  • How to generate custom JSESSIONID, based on some hash of user's data?

    - by Shaman
    Is it possible to override Tomcat's embedded generator of JSESSIONID, to be able to create custom values of this cookie, based on user's login? Why do I need this: I have a load balancer with "sticky sessions", configured to route requests with the same JSESSIONID to the same server, and I want to prevent situation, when same user can start two different sessions on different servers.

  • Apache2 Segfault - need help interpreting this coredump (suspect cause is memcache / php session related)

    - by WayneDV
    Three Apache2 web servers running a PHP 5.2.3 web site. We're using Memcache to cache rendered pages but also as the storage engine of the PHP Sessions. At peak traffic times we're getting Apache segmentation faults on all three web servers and all HTTPD child processes segfault. My gut tells me that the increased Memcache traffic is stopping PHP sessions from being created or cleaned up and thus the processes die. Is it possible for someone to confirm that from the following? : #0 _zend_mm_free_int (heap=0x7fb67a075820, p=0x7fb67a011538) at /usr/src/debug/php-5.3.3/Zend/zend_alloc.c:2018 #1 0x00007fb665d02e82

  • ASP.NET Session Management - which SQL Server option?

    - by frumious
    We're developing some custom web parts for our WSS 3 intranet, and have just run into something we'd like to use ASP.NET sessions for. This isn't currently enabled on the development server. We'd like to use SQL Server as the storage mechanism, because the production environment is a web farm with very simple load-balancing. There are 3 options you can choose from to set up the SQL Server session storage, tempdb, default separate DB, named DB. Both tempdb and default separate DB create a new DB to store certain information in; tempdb stores the actual session info in tempdb, which doesn't survive a reboot, and default separate DB stores everything in the new DB. Since you've got to create the new DB either way, my question is this: why would you ever choose to store the session info in tempdb? The only thing I can think of is if you'd like to have the ability to wipe the session by rebooting the server, but that seems quite apocalyptic!

  • Azure - Microsoft.IdentityModel not found

    - by Andy
    Hi There, I'm working with a WCF service in Azure, which uses Windows Live ID authentication with the recent deviceid requirements. When I host my WCF service locally in the compute emulator, it works properly, but when I deploy the cloud service to Azure and call it the same way (from another project that uses the WCF service as a service reference), I get the error: Could not load file or assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I found this post : http://social.msdn.microsoft.com/Forums/en-US/netservices/thread/cd139b5c-ad12-4298-af2f-1b2d0136a977 But there are a few problems: 1. I don't seem to have access to Microsoft.IdentityModel, only System.IdentityModel. I'm not sure why it's searching for something in 3.5 at all, as I'm building in .NET 4.0. 2. When I choose to "copy to local" on System.IdentityModel, it doesn't change anything. Any help? I would appreciate it! Best Regards, Andy

  • Connection string in app.config in a class library

    - by Copeleto
    I am creating solution and inside I have three projects: A WCF Service Library Project A DataAccess Project (Class Library) A Web site for hosting WCF service The implementation of the service is on the project # 1, but in order to access the DataBase I use a second project that implements the data access using a class library project. That problem is in order to get data access I need to configure a connection string, but that connection string must be configurable in a production environment, I meant in production I am going to deploy the site, which is a very simple project that contains only a reference WCF Service Library Project then a guy from database department will configure the connection string. In development I have an app.config on the data access project but when I do the release that app.config is embedded on the dll. Any ideas how can we achieve our purpose

  • How to add a privilege to an account in Windows?

    - by mark
    Given: A VM running Windows 2008 I am logged on there using my domain account (SHUNRANET\markk) I have added the "Create global objects" privilege to my domain account: The VM is restarted (I know logout/logon is enough, but I had to restart) I logon again using the same domain account. It seems still to have the privilege: I run some process and examine its Security properties using the Process Explorer. The account does not seem to have the privilege: This is not an idle curiousity. I have a real problem, that without this privilege the named pipe WCF binding works neither on Windows 2008 nor on Windows 7! Here is an interesting discussion on this matter - http://social.msdn.microsoft.com/forums/en-US/wcf/thread/b71cfd4d-3e7f-4d76-9561-1e6070414620. Does anyone know how to make this work? Thanks. EDIT BTW, when I run the process elevated, everything is fine and the process explorer does display the privilege as expected: But I do not want to run it elevated. EDIT2 I equally welcome any solution. Be it configuration only or mixed with code. EDIT3 I have posted the same question on MSDN forums and they have redirected me to this page - http://support.microsoft.com/default.aspx?scid=kb;EN-US;132958. I am yet to determine the relevance of it, but it looks promising. Notice also that it is a completely coding solution that they propose, so whoever moved this post to the ServerFault - please reinstate it back in the StackOverflow.

  • Silverlight 5 App Crashing

    - by bbagfh
    I have a silverlight 5 app that makes some WCF requests. When the silverlight app is hosted locally on an IIS 7.5 server it works fine, but when I run it from a remote IIS6 box there are issues. The app loads fine and presents the login UI. After trying to log in, a couple WCF service calls are made (successfully), but the response causes silverlight to stop responding and the browser eventually asks to kill the non-responsive silverlight app. I am mostly confused because it works fine in IIS 7.5 Note that I am accessing the same WCF services hosted on a remote box in both instances, and both times I am getting successful responses. It is only in IIS6 that the app becomes non-responsive.

  • OutOfMemoryException, stack size is huge, large number of threads

    - by Captain Comic
    Hello, I was profiling my .net windows service. I was trying to discover OutOfMemoryException and discovered that my stack size is huge and is growing because the the number of threads keeps growing. Each thread gets 1024 KB on Windows x64 machine. Thus when my app has 754 threads the stack size would be 772 MB. The problem for me is that i don't know where these thread come from. Initially my app has a very limited number of threads and they keep growing with time. I have two suspicions - either these threads are created by WCF or by database connection. My application uses both WCF and datasets. Also I tried to profile my app in Ants do Trace i can see large number of System.ServiceModel.Channels.ClientReliableDuplexSessionChannel and this number is increasing with time. I can see thousands of these objects created. So what I want to know is who is creating threads (tools to discover, profilers) and if it is WCF who is creating these threads.

  • IWAB0399E Error in generating Java from WSDL: java.io.IOException: ERROR: Missing <soap:fault> elem

    - by DanO
    I have a WCF 4.0 service for internal use. Another team is trying to consume it in Java. IWAB0399E Error in generating Java from WSDL: java.io.IOException: ERROR: Missing <soap:fault> element inFault "PasswordReuseFaultFault" ... One source suggests it may be a Soap 1.1 vs. Soap 1.2 issue Indeed my WCF generated WSDL <wsdl:fault name="PasswordReuseFaultFault"> <wsp:PolicyReference URI="#blah_blah_blah_PasswordReuseFaultFault_Fault"/> <soap12:fault name="PasswordReuseFaultFault" use="literal"/> </wsdl:fault> notice the <soap12:fault>instead of the expected <soap:fault> I'm pretty sure that is the cause of the problem. How do I get WCF to generate soap 1.1 WSDL ? or What should I tell the Java team to do so their tools can understand the newer protocol?

  • Regarding Creating Business application using Silverlight

    - by vijay
    Hi, We are in the conceptual phase to create a relatively medium size enterprise business product application using Silver light 4.0, Entity Framework and WCF. 1. Is it adivceable to use Silverlight 4.0 for this enterprise business application development or should we go in for MVC.NET / ASP.NET? 2. We have planned to use REST based WCF service. How complex would it be to write the information back to the REST WCF service? I appreciate and welcome your advice / suggestion. If you need any further details do let me know, i will be happy to share. Thanks in advance.

  • Several different project types in solution use same class. Where can I place this class?

    - by user3605366
    I have one solution with 3 related projects: 1) a Windows console app that reads data and stores it to a mssql DB, 2) WCF service that will retrieve from mssql data, 3) website that will read from the WCF. There could be other projects in the future. The first two projects (and any related future projects) use a Sqlhelper class. Should I create a separate project for it? The most ideal one would be a class library, but I don't know if a WCF invoking a DLL is correct. Any help is appreciated. Thanks.

  • [N]Hibernate Sessions

    - by Jaimal Chohan
    A silly question, perhaps, but at this time of night, StackOverFlow is my only friend. I'm playing with NHibernate and wanted to factualize these 2 statements regarding Sessions in web applications. 1) You should only ever have 1 ISessionFactory per database for the lifecycle of an application. 2) You should only have 1 ISession per HttpRequest or batch of HttpRequests (i.e. conversation) [I don't want tool or framework recommendation, just want to confirm the above]

What I want to find out is a way to force .net to create another session id instead of using the one that came with url. Is it possible?

  • cleaning up expired sessions with a custom SessionStateStoreProvider

    - by CountCet
    I'm implementing my own SessionStateStoreProvider with a schemaless database. It's a little hard to tell from the documentation but it seems as though I will have to have a separate process for cleaning up expired sessions since the database will not have a way to notify the session state store that a session has expired. Am I wrong about this? I haven't seen an alternative example for overriding the SetItemExpireCallback method.

    What is the best way to manage user authentication/sessions in a web app, ideally in a clustered environment, using Spring Framework/MVC? I thought of creating a login bean that creates a jsession for authenticated users and then using AOP to check for the jsession before each controller method inovcation. If there isn't a better way, what are some possible alternatives? Thanks.
