Share Session State Between Two WCF Different Services?
Mar 16, 2010
I have two WCF services configured with ASP.NET compatible mode to allow them to use ASP.NET session state. The problem is as follows:
1.- A call to the first service stores a value in the ASP.NET session state.
2.- A second call to the first service can read that value.
3.- A call to the second service can't read the ASP.NET session state value.
It seems that the ASP.NET session state is not shared between the two WCF services. Is there a way to share ASP.NET Session state between two WCF Services?
We are migrating an ASP Classic website over to ASP.Net. One of the big hurdles is the large amount of data stored in SessionState by the ASP Classic website.
I am looking for ways that session state can be shared between the two applications. I found the following link from microsoft MSDN that describes how to share session with a shared database. Unfortunately it uses the binary formatter to serialize into the database and I have recently had some bad experiences with said binary serialization.
how to share session state? or alternatives to the binary serialization?
I am using cookieless session manangement in ASP.NET 1.1. When the session is active and the user uses the same url in a new browser window or a new browser in different machine. since the session is active the url will validate itself. When user open new window with same session, i want show some custom meesage.
I have two exactly the same web sites hosted in two different machines under IIS 7.5. ASP.NET state service is running on my machine and the web.config is updated in both sites with the following code:
The allow remote connection is set to 1 in registry in order for the second web site to access the state server.Both web sites have the same machine key:
Additionally both sites are configured in IIS to have the same Identifier.What I want to do is that both these sites share the same session data for example being able to do the following:
// At web site 1: Session["key"] = "value"[code]....
The problem is that I can't manage to accomplish this test and really can't understand what I am doing wrong.
I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution
public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; }
public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } }
I have 2 different Virtual Directories on my local IIS 7.0 server. I want to do session Management in such a way that Session variable created in one Virtual Directory is easily available in another Virtual Directory. I want to achieve this using SQL Server 2005. Till now I have done the following things
1) In my web.config file I have added the following entry
I'm having trouble getting 2 identical ASP.NET MVC applications to share the same Session using a Session StateServer. The reason I'm trying to do this is we will eventually be deploying this app across 3 web servers that need to share the same state. We need to use StateServer because we are trying to minimise use of the db for non data-related storage.
The Setup: I've deployed the same code base to http://localhost/App1 and http://localhost/App2
both have identical Web.Config files with the following:
The Result:For both deployments, when the page first loads I can see that the mode is StateServer and the timestamp is getting set to the same time as the realtime value.. However, if this was working, only the first page should have the same time as the realtime value. The second page load should read from the StateServer because that timestamp value is no longer null, and display that time value. But instead, it's displaying the realtime value again.
When I refresh the page, I the timestamp stays the same and the realtime value is always updating. This indicates that the timestamp is being saved to the Session, but the time stamp value is always different for both deployments when it should be the same, so this indicates that the Session is not being shared.
I want to ensure a user isn't editing the same form data in two different browser tabs or windows (of the same web browser instance). The intention is to stop the user from accidentally overwriting their own data as they continue through a very long form process. On the server, ongoing data input through the screens is collected into the Session.
Assume for any browser, all tabs and windows run in the same instance of it (i.e. not each in a separate process). Obviously the browser tabs and windows share the same cookies in this scenario so cookie modification seems out of the question for viable solutions. This is also the reason they are sharing the same session state.
Considering that the form is already created and this is one of the final touches, how can I use ASP.NET, hopefully easily, to oversee this "feature"?
Have not run the ASP.NET Development Server for a while. Today I copied a production website to my workstation and ran it with VS 2008. The following error message popped up. What is the problem with the ASP.NET development Server on my workstation? The website on the Production server still ran okay.Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection. If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name.
I read the solutioin for this error, at the following link :http://forums.asp.net/p/1046935/1576341.aspxbut I am still not clear what exactly causes the error. I have two doubts :1. Can anyone please elaborate a bit on this issue, with any example ????2. Is there any drawback of this approach ?
In ASP.NET, I'm a bit confused about role of cookies in session state. Whats is the difference between normal session state and cookieless session state?
I want to use a global data for MVC web application running on Windows Azure (e.g. something like a list of users having new messages).
For a normal webapp, I could use some per-appdomain storage like AppDomain.SetData or just static variable. What should I use for Azure instead (cache? blob storage? queues?) and what solution would be the fastest one?
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 created two websites ,such as [URL] and [URL]; The two websites both use SQL Sever Session Mode and they use the same database for sessionstate management.
in [URL],I have a controller as below:
public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Welcome to A Site!"; Session["User"] = 123; return View(); } }
[URL] I have a controller as below:
public class HomeController : Controller { public ActionResult Index() { if (Session["User"] != null) { ViewBag.Message = "Welcome to B Site!" + Session["User"].ToString(); return View(); } else { ViewBag.Message = "Welcome to B Site!" ; return View(); } } }
if I access [URL] first ,then access [URL], I will get the response :Welcome to B Site!123 if I access [URL] first,then access [URL] then access [URL],I will get the response:Welcome to B Site.
I have a problem with all multiple tab browsers due to session object. I have a requirement that whenever user opens a new browser I need to show different values, so I thought of using Session as in IE 6 every browser creates a new session. But all other multiple tab browsers IE 8 and FF shares the session(If user has already open the browser and try to open different browser). How can I create new session whenever user opens a new browser window. My application is basically in ASP.NET and server side we have C#.
I have problem in maintaining the application objects in the server when it is deployed in the web farm.In our application i'm storing the sessionID and and the column value ( "tvktnx55vl5mzr453dmaehit " + "A101" ) in arraylist and storing it in application object. when i test this it is ok. but when we deploy it we have one issue that is we cannot share the application object in web farm.
In my website I am maintaining log of users in which I am storing some user's information such as user machine IP umber,SessionId,UserName etc.and able to show the list of current and past users in webpage. I want to share and connect to browser session of any of the current users. Is it possible,if yes then how?
I have hosted my web forms files and reports files two different IIS instance in same server. When user login i keep username inside session variable. According to that session variable i checking roles each web forms page load event. i share session variable between two difereent IIS instance in same server?
Requirements: Create a Web Page in ASPx that will do the following:
1)One label will provide a count of how many times Button 1 has been clicked in the current session.
2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I checked the stack trace and its complaining about
I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.
