We have 5 balanced web servers with various websites. What I am trying to achieve is to ensure a single login. i.e. the same user account cannot login to the same website more than once at any given time. The method i'm considering for solving this, is to share session amongst the servers so I can control which session is assigned to w...
I'm looking for a good way to visualize ASP.NET session state data stored in SQL server, preferably without creating a throwaway .aspx page. Is there a good way to get a list of the keys (and serialized data, if possible) directly from SQL server? Ideally, I'd like to run some T-SQL commands directly against the database to get a list o...
Is there a way to determine the number of users that have active sessions in an ASP.NET application? I have an admin/tools page in a particular application, and I would like to display info regarding all open sessions, such as the number of sessions, and perhaps the requesting machines' addresses, or other credential information for eac...
I have one of those "I swear I didn't touch the server" situations. I honestly didn't touch any of the php scripts. The problem I am having is that php data is not being saved across different pages or page refreshes. I know a new session is being created correctly because I can set a session variable (e.g. $_SESSION['foo'] = "foo" and p...
If i hit a page which calls session_start(). How long would I have to wait, so that if i was to refresh the page, I was issued a new session ID? ...
We have a strange problem occurring once in a while on our servers. It usually happens when one or more of our web applications are upgraded. Debugging the problem has gotten me this far... During the processing of a request: In the ASP.NET application we put an object in session In code running later (same request) we look up that sa...

I'm using ASP.NET, with session state stored out of process in SQL Server. When a page request begins, are the entire contents of a user's session retrieved from the DB, deserialized, and sent to the ASP.NET process in one fell swoop, or are individual objects transferred to the ASP.NET process only as needed? Basically, I have a page t...
I am running a Django through mod_python on Apache on a linux box. I have a custom authentication backend, and middleware that requires authentication for all pages, except static content. My problem is that after I log in, I will still randomly get the log in screen now and again. It seems to me that each apache process has it's own py...
I have an API that is dependent on certain state information between requests. As an easy first version of the code, I am simply using PHP session's to store the state information instead of something more advanced (APC, memcache, DB). Throughout my initial testing in a web browser, everything worked perfectly. However, it seems that whe...
I've been working with sessions, MVC design and object oriented PHP. Where should I save or retrieve data from a session? I would like to retrieve it from within methods so I don't have to pass the data to the methods. Whats the best practice? ...
I noticed sometimes with my parent/child objects, or many-to-many relationships, I need to call either SaveOrUpdate, or Merge. Usually, when I need to call SaveOrUpdate, the exception I get on calling Merge has to do with transient objects not being saved first... Please explain the difference between the two. ...
I'm trying to host a PHP web site that was given to me. I see this warning: Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can...
When using the .NET WebBrowser control how do you open a link in a new window using the the same session (ie.. do not start a new ASP.NET session on the server), or how do you capture the new window event to open the URL in the same WebBrowser control? ...
I read some of the answers on here re: testing views and controllers, and mocking, but I still can't figure out how to test an ASP.NET MVC controller that reads and sets Session values (or any other context based variables.) How do I provide a (Session) context for my test methods? Is mocking the answer? Anybody have examples? Basically,...
In my understanding of Servlet, the Servlet will be instantiated by the Container, his init() method will be called once, and the servlet will live like a singleton until the jvm is shut down. i do not expect my servlet to be serialized, since it will be constructed new when the app server recovers or is starting up normally. the servle...
I need to be able to use WCF Session capability in a Silverlight application. Currently Silverlight only supports basicHttp binding, so this is impossible. My thoughts are to create a middle piece with wsHttp caapabilities that will handle the Sessions for me and my sessionless Silverlight app can pass in the SessionID guid. Is this ev...
I'm running PHP on Windows/IIS. My session variables don't seem to be preserved from page-to-page. This code //echos out the session variables in a nice format for inspection echo "<p><pre>"; print_r($_SESSION); echo "</pre></p>"; outputs blank values, like this Array ( [s_firstvar] => [s_var2] => ...
I want to compare the current value of an in-memory Hibernate entity with the value in the database: HibernateSession sess = HibernateSessionFactory.getSession(); MyEntity newEntity = (MyEntity)sess.load(MyEntity.class, id); newEntity.setProperty("new value"); MyEntity oldEntity = (MyEntity)sess.load(MyEntity.class, id); // CODEBLOCK#1 ...
