State Management :: Using Caching While Storing Variables?
Jun 1, 2010I've begun building a bit of a framework that I wouldnt mind working with. The idea is to create a framework that makes it even easier to create CMS addons (So basically a CMS framework).
One of my goals with this project, was having all modules made within the framework automatically support version without any extra coding.
More to the point, the way that I started building this, many pieces (Lots had to do with the versioning system) became interlinked. A version Object in the code related directly to a Module Object and vice versa, therefore the class definitions for each relate to eac otherh. (So having only the Module object, i could access the versioning object and all of its properties). My issue with this is of course what happens if i have both the module and versioning objects in my code simoultaneously, resulting in having not just duplicates of the data within the code, but (perhaps) infinite amounts, killing the app.
So what im wondering is, what if my modules properties where stored within the cache? Ie if i had the Module object, and it had the property ID -- Then the data for ID would be stored in the cache within the module object. Referencing the value simply retrieves the value from the cache if it exists there, and the SQL database if it doesnt. This way, all instances of the module that may be running at the same time will have access to the same information, at the same time, and hopefully causing it to use less space in total.
I would then add a function, so that if a developer was loading a rarely used module, or dident want to occupy cache space with large amounts of data, then they could just call a Dispose function that would remove the data from the cache.
Does this method sound reasonable? I know this probably isnt what the cache is designed for -- but I cant think of any other way to do this without having an infinite loop of objects referring to each other, or causing huge discrepencies from having different instances of objects referencing values that should be the same, but arent because they are technically different instances.

C# - Storing Classes In Session Variables - How It Works (memory)
Mar 31, 2011I've read that you can store classes directly into a session variable i.e.
Session["var"] = myclass;
My question is how the memory management works. Does it automatically serialize this into the session on the client side?
Or does it hold the data for the instance of the class in server memory, and just holds a reference in the session object?
Storing User Variables In Database Versus Session In C#
Jul 28, 2010I'm working with an asp.net application that stores most data in a database and not session. I'm wondering of the pros and cons of each and which is the better way to go. For example, you have a pretty busy site and instead of storing user specific variables in session, there is a DB table called user data and it can store all user specific data that can be accessed from any page by querying the database. Which is the better way to go, session or database?

Oct 11, 2010I use some session variables to get the job done(shopping cart, etc) but it is not stable..manytimes I get no items in session object and other times(refreshing the page) I get missing data...I downloaded the entire site code to my local pc and debugged it and run it succesfully without any session data missing...When I run it in the server, I get bad session again: no products in shopping cart or products with missing quantities...
The same website runs smoothly in our production server too....The problem is with our development server...
State Management :: Session Variables And Tabs / Is There A Way To Reset The Session Variable
Nov 11, 2010I have some code in my page load event where I just want to fire once when the user opens the Browser. The only issue is if you open a new tab with the same website the session variable does not reset. Is there a way to reset the session variable when you open a new tab or do you have to take the whole web browser down for it to clear the session variable.

IIS InProc Session Variables Randomly Not Written To Session
Nov 12, 2010There are reams of info out there about things causing InProc session to drop session objects, but that's not what's happening here. We're missing individual variables within stable InProc session objects, and are not sure whether they're not being written or being lost after a successful write. I've confirmed with WinDBG that the sessions are live and contain some, but not all, of the data written to them.
Guid g = System.Guid.NewGuid();
this.Context.Session.Add(g.ToString(), result.ImageData);
output.Write("<img src="display.aspx?id=" + g.ToString() + "">");
This code is pretty straightforward, and it works flawlessly in Test. In Production, under heavy load, though, it fails ~1% of the time. If Mr Smith visits the site and attempts to display 4 pieces of image data, 2 of them might be saved in his session and two of them be lost. The InProc session object for Mr. Smith exists. The traffic logs show he clicked 4 times, each with a different id param. But there are only 2 guids in his InProc session object, instead of 4. The 2 session objects we did capture do correspond to 2 of the id's shown in the traffic log (his 1st and 3rd clicks.) The traffic logs for his 2nd and 4th clicks, though, show a guid id that's not in his InProc session object.
Lines 1&3 of the above code obviously worked for those 2nd and 4th clicks, or he'd not have had the id in the URI for him to click. Line 2, however seems to have failed silently in some way. If any exception had been thrown, I'd expect we'd not ever have arrived at line 3. I can't see any way for the user to receive the guid id, but the session to fail to have it. The other possibility is line 2 worked successfully, but the variable later disappeared, how I cannot even imagine.

View 1 RepliesC# - Storing Dictionary In Session?
Jan 29, 2011How do you create a dictionary of objects in the session? More specifically, I have a list of objects: MyList stores MyObject as the result of a linq query with the date as a parameter.
List<MyObject> Mylist;
MyList = GetObjects(TheDate);
Now I'd like to store MyList in the session object in a dictionary with the date as the key. When the page needs a MyList for a specific date, first search the dictionary and if it's blank for that date, get the data from the GetObjects query and store the result in the dictionary in the session.
Caching Gridview Data In Session?
Jan 28, 2011I have a reporting page with a gridview and a calendar. When the user loads the page, the default date is today and when he clicks on a date in the calendar control, it loads the reporting data for that day. Each user has a different report and the data is between 300-500 rows per day. At the moment, I have a linq query that returns the data for a day in the form of a list. Given the relatively small amount of data per query, I'd like to store the result of the query in the session so that I can do the paging and sorting from the session, without going back to the data store.
What I'm looking to do is a list of lists so that when the query loads, the data is saved until the session times out. For instance, if the user selects 4-5 different dates, each of these queries is saved in the session and then if he clicks on one of those dates again, a function first checks to see if the data is in the session: GetQueryFromSession( DateTime TheDate). I'm stuck on this. How do you create a list of lists that works with the session object.
Storing User-id In Session Variable?
Aug 30, 2010When a use is logged in (Through open-id) we are creating a session variable named "UID" and storing the unique user-id in it. Later we are checking the session to see if the user is logged in. I think this is not the right way, but I could not force the team to change this, as I cannot show how this implementation can be cracked. why (If yes) this implementation is bad?
View 3 RepliesMVC :: Storing User Information In Session With AspNetMembershipProvider?
Jun 4, 2010i m developing an application in .NET mvc2. i m using aspnetMembershipProvider for User registration and related activities. i need some custom information about user that i stored in a separate table (sysUser for example) and linked it to aspnetUser table through foreign key. after Login i need to fetch user's credentials from sysUser table and push it to the session. For this Account controller's Logon method seemed best to me and i pasted following code in my Logon ActionResult
[Code]....
The code is working perfectly for me and put my desired information in the session but the thing is that if a user selects Remember me and on his next visit he won't have to Log in and i would not find my desired information in the Session. where should i put my code that stores the user information in the session.
Security :: Storing Profile Information Into Session
Feb 10, 2010I have created a custom user creation wizard to store custom user information, This is working fine. I am now trying to create a new page to give the newly created user to create users in there own company, so i need to retrieve the company information from the user profile created and automaticlly fill that information into the new create user wizard. ie User from A company logs in. (company_id from profile is stored in session)
User A wants to make another user in company A (but cannot make a user in company B) User A fills in details for new user, Company A information is autofill into new user info. (possibly from session)
I have read alot about storing membership. info into session but i cannot find any code examples of how to do this. I need to find a way to store Company_id into session and then use that for creating a new user with the same Company_id.

Jan 29, 2011I have this program in which I am trying to store a collection of values into a list and session
Example:
valueCollection = (List<Values>)Session["Value"];
I want to do the front end in a way which will show a table with each row showing a label and textbox. This would be too simple to do obviously but I want it to show 4 rows of the table by default and then the user can select "add another" this will then add another row onto the table with a label and textbox exactly similar to the 4 default. Everytime the user selects "add another" the table increments by 1.
Storing Large Amounts Of Session Data?
Feb 16, 2010Im in the process of developing a web application, and I wish to store a reasonable amount of data for each user.
This data will be accessed each time the page is refreshed.
The only 2 options that I have come up with is:
* Session Data
* Storing the information in a text file with random file names for each person
* Database
The first one I do not really want to use as it would bog down the server - the second one is cumbersome
Is there any other options?
If possible i was thinking using the database, but am hesitant because of the amount of times the accessing of the database would need (every refresh for every user)
I dont want to store the information inside the viewstate (i dont know what MS was thinking when they thought of viewstate)

Web Forms :: Storing Session Data Continuously?
Oct 20, 2010Is it possible to store gridview session data after each postback. I have a gridview and a checkbox within. Each time a user clicks the checkbox, I like to store the gridview ID in a session. After browsing through various pages, I like this session datato continuously store the information up to 20mins?
How can I continously store the session variable. Say a text box and if I enter 1 click on a hyperlink (where session variable is stored) return back to the page, enter 2 click hyperlink then I should get in the session 12?
Storing A Reference To The Parent Control In Session?
Aug 24, 2010I have an ASP.NET web form that has a "container" usercontrol that hosts several custom user controls on the page. The controls can be hosted directly in the container or can be children of other usercontrols. The container usercontrol has several public properties exposed that I sometimes need to get to from within the child user controls. I've been using some form of "this.Parent" or "this.Parent.Parent" to get back to the base control.
What would be the impact of storing a reference to "this" into Session from the base control so I can access it from within the event handlers within the user controls?

How To Make The ObjectDataSource Have Caching Unique Per User/session
May 24, 2010have an ObjectDataSource with the following configuration:
[Code]....
And the 'Select' parameters will aid in making a 'unique' combination per user selection to populate the GridView it is bound to:The problem that is occurring is that GridView search results are indeed cached, but the cache is a little too public and shared between all users currently running the application. So if user1 creates a search that populates the GridView with 100 results based on some unique dates and CategoryID, and then user2 in a separate browser does another search with different dates and a different category

View 10 RepliesVS 2010 - Storing Sensitive Information In A Session Variable?
Dec 17, 2010I am creating a website that allows users to login to their gameserver remotely and send / receive commands. The connection happens via an UDP socket and requires simply the IP of the gameserver, and a password.
On my website, users can add servers to their accounts, where the server IP and password are stored in a database. Then they can connect to any of their servers, which creates a new Socket object and connects to it using the IP and password of that server.
This Socket object, embedded in an object that also stores the server IP and password, is stored in a Session variable when the user connects, and is retrieved on every page. For example, there's a page where the user can view a list of the players on the server (and kick/ban them), a page with server settings, a page with messages, etc. All these pages require the Socket connection to get their information (they send a certain command and parse the response). When I need to send a command via the socket, I need to send the password of the server each time (otherwise it does not work). My question now is: how secure is this? The password of a server is sensitive information*, but I am storing it in a session variable and sending it (using the Send command of the Socket object) to the server.
i think the Session variable is stored on memory on the server, so I don't think so, but I'm really unsure about these kind of things and I'd like to be certain that my website is secure. Well, I think it will never be 100% secure but I want it to be at least not worth the effort for someone to hack the password. If it takes a lot of trouble then people wouldn't bother, but I don't want to find out that people's passwords are being thrown out on the street (so to speak) and that my website is completely insecure...
