How To Retain The Value Of The Session In Web Service
Jul 24, 2010
i have created a web service that will we accessible to only authenticated user of the website.when user first time call a web method first he will we authenticated.when authentication is successfull i will create a session for that user.now on next call to the web service by that user i want to use that session means he is authenticated user.But on the next call session becomes null .what is the problem with that.
How to retain the value of the session in web service
A web service using ASP.Net web service The web service has a web method with EnableSession=true A client which refers to the web service using "Service References" (note: not "Web References") The app.config of the client has allowCookies=true
[Code].....
The call to AppendUpload returns false, because of the mismatching session ids. Why is that? As far as I can see, I have the right attributes for the web method, the client has the correct config, and the same instance of the proxy is used.
We are setting session variables in the login page with all user details.And in all subsequent pages we check this session variable.This check is done in the page load of master page.As the number of users increased am getting error with these session variables.This session variable is returning me "nothing" when I check and the user is redirected to logout page.Interesting thing is that this is not happening always.
I have an ASMX webservice hosted alongside my ASP.NET web app. Now, I need to get the users session into the Webservice. To test this I made this simple method:
[WebMethod(EnableSession = true)] public string checkSession() { return HttpContext.Current.Session["userid"].ToString(); }
So, first I login to my web app, then in the browser goto my webservice and click "checkSession" on that auto generated test page. I have tested this on 3 computers. All 3 of those work fine with the webapp(so the sessions are being created etc), and 2 of those return the value of Session["userid"] on invoking the webmethod, however the last computer returns "Object reference not set to an instance of an object" because Session is null.
So, whats the difference between these computers and why can my ASP.NET app get the sessions on all computers but the webservice cant?
Im using asp.net website with WCF service, having wsHttpBinding,Aspnet compatibility enabled, specified as Sessionmode -allowed, service behavior- isinitiated and client session cookie enabled. Its looking like Asp.Net session object and WCF Session( HTTPContext.Current.Session) work independently. How can I share Asp.net Session value to WCF Session and vise versa.
I have a web site that streams on demand video content. The video content is stored and delivered from a seperate SMD platform. My website submits a url request to the media server in order to get the media to display. My user session data is held in a sql server database on another seperate server.
I think the best way for me to do this is to create a web service that can validate a session id. So when I create the url on my web site I include the encrypted session id. The media server then sends this encrypted token to my web service which in turns decrypts the token and validates the session id against my database and then returns whether valid or not which is used to check if the content can be displayed.
on click of logout button, i want to call a web service method that will get that particular user's session and call its abandon method. But how can i pass that session variable to that web method ?
Calling of web method is done through java script.
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).
I'm finishing up my first web service. It stores data on a dataset that I later need to check up on, so I need to keep that information around. I've already enabled the session in the web service's method "EnableSession = true" [WebMethod(Description = "Receives status requests, as well as status udpates.", EnableSession = true)]
If I debug the web service everything works but if I try to use the application that sends the requests to the web service while it is published, the session keeps restarting again and again and again.
I have a number saved in session and am using it in a bunch of pages right now, and I was wondering if I could somehow access this session in my WebService.asmx file? It would be great since then that way I can fix my auto complete extender. I know I can use contextKey, but I am using that contextKey for something else. If session isn't possible in web service, then is it possible to use two contextkeys in auto complete extender, and how?
In my ASP.net website we are going to use Silverlight to display some interactive diagrams. The users can add, edit and delete various diagrams on the silverlight front end. Silverlight will call Web Service methods to save the changes into the database. Besides the data being passed by silverlight to web service call, we also need to pass some data from the session (like logged on user id etc.) to the web service call.
My question is that how silverlight can access session data? I am trying to pass session information via a webservice method call over to Silverlight but, the session variables inside the web service methods are returning null value.
The Web Service is running under the same web root where the ASP.net website using Silverlight is also hosted. I have made EnableSession = True for web properties.
I'm working on an ASP.NET MVC web application that will be deployed across multiple load-balanced servers. With this setup, a user might have one request served by server A and the next request will be served by ServerB or ServerC. We don't want to store Session Data in the database, as we're trying to minimise database hits where ever possible. As such, we need to have the HttpSession managed and stored on another server. My understanding is that this is possible by using a Windows Service that will manage this for me, but I'm unfamiliar with how to implement this. Can somebody point me at some good documentation on how to do this? Or any pitfalls or other points to take into consideration?
I have several ASP.NET sites, hosted on the same domain (different subdomains) and working via HTTPS. I have WCF service, hosted on the same domain. I have a separate state server for sessions.
All sites use cookieless session (if someone asks why - i will reply later, but it's a 'must')
On my sites, I use grid components from Telerik (but actually it does not matter) that ask for data from WCF service and must be filled with this data.
The problems are:
1) I cannot manage to make POST request to WCF service from javascript: for some reason it's always either GET or OPTIONS (no matter if I use Sys.Net.WebServiceProxy invoke or just a plain jquery AJAX request). It happens even if I indicate COOKIE mode, not cookieless. Maybe because of this I am getting "405 Method not allowed" error - WCF is set for POST request, but the site sends GET...
2) I cannot manage to retrieve SESSION from my websites! I tried approach, that I found, but WCF always uses OWN session, instead of 'connecting' to existing ASP.NET session, despite on ASP.NET compatibility mode. I need SESSION to exchange data between my sites and WCF service
3) I don't have idea currently, how to manage security when exchanging data between mentioned ones, in the light of above-mentioned problems...
4) I don't know exactly, how web.config for WCF service should look like in my case, because I've seen tons of different variants, but all for some simple cases.
Would be really appreciated for the help! I'm stuck for 2 or 3 weeks already, far behind the plan, but nothing still works... I can see there are some pieces of info about similar problems, but I'm afraid to miss some small thing - in web.config or method attribute or IIS setting, etc - and f... up everything.
I'm using Session variables inside a web service to maintain state between successive method calls by an external application called QBWC. I set this up by decorating my web service methods with this attribute:
[WebMethod(EnableSession = true)]
I'm using the Session variable to store an instance of a custom object called QueueManager. The QueueManager has a property called ChangeQueue which looks like this:
I created an AutocompleteExtender web service. I am getting a Object reference not set error in the peice of the code where I am referring to System.Web.HttpContext.Current.Session. Does anyone know why this is. And I am checking to see if it is != null before I reference it. But it crashes. Is there another way to pass another parameter to the web service?
I have written code that uses a .bat file (code: rwvinstat /server:servername) that populates a DataGrid of users logged in to a terminal service session in c#. The .bat lives on the server with the app. files and will run properly if executed manually on the server .Also if i run the app. locally and call the .bat file on the server it works fine.
The problem is when i deploy my web app on the server the DataGrid never populates nor do i get any errors. i have given full permissions to IUSER_MACHINENAME(and various users) and i set the virtual directory permissions to read, run, execute. Ialso have set my web.conf fig to:< "identity impersonate="true" userName="username" password="password"/> Here is my Source code:

I have recently moved our ASP.NET session state from InProc to a Sql Server solution. I can see session data being inserted into the Sql Server database. I'm monitoring the w3wp.exe process using the "Private bytes" & "# Bytes in all heaps" performance counters.As I navigate through the website it places data into session, however the private bytes counter still climbs on the server hosting the website? I thought the session data was being written to the database and not being stored in memory? The managed bytes remain constant, and I'm pretty sure all the objects going into the session are managed types.
I have a module that subscribes to PreRequestHandlerExecute event, which uses the Session object. When i set the webconfig compilationdebug flag to false, the Session object is null when making requests to the web service. It works fine for .aspx requests, but only have problems for .asmx. When i set the debug flag to true everything works fine. I need to set this flag to false for production, but can't seem to get it work.I'm using II7 and the integrated pipeline, so this event will fire for all requests.
we are experiencing big difficulties in the configuration of ASP.Net state service and II7. The service seems not working correctly because when the application pools recycles the applicatio loose the session.If we try the same configuration in IIS6 it works correcly.What is the correct way to configure the aspnet session state service in iis7?
I have controls in the forms . After submit , I am displaying crystal report. After display of Crystal report if I come back to my form again using back button my values in the forms are not retained .(i.e) Some controls having values , some not and some have different values.

I have an IEnumerable< T> which is declared on the page like this:IEnumerable< Person> person;When the page postsback, the person list is null. How can I retain the values of person list without declaring it as static? Sr. devs in my company say that you should not declare the list as static.
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
Page is a typical search page with few filters on it. When search for records based on filters, it shows result in Gridview.

I am loosing selected filters values and no result in grid view.How can i display selected filters and its results in gridview when user is coming back on search page? Any example etc.?
