State Management :: Use An Object From The Cache In A Mvc View?

Sep 24, 2010

I am working with mvc and i am trying to get acces to a object that is in the cache.In the Application_Start() of Global.asax.cs i create and store an object in the cache like this:

Translator translator = new Translator();
HttpContext.Current.Cache.Insert("Translator", translator, null, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration);

Translator holds a dictionary with translations.Now i want acces to this object from the cache to use functions and get values from the dictionary.I know i can acces it like this HttpContext.Current.Cache.Get("Translator") or Cache.Get("Translator") in the views But how can i use the functions of the object ? The meaning of the cache is to have a object that is accesable througout the webapp right ?

Do i have to make an object and asses the value of the Cache.Get("Translator") to it, so i can use the functions or is there another solution?

State Management :: Session Time-out : Object Reference Not Set To An Instance?

Oct 26, 2010

I noticed that when i am debugging my web application in Visual Studio 2005 using IIS, after about 10-15 minutes of inactivity, when I do something in the application such as a postback, I get an immediate error saying: "object reference not set to an instance" and my code breaks somewhere.Is my assumption correct that this is because my session has timed out? ( i do have a 15 minute default session time)my next question is, how do I display or set a way so that like many other pages, when the session has expired, a message will say: "This page must be refreshed" or "Your session has expired, click okay to refresh page" and start over again?

State Management :: Cache Always Removes Itself?

Aug 11, 2010

I have some weird problem. We're using Windows Server 2008 R2 x64 (8 Cores and
8 GB RAM) with IIS 7.5 and ASP.NET MVC 2.

I always cache (simple) stuff via the context cache and it seems like 9 out of 10 immediate page refreshs the Cache["MyKey"] is always null, even though there's no memory limit set on the pool and the server has lots of free memory.

I add expiring data via:


When just doing: Cache.Insert("MyKey", myObject); or Cache["MyKey"] = myObject; I get the same result (cache is almost always null for that key).

As you can see I added a callback, which writes the CacheItemRemovedReason to a text file, and the text file says CacheItemRemovedReason.Removed for MyKey. The doc for CacheItemRemovedReason.Removed says, that I call Remove/Insert on it, even though in my whole project there's no "Remove"-calls, just simple if(Cache["MyKey"] == null) {Cache["MyKey"] = ...} stuff.

I tried adding:

<caching><cache disableMemoryCollection = "true" disableExpiration = "true" privateBytesLimit="0" percentagePhysicalMemoryUsedLimit="90" privateBytesPollTime="00:02:00" /></caching>

to my web.config file in the System.Web-section but nothing changed :(

why Cache["MyKey"] is almost always null?

State Management :: User Profile Cache?

Apr 5, 2010

I am looking for an elegant (i guess as elegant as it can be) solution to caching a users profile on login (whether it is session, cache, cookie, etc) and keeping it in sync when a users profile is changed. How do you guys handle this? Just simply call a Flush() method in your Save() method that invalidates the cache?

State Management :: Output Cache And Not IsPostBack

May 18, 2010

I'm trying to cache a complex page with lots of controls on it so that if the user navigates to it later it will look like it did when he last saw it.The page has controls which post back and other controls are populated depending on the selections.

I'm using [Code]....
after the <@ Page directive.

What happens is that a postback gets the cached page, so no processing and it looks the same regardless of user selections. So far so good. But if I browse to another page and return by a link, the cached version is ignored and the default page is created again. This is more or less the opposite to what i want.

I attempted to use the validation callback to ensure that a postback resulted in a new version, and that worked, but it still ignored the cached page if it wasn't a postback.I realise that it will need more work to ensure each user gets their version of the page from the cache, but why bother if this doesn't work.

State Management :: Cache Vs Static Variable?

Sep 24, 2010

I know the big difference, but one thing is confusing me. Cache works only on a single machine on webfarm and to make it globally we use Velocity or memcache.So is static does same, or is it already work globally ?

Cache["someid"] = "value"; //this will only work on single machine cache,

static string abc = "value"; // will this work on single machine or globally ?

State Management :: Populate Dropdown From Cache

Oct 6, 2010

I wanted to know the best practice for caching data. Say I have some control example a dropdown list which is populated from my db. Now this dropdown is global and used across many pages. I was thinking of not going to database everytime to fetch data for this dropdown and put the result in Cache. And then populate this dropdown from cache. Is this a good practice or if there is another approach. Can I store my datareader in cache and then use it globally. Also could I do this in application start event?

State Management :: Sharing Cache Between Two Web Applications In The Same Solution

Jul 7, 2010

I have an solution in which there are two web application projects (client website and admin website) and also a class liabrary project in the same solution . In the live production server, the admin web app is within the client app (eg: client site= [URL] and admin site=[URL]). A class (with static variables) in class liabrary is userd to cache data. My problem is that i cannot get the changes to the static cache by one web project reflected to the other (becoz, i think, they seem to load in seperate appdomains).

State Management :: Storing Dataset In Application Cache?

Nov 29, 2010

I am writing a web page that returns a small volume of data from a database table. The database is polled every 1 second and the data will be the same for every user. As every user is accessing the same data, there is no need for each user to poll the database and use up db resource.

Therefore, I think I should be using application caching to store the data in a dataset. However, I am slightly stumped as to how to do this.... because how can i ensure that the dataset is kept up to date.

The only way I can think to do this is to have a master user/session (i.e. the first session in the application) that keeps the cache object updated every second, then other users can use that cache object. If the first session ends, then the next requestor of the cache will pick up responsibility for keeping the dataset up to date.
