Can Use SQL Server Session State With Sessions That Contain DataTables

Feb 2, 2011

I have inherited an ASP.NET 3.5 application that relies heavily on sessions and storing DataTables within them (I know - bad, bad, bad). The application pool on the remote shared hosting service indicated that memory is at full capacity and as a result customers are losing their shopping carts because of dropped sessions.

Ultimately the goal is to rewrite this code, but for the time being I would like to stabilize the site the best I can. The host has recommended I use SQL Server Session State instead of in-proc. I have no experience with this, so I'm hoping it's as simple as running the .sql against the database to configure SQL Server and updating the web.config.

Working With Static Variables / Store The User Specific Information In Static Variables?

Mar 5, 2011

whats the exact use of static variables in overall programming in .net and for asp.net...

Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..

whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.

Web Forms :: Post Data To External Page And Set Session Variables

Aug 17, 2010

I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.

Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.

This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.

Passing Session DataTables To A User Control Simply To Initialize Them?

Jul 30, 2010

I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.

To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.

But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.

This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.

Keeping A Large Volume Of Data In Session?

Mar 23, 2010

I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance.

So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits.

If the user then looks at their contacts again the data will just come from the local DataTable.

Storing Large Amounts Of Session Data?

Feb 16, 2010

Im 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)

Pdf - Maximum Amount Of Data Stored In Session Variables?

Jan 11, 2011

I have a form where users can upload Pdf files(about 30 pages to one document or so). I want to delay storing these Pdfs in the database until the user submits the entire form. The problem is that the collection of files uploaded must be able to persist through postbacks. That being said, I am considering storing these as session variables, however, would this be too much data to store, or are session variables meant to store a couple strings here and there? If this method is not acceptable, is there an alternate method?

ADO.NET :: Creating An Entity Data Model Filtered On A Session Variables (C#)

Nov 1, 2010

I'm trying to customize correct displaying of dropdownlists so information shown in comboboxes is relevant to the kind of user logged on (maintaining referential integrity at data level)

e.g.: I have a user already logged on and depending on his profile I'd like to display to this user only the portion of the database that he would be allowed to see. That would mean that he might have acces to an specific subset of data, e.g.: businesstype = "3", loging level = "2", etc.

Is there a way of creating an Ado.Net Entity Data Model filtered on a Session variables as to maintain proper referential integrity at data level?

IIS InProc Session Variables Randomly Not Written To Session

Nov 12, 2010

There 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.

C# - Where To Store Sensitive Variables

Apr 4, 2011

This is my first time working on a secure website. It's for a pet project I have.

For security purposes, where is it best to store information like SQL connection strings, database encryption keys, etc? Is it better to use web.config, store them in a class that accesses a database (like dataBaseHelper.cs or something), or somewhere else?

I intend to obtain an SSL cert as well. When communicating with the database, should I always use the secure connection?
