We are going develop a web application using asp.net. This applicaton is going to server 50 users per day and 40 users concurrently. As the user count is less, we are planning to have two webservers clustered under a webfarm. We are planning to go for a Sticky Session. Netscaler is the load balancing and reverse proxy we are using at hardware level to route to the same webserver till the end of the client session.
1. Do I need to implement any handler at asp.net level to route the session or to provide browser cookie details of session to NetScaler? If so, what should be implemented in detail. Any sample code will also be helpful.
2. I need to maintain a big chunk of object information in session. Does a webserver can handle it?
3. At the hardware level how ReverseProxy works to navigate it to the same webserver? I want conceptual details of it from a web application end.

I am a problem in my one of my web applications. I run this application under ASP.NET Development Server. Normally, in all of my other projects, when I made a change, I recompiled the project, and then press CTRL+F5 in the browser, then the new changes will be displayed in the browser. However, this specific project, when I made a change, recompiled, and then press CTRL+F5 in the browser, the page stayed the same as it was, withouth displaying the changes. I have to restart the ASP.NET Development Server to see the new changes.
This problem is not only happending in my PC, but also in others who doesn't have Visual Studio installed. So I guess there is nothing to do with my PC's environment. Are there anything wrong with my web.config?
I'm running an ASP.NET ver 4.0 website on Windows Server 2003. Everything was working fine, until I uploaded a new version of the site tonight.I have a new version of the website on my local box, with so many changes that I decided to remove all the existing files on the live site, with the exception of the web.config.Then I uploaded all new files (except the local version of my web.config) from my local box to the live site.
Afterward, when I browsed to the site and tried to use the standard Account/Login.aspx page, all my server code in the code-behind file was displayed in the browser!What would cause this? It *seems* like that would be a server-configured issue, but after I rolled the website back to the old files, everything worked again!
I am getting this error on a website. does that mean the server is not competible with asp.net 3.5

i created area "Decoration" for dynamically generating images.
public ActionResult Round(CornerPosition x, CornerPosition y, int radius, string color, int width) { Color c = ColorTranslator.FromHtml(color); Pen pen = new Pen(c, width); MemoryStream s = new MemoryStream(); using (Bitmap bmp = new Bitmap(radius, radius)) using (Graphics g = Graphics.FromImage(bmp)) { g.SmoothingMode = SmoothingMode.HighQuality; g.Clear(Color.Transparent);
when i reference image on the page <img src="/Decoration/Corner/Round/Right/Top/8/Black/1" /> it displayed properly if started in VS 2010 debugger.
but as soon as publish web site image not displayed!
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.
We have lot of application parameters for each module in a C# .NET 4 ASP website. parameter examples: timeouts, formulae constants, thread limits per module, $ charges per usage etc. What is best out of following approaches we know: Use DB config table Use an xml. load that xml into local cache on start (and on xml change) simple constants.cs file with public const int XYZ = 123; type of key-value pairs. web.config (though i think its mostly for deployment type of config)
I have a web.config file defined in my asp.net web application. I have many different settings configured there. I have another project, this time a console application. I'd like to read several configurations from my web.config file. How can this be done?
I have an application which has a website and a project. The project contains an executable file which I'm trying to run as a process from the website's Global.asax file's application_start(). When I run this application from localhost, everything runs smoothly but when I deploy the application on IIS, application_start's code is executed and I can see the process name in the taskmanager but I cannot see the window which the console application normally starts in (when i run the application on localhost) and neither is the code executed.
Here's what I'm doing:
-- copied website and project in wwwroot -- made a virtual directory of the website -- when i run the website, I see the process in taskmanager but the code is not executed.
I am new to deployment and IIS, and would really appreciate I someone could tell me what i'm missing
Excuse me this common error. I´ve found a lot of info in Google but I´ve not found my error. I´m trying to read some data from a custom section in web.config and I don´t know which is my error?
