can move forward to display the next record or back to display the previous one.
My problem is that a large volume of data may be returned and I'm wondering the best way to keep this data between postbacks. I would think there would be too much data to use viewstate.
C# - Sending Large Volume Of Emails Using C#?
Jan 20, 2010I'm having an issue sending large volumes of emails out from an ASP.Net application. I won't post the code, but instead explain what's going on. The code should send emails to 4000 recipients but seems to stall at 385/387.
The code creates the content for the email in a string.
It then selects a list of email address to send to.
Looping through the data via a datareader it picks out the email address and sends an email.
The email sending is done by a separate method which can handle failures and returns it's outcome.
As each record is sent I produce an XML node in an XML document to log each specific attempt to send.
The loop seems to end prematurely and the XML document is saved to disk.
Now I know the code works. I have run it locally using the same SMTP machine and it worked fine with 500 records. Granted there was less content, but I can't see how that would make any difference.
I don't think the page itself times out, but even if it did, I was sure .Net would continue processing the page, even if the user saw a page time out error.
Keeping A Large Volume Of Data In Session?
Mar 23, 2010I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance.
So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits.
If the user then looks at their contacts again the data will just come from the local DataTable.

Can MVC Handle Regular URL Path Requests Too
Mar 3, 2011ASP.NET MVC newbie question:
I've set up a MVC site, with a few controllers. Now my site also has a lot of content files, which are stored in a network of subfolders within my web site, and I need to be able to access them directly, e.g.
[URL]
Is there a way to make this a direct pass-through to the content folder, as specified by the path, or do I have to make a Content controller that interprets the rest of the URL and returns the file as some kind of ActionResult? Bear in mind, of course, that there will be lots of different content types, not just JPEGs.
VS 2012 - How To Handle Ajax Requests In MVC
Jun 24, 2014This is sort of a continuation of a previous thread: View thread
The requirement I have is to be able to have a popup form that shows detailed data on a facility. This would be available on various pages of the website where the user may want to drill down and see detailed information on a facility. We also want to allow the user to update the data on the facility if so desired. I have the code working to show the popup form and get the html for the popup from a view. Right now I'm setting the values of the input boxes using razor code that accesses the @model object. That's about as far as I've gotten.
Where I'm struggling is:
1. How to tie the data in the inputs back to the view model.
2. How to write the ajax code to write the data back to the server. I tried using a standard form, but that redirects the original page that popped up the form. I want to leave that page alone and just submit the data back to the server and close the popup.
Now my dev lead wants us to use the dojo toolkit for our javascript library. That would be OK if I already knew what I was doing with regard to web development, but I don't - and documentation is just not very good with regard to dojo. I'm still trying to figure out html and mvc, so I thought I'd see if I can get this scheme working with some other javascript library first, and then see about switching it over to dojo.
I've read some about knockout and jquery, but with everything being so new to me it's hard to get all this to gel in my head, and I'm not sure about my design. I've read some about mvc's built in ajax tools, but so far all I'm seeing is stuff related to getting data and displaying it - not about submitting data.
I'd like to be able to send the data back to the server in the same object structure that I extracted it with - something that matches the model. I think this is doable, but I'm not sure - and the 'how' of it is escaping me at this point.
Submit A Form With A Large File Upload And Send Ajax Requests?
Mar 8, 2011This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.

MVC's AsyncController Be Used To Service Large Number Of Concurrent Hanging Requests (long Poll)??
Feb 13, 2011Frameworks like Node.js, Tornado, and Twisted let developers create server-push applications that supports large number of concurrent hanging requests (10k+). From what I understand, they all achieve this by not creating threads to service each hanging request.
Can AsyncController be used to service large number of inactive concurrent requests?If so, are there any reasonably large ASP.NET MVC websites using this approach to create long-poll applications?
How To Handle Every Request To A Folder (including Requests To Subfolders Within)

View 1 RepliesFileUpload Web Control Can't Handle Large Jpg Files (5MB)?
Jun 22, 2010I'm testing a very simple aspx page on Visual Studio's own ASP.NET Development Server(the local server). On the webpage there is a FileUpload control which can upload jpg file up to 2MB without problems. On uploading bigger files, the browser immidiately show "The web page cannot be displayed". It does not show any exception which really puzzles me. "The web page cannot be displayed" is normally caused by network problem, but in this case it's a local server and it can handle smaller jpg file fine. Whta's the problem here?
View 3 RepliesConfiguration :: Website Stops Working After Few Requests
Jan 27, 2010I developed and deployed a web application using ASP.NET,C# successfully. The application was running perfectly until few days back. [NOTE: It still works fine on local machine (tested using both development server and IIS)] What happens now is: The website opens perfectly. After few operations which involves database interactions, in all the pages, the pages stop responding. I mean, after a few clicks, if I try another operation the page starts postback for unlimited time period and never gets rendered
and a following message is given: The connection was reset: Firefox 3.5... IE cannot display the web page: IE 7, 8 There is no database connectivity issues. I checked event logs on the web server and found few unhandlled exceptions, I corrected those. Now the event log doesn't show any error. But the problem is same.
I tried accessing the page from web server's browser, everything works fine. Even my boss can browse all pages with no problem (both have Win Server installed). Other machines (mostly XP) can't browse after sometime(as described above). I checked the memory usage, cpu time - NO ISSUES.

Configuration :: Web Deployment Project 2008: Exclude Large Folder From Being Copied?
Mar 18, 2010I have a large folder (1.5 GB) in my ASP.NET Web Site, called Downloads, which contains media files, graphics, etc. No code that needs to be compiled or even deployed on every build.
I use Web Deployment Projects to compile and deploy. Every time I build the deployment project, the Downloads folder gets included and copied to the output location. This is taking a significant amount of time, because the folder is copied twice.
I've tried modifying the wdproj file like this:
<ItemGroup><ExcludeFromBuild
Include="$(SourceWebPhysicalPath)Download*"
/>
I've also tried not adding the * after the folder, but then I get a message that says the directory is not empty during the build process.
I've also tried this approach:
<ItemGroup>
<RemoveBeforeMerge Include="$(OutputPath)Downloads*" />
</ItemGroup>
And that still did not help. (also says: The directory is not empty.)What is the proper way to tell WDP not to consider a folder at all?

Configuration :: Handle Windows Authentication Login Popups Cancel Click?
Nov 2, 2010I have simple web application called App that is secured with Windows Authentication. I have set identity impersonate to true in web.config. There is only one page (Default.aspx) in App directory. When user enters the site ex.: http://localhost/App the login window pops up. When user clicks Cancel, IIS redirects to page with an error 401.2. I want to redirect to http://localhost/App/app_start/login.aspx. App_start is an aplication that is secured with Forms Authentication. I tried to handle programmatically the redirection by adding Application_EndRequest method in Global.asax file. But when user clicks Cancel the Application_EndRequest is not being fired. When user successfully logs in the method is being fired. Is there any way to handle error 401.2 programmatically or maybe in a different way?
Application_EndRequest code:
if (Response.StatusCode == 401)
{
Response.Clear();
Response.Write("You don't have access to content.");
