Hello, We're trying to find a way to change the sessionState's sqlConnectionString (in SQLServer mode) at runtime. We're implementing a fail over for our SQL server and we want to catch when the sessionState fails to have access to my SQL server and tell it to fail over to my secondary server and initialize the site-wide fail over at th...
Hi people. I want to be able to log when a user ends their session on our application and record whether it was a sign out or a the session expired. I am using cookies.Add(new HttpCookie("ASP.NET_SessionId", "")); to set a new sessionId on sign out, but when the session expires, the sessionId is reused if the browser instance is no...
Per a question I posted yesterday, our website's DNS structure has changed to round-robin DNS which literally swaps back and and forth between two production servers. Our web.config for both prod servers has: <sessionState mode="SQLServer" ... > pointing to the same shared DB A machineKey on each server that is consistent between the t...
I am rather new to MVC applications, and one thing I am trying to accomplish is enabling or disabling stylesheets based on a Session value. I have stylesheets referenced in my Site.Master page in this manner: <%=Html.Stylesheet("~/styles/main.css", "string")%> <%=Html.Stylesheet("~/styles/additions.css", "string")%> Right now, for tes...

I have a user complaining about frequent timeouts in my Intranet web page. While looking for a solution I found this post: http://forums.asp.net/t/152925.aspx?PageIndex=1 Where a poster recommends intercepting the redirect to the login page, submit the data to the database, then either reauthorize the user (without their knowledge) or...

Server-side sessions are not [yet] part of the Snap Framework. Is there a way to add some sort of server side state? Let's pretend I want to increment a counter for each HTTP request. How would I do it? ...

Is there a difference between Session.Clear() and Session.RemoveAll()? The descriptions and documentation pages seem to say exactly the same thing, but I am assuming there must be some reason for creating two functions, right? Thanks. ...
Hello, I am facing a very strange issue. I get an error Object Reference Not set to instance of object on the server while the code runs fine on my dev machine.

Hello All, I am in dire need of a better way to handle sessions. We currently use default in-proc (IIS Worker Process) for our ASP.NET MVC web apps. I am now trying to implement ASP.NET State Service locally on the web server. I have installed and enabled the service (also set it up to start automatically). I believe that we're succ...

We have an ASP.NET web site that uses SQL Server session state. The state is configured in Web.config like: <sessionState mode="SQLServer" sqlConnectionString="data source=TheServer; User ID=TheUser;password=ThePassword;" cookieless="false" timeout="480"/> But there are three environments (development / staging / production). Al...

The basic design is that a typed dataset is loaded from the database and stored in session state using a common session variable name like Session...
I'm having some trouble with users losing session data whilst going through an application form. It appears that they're losing session state part way through application forms. (ASP.NET 4.0 WebForms project, IIS 6.0) Session is stored out-of-process in the state server so it's not config changes, appdomain recycling, etc AFAIK. <sessi...

I predict that the reason of such behavior are some exceptions thrown and unhandled in side threads of application or whole application restart. I'm pretty sure that it's not caused by recycle worker, because it happens in irregular peri...
