Using IIS 6, is Application Isolation happen based on the Application Pool? If so, what happens when there is more than one Virtual Directory in one Application Pool? Do they all share the same memory and if one Virtual Directory crashes, all the other apps crash as well?

I'm building a multi-tenant ASP .NET application. Given that each tenant can configure their application dynamically (which may involve dynamic custom assemblies being loaded into memory), I need a means of isolating each tenant.
I'd prefer not to create a new Web Application per tenant for maintenance reasons.
I've was considering using the AppDomainManager to create an AppDomain per application, but it seems this is not intended to be used for ASP .NET applications.
I am migrating an existing set of applications from Win XP to Win 7. We have a 3rd party application which is launched by and runs in the user's session which accesses a local SQL Anywhere 9 database via ODBC (launched on demand using dbeng9). On the same machine we have an ASP.NET website which also accesses the local SQL Anywhere database via ODBC. These two applications play nicely together in Win XP because both processes are running in Session 0.
In Win 7 the ASP.NET site encounters an ODBC error stating that the specified database file is already in use. This is because the 3rd party app starts first and spins up an instance of dbeng9 (via ODBC) in the user's session (usually Session 1). Then, the ASP.NET spins up and attempts to connect to the same database. The ODBC driver sees that an instance of dbeng9 is not running in the current session (Session 0) and attempts to spin up an instance at which time it is unable to access the database file because it is already in use by the logged on user in Session 1.
Does anyone have any suggestions for solving session isolation issues with local SQL Anywhere databases?
I thought about running dbeng9 as a service rather than allowing ODBC to spin up an instance on demand. However, because SQL Anywhere is bundled with the 3rd party product the PCs do not have dbsrv and I'm not sure how this would impact the licensing.
The ASP.NET site is only accessed from the local PC. Would running the ASP.NET site in a 3rd party web server cause it to execute in the user's session? (Note: because this runs on 1,000 machines a free or very low cost option is a must.)
Is the ASP.NET Development Server that is bundled with Visual Studio redistributable in this manner?
Can IIS 7 or IIS 7 Express be configured to run in "local only" mode in which it executes in the
user's session?
I am implementing an Isolation test in my project to ensure the data is the same in the as it was when originaly retrieved before submitting the new form data.I was wondering what would be the best way of handling this error (not an exception). The following code is the function that will determine whether or not an error should be reported, If 1 or more fields of the current record is different from the original it will return false, otherwise it will return true. How should I go about handling a false response for a best practice, Should I use a statcode and transfer to the main page displaying a message with the state code, or should I send a simple msgbox, or simply just log the error and transfer the user to main page.

I am using ShDocVW.InternetExplorer class to spawn a new internet explorer object and to do some form filling stuffs(for some sharepoint works).It works fine in my own machine which has Windows 7 as the OS. But when I deployed the same thing in windows server 2003 machine, it does not pop up the internet explorer window. When I check the Task Manager, I could see a new iexplore process, but with Session ID = 0 (but session ID = 1 in windows 7). So, I see this is something regarding IIS Session isolation.So, is it possible to assign a ShDocVW.InternetExplorer instance to kind of a new System.Diagnostics.Process and achieve this task? Or can we start a new ShDocVW.InternetExplorer instance with session ID = 1?

Both the applications are using the same service then way there is a time span problem. Please suggest me what can I do to improve performance of application A?
I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send
e-mails from addresses within the
domain to adresses within the domain,
but not to addresses outside of the
domain.
A Windows Forms application running
the same code on the same computer
can send e-mails from ANY address to
ANY address.
Another ASP.NET application on the
same IIS running under the same
account (NETWORK SERVICE) can send
e-mails using the same SMTP-server
from ANY adress to ANY adress.
There is no authentication configured
on the SMTP-Server.
Both the ASP.NET application and the
Windows Forms application utilizes
the System.Net.Mail.SmtpClient class
to send a
System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e)
{
MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text);
SmtpClient client = new SmtpClient();
if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty
client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text);
client.EnableSsl = false;
client.Host = txtServer.Text;
client.Port = 25;
try
{
client.Send(mesasge);
}
catch (Exception ex)
{
txtResponse.Text = ex.Message;
}
}
As far as I can understand, this should be a matter of configuration rather than coding issues.

we are experiencing big difficulties in the configuration of ASP.Net state service and II7. The service seems not working correctly because when the application pools recycles the applicatio loose the session.If we try the same configuration in IIS6 it works correcly.What is the correct way to configure the aspnet session state service in iis7?
View 2 RepliesWe have an ASP.NET application deployed on 2 Application servers with load balancer server. It is using INPROC state management. The ADO.NET connection pooling is enabled with 50 as minimum connections and 100 maximum connections.
In Load testing (using load testing tool) when the application reaches to 50 users no more users can connect (login) to application the TPS reaches zero. No errors are logged in application log related to application or database. The sessions are working fine.
Currently, on our production IIS web farm, we host about 15 applications in a single App Pool (Default App Pool). There are two websites and about 13 virtual directories.A colleague has recommended that we change our IIS configuration so each application is a separate App Pool (with identical settings).
Is there any drawback or potential issues to doing this?Is it possible that ASP.NET applications could have been built with the requirements that they are all within the same App Pool?
I know that ASP.NET MVC has error filter attribute to handle specified error type. However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to "Application_Error" method for handling this error like the following code.
public void Application_Error(object sender, EventArgs e)
{// At this point we have information about the error
var ctx = HttpContext.Current;
var exception = ctx.Server.GetLastError();

Apologies if this seems obvious, but after a week searching I can't find a clear answer to my problem.
I have developed an application in Visual Web Developer 2010 Express that uses the asp.net application services membership provider. It works well in development on my machine (data in the ASPNETDB.MDF database).
I packaged my application and deployed the relevant files with FTP to my shared hosting provider.
I took a copy of the ASPNETDB.MDF and restored it to the SQL Server 2008 on my shared hosting. I can connect to this through the Database Explorer in Visual Web Developer, but it doesn't contain any schema or data.
I know once I have the database in production I will have to make sure the connection string in web.config is poiting to it, but I don't know how to get the DB to production in the first place.
I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

I made one application which consumes WCF service and also using nettcp protocal. As we know, WCF application requires .Net3.0 and .Net 3.5 framework. but we have some dealer machine which are having window server 2000 OS now i am not able to install .net 3.5 framework on dealer machine . So we are not able to upgrade old application with new application which are totally based on WCF framework .
View 1 RepliesWe have an ASP.NET 3.5 Web application in which we have faced the below issue:
The application is working fine but suddently at one point application URL prompts for the authentication. When we (the support team) checked the server, we were able to identify that the access was denied for some of the main files (like web.config, default page). When we enabled the access the application started working fine.
I am getting the error from ur sample codeError validating application. Invalid application ID.",
"type": "OAuthException",
"code": 101
though i have added app domain name as "localhost.com"and site url as "Http//localhost.com:port_Number"/.
I have to implement broker and dealer socket connection like in share market i.e. it should connect at 9 AM and stop at 3.30 PM and repeat in next morning ...
so following is my requirement
1) i have to create application object once in day at 9 AM and destroyed at particular end day 3.30 PM.
My question is how to destroyed application object at given particular time ... i think this can be done in application_end handler in global.asax ... but my question is when no request is made at that time then what happened..
Question: I created an ASP.NET web application. Now it originally was meant for deployment on a webserver.
That is working, so, so far so good. My question now is: Is it possible to deploy it as a desktop-application, too? That is to say the installer installs some kind of server, plus the web application, configures the server to run this application on a localhost URL, and then creates a link in the start menu/desktop, where it opens that url (website, the application) on localhost in a web browser?
I think it should be possible, though the server wouldn't be IIS, because this is a windows component which can't be separately installed. Is there anything like this already out there? The nonplusultra would be that it only starts the server when you click on the shortcut.
