how to maintain session for multi user application

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :ASP.Net

I am developing a web application. This application is fully customised based on the user settings. Suppose, application hosted on www.abc.com and user can signup on the website and it will get the domain like www.user1.abc.com and for user2 will be www.user2.abc.com so and so forth. so in this case how would I maintain the session for each user?

each user will be representing a single website along with public interface and admin pages. 

what I am thinking is to store all the setting (for each user) in the database and then when ever server received request then get the user info from the URL (first time only and after get it from the session) and get user details but I am not very much satisfied with this approach. 

could anyone recommend me any better way to perform this task please?

ASP.NET: Nine Options for Managing Persistent User State in Your ASP.NET Application


ASP.NET provides many different ways to persist data between user requests. You can use the Application object, cookies, hidden fields, the Session or Cache objects, and lots of other methods. Deciding when to use each of these can sometimes be difficult. This article will introduce the aforementioned techniques and present some guidelines on when to use them. Although many of these techniques existed in classic ASP, best practices for when to use them have changed with the introduction of the .NET Framework. To persist data in ASP.NET, you'll have to adjust what you learned previously about handling state in ASP.

Share Point Designer 2007 Workflow (Sequential) - multi-collect data from user

I am currently building a multi-step workflow using ShrePoint designer for MOSS2007. I am getting a bit confused as to if I have an error or if I am doing something incorrect. Here is what I have going. My workflow consists of something similar to the following New document comes in, a collect data from user routine is ran and assigned to a reviewer. My understanding when I create a collect data from user WorkFlow step is any data I request is saved in the "Tasks" list. Therefore I need to grab the workflow task ID in order to later lookup what the reviewer submitted... I understand this...   However, I have one more collect data from user workflow step and I have one more item to collect. Even though this is a brand new collect data from user workflow step - does the collected data still go into the "Tasks" list? In other words, if I have two steps in a workflow and both of these steps are "collect data from user", does the data from both steps go into the same "Tasks" list?  I could see how this might be possible as long as the Task list columns contain all the items for all the different "collect" data from user steps.  I don't see two different Tasks lists representing or named "Reviewer" or "Final" or anything, so I assume the items are all in "Tasks"   However..

User Profiles Service Application and Import of SharePoint 2007 SSP data

I have setup a test SharePoint 2010 Farm. I will be using this as a test upgrade of a current live SharePoint 2007 Farm. The database attach method will be used. I have replicated the web application and AAM settings of the SharePoint 2007 Farm to the SharePoint 2010 Farm and have made the 2010 Farm a DC in a new Forest. I don't want to join this to the current domain at the moment. It also has SQL server 2005 with SP3 and cumulative update 3 installed. I have just setup the User Profiles Serice Application and when I go to Manage it, I get this. Error An unexpected error has occurred.   Troubleshoot issues with Microsoft SharePoint Foundation. Correlation ID: a1760e87-372f-4711-afac-3ceba34bc599 Date and Time: 8/31/2010 4:22:56 PM I have verified and configured the following. Created the Managed Metadata Service. The status is started via Service Applications and Services on Server. Created the User Profiles Service Application and ensured status is started via Service Applications. I started the User Profile Service and User Profile Synchronisation Service via Manage Services on Server.      

User Profile Application Failing in SharePoint 2010 (14.0.4514.1004)

I keep getting the following error "This User Profile Application's connection is currently not available. The Application Pool or User Profile Service may not have been started. Please contact your administrator.". As sugested by Travis at http://blogs.pointbridge.com/Blogs/nielsen_travis/pages/default.aspx I tried commenting the two security nodes, removing its' allowInsecureTransport attributes, and setting then False. As Lionel wrote in his comment I tried also modifying "Central Administration / Application Management / Configure service application associations / Application Proxy Group" of my share point web application. My application pool for User Profile Service Application seems working and User Profile Service status is Started.One thing I remember about my issue, first I tried creating User Profile Service Application I got some error message and tried creating User Profile Service Application again. It gave me some other exception and than I navigated somehow to the "Manage service applications" page and there the desired User Profile Service Application was magically on the list with status Started. I thought - that's great! But when I clicked the User Profile Service Application link I got the nasty red error I mentioned at the beginning. Any ideas?Regards,Dawid Ireno

Accessing Session State in a User Control

We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control? If so, how? If not, any suggested solutions? Thanks in advance for any help.

Questions on Multi-Tenant Data Architecture for SQL Server Database and ASP.NET application

My company wants me to make the same asp.net application and sql server database be sharable amongst different clients. Clients will use the database for their own business use, will have their own data, we will have our own data. How can I share the same SQL Server database amongst different clients having same ASP.NET application (but somehow be able to differentiate which client user is logging in) ? Do I need to use ApplicationID and how will I detect at login which one to use ? I know I will need to add another field in all tables to differentiate client's data from ours.
