Application Pool may contain multiple worker processes (w3wp.exe) ?Application Pool may contain multiple Asp.NET Applications ?Asp.NET assigns one ThreadPool per AppDomain ?One AppDomain only contain one Web Application Instance but Application can contain multiple AppDomains ?
Edit : These questions are related to IIS 6x or higher, in which App Domains are available.
We are working on a web application that creates more web applications.Each web application will have to get a Url Rewrite rule (URL REWRITE MODULE 2.0).As far as I know, there's no way to add such rules without modifying the web.config file (am I right??).So my plan was to work with multiple web.config partial files. One main .config file, and lots of .config files per application (every file will contain it's web application url rewrite rules).This way sounds a little bit messy, but I can't think of anything else, and suggestions will be welcomed.
View 1 RepliesI have a custom ASP.NET application that I utilize for several clients that I host. Each client has a separate domain and the application is normally a child application under the root domain [URL]. The application files are the same (aspx, ascx, style sheets, images, etc.). The only thing different is the web.config file for each client. As development of the application continues to evolve, I have to update the application for each directory and this obviously becoming tedious. I am trying to come up with a method keep the application up to date. My first though is placing the application into a single physical path and creating multiple applications pointing to that path (the problem with this method is I can't have different web.config files). I am curious as to what solution others are using in this scenario...

When IIS restarts an ASP.Net (2.0) web application, it can either:
Recycle the AppDomain: Unload the AppDomain and load a new AppDomain on the same process (e.g. when HttpRuntime.UnloadAppDomain() is called, when web.config is changed).
Recycle the process: unload the AppDomain and load a new one on a new process (e.g. when invoking Recycle command on an AppPool via inetmgr, or when memory limit is reached).
Due to some internal reasons (trouble with legacy native code we depend upon), we cannot allow the first option. We just can't load the application twice on the same process.
Can IIS be somehow told to never allow worker process reuse?
I've tried preventing it myself by tracking whether an application has already started on a process once using a Mutex, and if so - throwing an exception during Application_Start()); I've also tried terminating the process by calling Environment.Exit() during Application_End(). The problem with both methods is that it causes any requests that arrive during Application_End or Application_Start to fail (unlike a manual process recycle, which fails absolutely no requests because they are redirected to the new process right away).
I've got an ASP MVC (1.0) application. It works fine locally via visual studio and on our dev server which runs IIS6. But when I try to deploy to the Test server (running IIS7 on Windows Server 2008 R2) I get only :"Could not load file or assembly '<ApplicationName>' or one of its dependencies. Access is denied" (where <ApplicationName> is the name of my application). This is followed by a "FileLoadException", a "ConfigurationErrorsException" and two "HttpException" (all with the same message as above)I deployed via publishing to an empty directory, whose contents were then zipped and transferred to the site directory on the test server. If I copy the directories contents to my IIS installation it works fine. I've checked that networkservices has permission to access the site directories and the temporary directories, which were the solutions I found via google,

What Can I do?
I have a web application and when I decided to test on IIS 7 i have this Exception when trying to load a couple of pages that uses Entity Framework 4. I use EF 4 with my own CRUD assemblies but sometimes using the EntityDataSource. I have noticed that the problem is not appearing in all my Web Pages but I think in those that I use the EntityDataSource.

I think its the EDM problem but I can't get through.
I should mention that in my development pc is working all perfectly!!!
My controls are DevExpress but I dont think this should play any role!

Forgot to mention that I use Self tracking Template with the Entities.tt in a separate assembly!

On my local Windows 7 IIS works OK! It's Windows Server 2008 I can't get it done!
I am using windows authentication without impersonation on my company's intranet website with IIS7.
Under IIS7, what account is used to access the folder which contains my web app using these settings?
Would it be IIS_IUSRS? Or NETWORK SERVICE? Or another I don't know about?
I wanna serve my application in ISS to be accessed from many different URL's on my web server.
eg.
http://example.com/test1
http://example.com/test2
Both these URL's get served by the same application.
I do NOT however want to just create new virtual applications to the application, because it stuffs up the user membership roles. The users and their roles must exist accross the two URL's.
I have published my site using Visual Stuido's 2008 publish feature. I have then copied these files to a windows 2008 web server with IIS7 installed, it also has .net 3.5 sp1 and MVC installed In IIS I added the site using the 'Add a new site' right click option and then pointed this at the directory my site files are located in, I used the default application pool and it is set to integrated. Then when I attempt to browse I got the error message The Web server is configured to not list the contents of this directory. So I added Default.aspx to the default document list and I then get the following error message
HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map. Has anyone got any ideas on what I do next ? I have read lots of articles on this online but most are confusing and dont explain the solution in simple terms Surely it should be pretty straightforard to just deploy an MVC website to IIS7
We have a set of about 30-50 users who periodically need an ASP.net (version 4) application directory created for them.
As these numbers grow, manually creating an application directory for each user becomes cumbersome on IIS 7.
Is there a way to create these application folders using a batched/scripted/automated mechanism of some kind?
Ideally we'd like to provide input parameters of a file that contains a batch of application-names, and have the script automatically create the application directories in IIS.
I have a number of ASP.NET (4.0) web applications that appear to leak (a small amount) of memory during each request. It is such a small amount, that for most use-cases, it will not grow to become a problem for weeks or even months at a time. I generally try to be good with closing any connections managed by the application, avoiding state-variables (or instance variables for my singleton), etc. My question is this - is this normal behavior for ASP.NET applications? I had turned off the default (IIS 7) behavior of recycling the app pool after 20 minutes of being idle. I do this since the application takes a few minutes to build its internal cache, and I want to avoid negatively impacting the user experience (and having them wait for the application to start when they issue the request).
View 1 RepliesI don't know if it's IIS, ASP.NET or IIS7 related. I take a chance here, if you think I'm in the wrong forum, just tell me which one I should post to.
I have made the smallest demo project to illustrate my problem. You can download the sources
Here
Visual Studio 2008, .NET 3.5, IIS7, Windows 7 Ultimate 32 bits. The IIS Website is configured
ONLY for Windows Authentication in an Integreated pipeline app pool (DefaultAppPool).
Here's the problem. I have an Asp.NET MVC 2 application. In an action, I start a thread. The View returns.
The thread is doing it's job... but it needs to access Thread.CurrentPrincipal.Identity.Name
BANG
The worker process of IIS7 stops. I have a window that says: "Visual Studio Just-In-Time Debugger An unhandled exception ('System.Object.DisposedException') occured in w3wp.exe [5524]"
I checked with the debugger and the Thread.CurrentPrincipal.Identity is valid, but the Name property is disposed.
If I put a long wait in the action before it returns the view, then the Thread can do it's job and the Identity.Name is not disposed. So I think the Name gets disposed when the view is returned.
For the sake of the discussion, here's the code that the thread runs (but you can also download the demo project. The link is on top of this post):

Pardon if this is more serverfault vs. stackoverflow. It seems to be on the border.
We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem:
The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server.
What we've tried so far:
In machine.config/system.web (sf doesn't allow the tags, pardon the formatting):
processModel autoConfig="true" memoryLimit="80"
In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting):
privateBytesLimit = "20000000000" (and 0, the default of course)
percentagePhysicalMemoryUsedLimit = "90"
Environment:
Windows 2008R2 x64
32GB RAM
IIS7
Nothing seems to allow us to exceed the 60% value.
See screenshot of taskman.

I am thinking about setting up a new domain to host static content on my website and have it cookieless just like Stackoverflow with their static domain. So before going ahead and buying the domain and setting it up I wanted to test it on my developement machine first under localhost (I have to mention that i am planning on having IIS running on my new domain for the static files). I therefore created a new application under IIS and disabled session state and forms authentication. When my main application needs resources like css, images and js , I use the path to the "static" application where they are hosted.
The problem is that when I look at the request and the response for the requested files, they still have the session_id cookie defined as well as the asp.net authentication cookie. Is it at all possible to accomplish what i am trying to do on a development machine or do i have to just go ahead and purchase the new domain which hopefully with make things right? I tried to read about cookieless domain but can't figure out what i might be missing.
What need to change in asp.net application if web server update from IIS6 to IIS7?
View 2 Repliesexactly as the question subject states - any ideas on how you might do this?I've been looking over the objects in System.Web.Hosting but nothing is standing out.
he reason? I'm getting one or two application errors which are typically occuring during a recycle (they happen about 25 hours apart and I've left my app pool recycle time at the default) and so I want to know if they're happening on a thread that's in the pool that's shutting down, or the one that's start(ed/ing) up.
I have a config file linked from web.config e.g.<features configSource="feature.config" />When I make changes to the "feature.config" file the IIS application appears to restart, is this expected behaviour?
View 1 RepliesI currently have 2 x ASP.NET 3.5 web applications in IIS7 (lets call them WebParent and WebChild).WebChild is nested within the WebParent listing in IIS7 and is set up as an application (rather than just a virtual directory within WebParent). Both currently use their own (Classic) application pool.Both WebParent and WebChild have their own fully defined web.config files in their own root directories.
View 3 RepliesI've noticed as my website gets bigger and bigger, the time my laptop takes to display my page is much longer then say a new projects with minimal references. I think there are two variables at play that affect ASP.NET warm-up time:
The quantity of external references The time it takes for a worker process to new() up each instance per worker process Additional time for the WCF objects as the ServiceHost may be in an external DLL First, are those the correct variables to take into account when considering ASP.NET startup time? Next, it appears that web.config may dispatch other objects for use with certain filetypes (*.svc, *.aspx, Windows Identity Foundation (WIF), etc. ). This too may cause delays in ASP.NET.
Last, my project is created as a "web project" not a "web site". Not sure if this has an impact. Is my theory full of holes, or is there something I can do to make development on a old laptop any better?
I'm stumped. I have a client site on a virtual private server - Windows Web Server 2008 SP2, IIS7, SQL Server 2008 Express.I'm trying to setup a second web application, to allow him to review updates prior to their going live. I've created the web application in IIS7, and I have added a second database to SQL Server. The second db is essentially a copy of the production db, with 'DEV' prefixed to the database name and a few new fields in a few tables.My production site works fine. However, the test site comes back with an SqlException: "Invalid column name 'version'." This is one of the new fields - which leads me to believe that my dev site is referring to the production database, and not the dev database. Connection strings, however, do point to different databases (although the login is the same for both):

I'm working on an ASP.NET application that accesses Team Foundation Server 2010 and creates new work items. The application is running in the DefaultAppPool, using NetworkService as the identity. I'm getting the error below:

We were able to work around the issue by turning the Cache folder into a network share and giving NetworkService full access to the share. I'd prefer not to have to do this, but it seems to be working correctly now.
