How To Maintain Session Information Between Two Calls Programmatically
Mar 17, 2010
We have an external site which the users in our company connect to by giving their corresponding username and password. The external site is an ASP.NET website. We want to integrate this website into our intranet portal so that the users don't have to enter their UN/Pwd to login to the website. Since the target website has no provision for SSO, we are simulating the POST request to login.We are now required to perform an action after the initial login is done, on an another page. We can simulate the corresponding POST request as well

I am trying to retrieve SessionItemShory column for given sessionid.The data stored is serialized so we need to deserialize the data to use it.I am trying to do that but its not working.

public string country { get; set; }
public string city { get; set; }

This is quite straight forward. I'm calling a web-service (.asmx, with session enabled) from a c# application. I want each call to be with the same session key as the previous one (as opposed to creating a new session key each time).
Here's my (nothing-out-of-the-ordinary) code:

I'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.

I am running an ASP.Net page on IIS7, and developing in VS 2008. Currently, I have user authentication being done through an LDAP connection. Once the user logs in, on one page they have a form with some basic information about them (such as their name, email address, country, and the like) and I wish to pre populate some of these fields from information already stored in the LDAP. In particular their given name and email addresses. The question is, using C#, how do I actually retrieve this information?

The Situation: When there multiple PageMethod calls in a single page, each of the method call holds a lock on the Session object thus blocking. The PageMethod calls can be made asynchronous only with @Page directive is turned to False|ReadOnly
Findings: When the Page directive is default (read/write) but the session is not used anywhere on the page, the calls are not blocked. Any read or write in to the session at the page level blocks the pagemethod calls.
The Problem: Making EnableSessionState=ReadOnly at the @Page directive is very restrictive and don't want to take that route. Can the pagemethod calls not block? and still access the session? (may be not write but just read)

I've inherited an asp.net web solution, which has business logic and data calls as seperate assemblies. In the business layer there are a small number of calls to get/set HttpContext session values. I've looked around for an example that will allow me to abstract this away from the business logic as I'd like to be able to reuse these assemblies in non-web projects, could anyone please give me an example of the best way to do this. I was thinking of some sort of session factory that will obtain values from some sort of persistant store depending on the usage scenario but I'm new to architecture really and would appreciate a pointer or two.

I'm working on a project for a large company that wants to create a crypto toolbox for cross-platform signing and encrypting and am constantly running into problems concerning the cryptographic abilities in the .Net framework. The blazing inferno that I need to put out this time is that SignedCms and EnvelopedCms don't seem to work with a Cryptographic Service Provider that doesn't store the private-key on the Windows machine. I'm working with a network HSM and certicates that have only a public key, that is, no private-key and no information in the store as to where that private-key resides or how you can access it (a RSA public/private key pair is created on the machine, using the HSM supplier's CSP, and a certificate signing request is generated and used to create a public-key certificate signed by the CA). Theoretically the private key gets picked up from the HSM (referenced actually) using the CspParameters given when instantiating the class, which specifies the CSP provided by the HSM supplier. Unfortunately, up to now this only works with CAPI, where can associate the cryptographic service provider with the signing certificate (usign CertSetCertificateContextProperty with CERT_KEY_PROV_HANDLE_PROP_ID). (We're using CAPI for PKCS#7 signing because the .Net framework only supports signatures up to SHA1 and we have a minimum of SHA256). Surprisingly enough CmsSigner accepts a CSP in it's constructor but it cannot get the key, it throws an exception during instantiation from method CreateDummyCertificate for some reason (with the message "Process completed." no less!??). I use the following CspParameters:
[Code]....
CmsSigner cmsSigner = new CmsSigner(cspParams);
This process works great with certificates and key pairs created by MakeCert. With MakeCert you can associate the CSP information with the Certificate upon creation (-sk, -sp, -sy). The private key still resides in the HSM but specifying the provider during the creation of the certificate seems to have persisted the CSP information somewhere, somehow. Exactly how that's done I don't know, but if could do that, my problem would be solved.

If a normal session timeout occurs we could handle the session timeout.
But say we are using a lot of ajax calls, webhandlers etc. How would we catch session timeout here and redirect to error/login page.

how can i do this? At the moment a user's session is lost whenever they close the browser, but sites like facebook have a 'keep me logged in' option. How does this work exactly and are there any well known ways to do this in .net? i understand part of the way it works is that they store the username in a cookie.

I'd like to maintain a session state per browser tab.
Is this easy (or even possible) to do in ASP.NET?
Example: A user hits Ctrl-T in firefox 5 times and visits the site in each tab. I'd like each tab to have its own session state on the server

I have two identical applications setup on IIS on different virtual directories (I have done some workaround to ensure that they both have the same application name). Is there a way to share session id across two asp.net web applications?
Since I'm storing the session in StateServer, they should both be getting the same session data, however, a different session id is created everytime I go from application a to applicatino b. Wouldn't this happen in a load balancing scenario as well? Where when I go to www.test.com, it would redirect that request to server a, and then if I hit it again, it would go to server b, but since it's a different web application, it would create a new session id?

If I have a 2 control load events and one page load event subs and the control1_Load events fires first, can I lookup some database things and persist them? I would like to use the persisted data in the other two events when they fire. Normally I've been using session variables , is there a better way?

What is the standard way to maintain a stable user session in ASP.NET without worrying about IIS recycles, disconnected users, re-opening browsers and so on. I would like for our users to not have to login except once per month, whatever happens!
Also does it matter if I am using my own login control (not the standard asp.net login control)? If I understand correctly, I think I would need to create an authentication ticket manually.

I have a requirement where i need to download mutiple files as a single zip file.There is linkbutton named HOME as well in the page. when this linkbutton is clicked it should redirect to homepage.aspx. I found a ICSharpCode.SharpZipLib.dll in net and used in my website. Here is the code
[Code]....
With the above code i got the expected result i,e. i can zip the files and save on client system. But the problem is after saving/canceling the zip file if user clicks on linkbutton in the page_load event Session[getdata] became null. there is no data in Session. what might be the problem? Actually it should redirect to homepage.aspx but its going to login.aspx because Session[getdata] is null.

I am developing a web application. This application is fully customised based on the user settings. Suppose, application hosted on [URL] and user can signup on the website and it will get the domain like [URL] and for user2 will be [URL] 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.

I am using master page.
(1) to maintain the state of the treeview without storing it in session or view state or
(2) I am binding the treeview control dynamically from a xml. Even if I use session state is ther any option to use it without using SelectedNodeChanged event because when u click the treeview node , first master page will postback for this event and then the child page and then again the master page will post pack (as the child page has inherited the master page). So here in this case we are posting the master page twice and it is reducing the performance.
