C# - The Number Of Users Online And Number Of Active Session?

Mar 12, 2011

My environment is ASP.Net + IIS 7.0 + Windows Server 2008 + .Net 3.5. I am wondering whether the number of users online and number of active session are the same thing? The other question is, no matter whether they are the same, how to calculate them (i.e. for a given time, what is the number of users online, and related active number of sessions)?

Large Number Of Session_Start With Same Session Id?

Feb 9, 2010

I'm running a ASP.NET website on my development box (.NET 2.0 on Vista/IIS7).

The Session_Start method in global.asax.cs logs every call to a file (log4net).

The Session_End method also logs every call.

I'm using InProc session state, and set the session timeout to 5 mins (to avoid waiting for 20 mins).

I hit the website, wait for 5 minutes unit I see the Session_End logging. Then I F5 the website. The browsers still has the session cookie and sends it to the server. Session_Start is called and a new session is created using the same session id (btw: I need this to be the same session id, because it is used to store data in database).

Result:

Every time I hit F5 on a previously ended session, the Session_Start method is called.

When I open a different browser, the Session_Start method is called just once. Then after 5 minutes the Session_End each F5 causes the Session_Start method to execute.

Update:

After the Session timeout, all subsequent requests have a session start & session end. So in the end my question is: why are the sessions on these subsequent request closed immediatly?

MVC :: Large Number Methods In The Controller Vs A Case Statement

Feb 11, 2011

Working on a heavy ajax based site with over 100 methods from all the ajax calls inside each of each controller all with basically the same code.Was thinking of changing them to a big case statement for readability which would keep the code a bit more dry and make it easier to read.What I am wondering is: Will there be a performance hit and is there a better way to deal with it?

Architecture :: Serving A Large Amount Of Users On A Web Server?

Oct 5, 2010

I have a project that will be assigned to me soon whereby I need to develop a survey which needs to support 40,000 users approximately. Now we are thinking of doing a staged approach so not all users are on the server at any one point of time. Probably splitting it so we can serve at least a few thousand of users...

I dont have much experience of how I can ensure to serve those levels of users on a server and how to manage this so I am after some advice?

From my understanding I need to do some stress testing on a server and obviously I need some figures i.e. average size of request, average size of response and content of response.

- Do I have to build the database and add records in to see what size is a typical survey row?

- Do I have to build the survey in .NET i.e. by adding controls etc and seeing what size is the page?

- The survey shouldnt be too instensive processing wise, it will be adding information into a backend sql database...

VS 2010 - Presenting Large Number Of Records To User For Selection

Jul 24, 2014

I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.

Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.

I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.

My questions are these...

Is there a better way to handle this quantity of records than a stored proc and combobox? A

ny examples of a method to populate a certain number of records then filter based on user action?

C# - Administer Website (create New Users, Assign Users To Roles, Etc.) From A Windows App?

Feb 9, 2010

I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.

Here is the membership provider definition from web.config:

[code]....

So, obviously, I have a Sql Server database that contains the users and roles for the web app. I'd like to create a separate windows app that references the web app assembly, and use the configured MembershipProvider, RoleProvider, and machineKey to create users, assign users to roles, etc. If that's not possible, I can duplicate the configuration settings from web.config within the windows app. But I don't know how to do this either.
