View 2 RepliesState Management :: Cache Always Removes Itself?
Aug 11, 2010I 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:
[Code]....
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, 2010I 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?

View 1 RepliesState 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, 2010I 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 ?
eg
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 :: Use the Cache to see The Grid Update?
May 9, 2010 I have a page that has a grid view.
The user selects a person from a dropdown list and then clicks a button that adds the users info as

Adding the new row involves doing an insert and rebinding the grid which is a slow process.
How do I use the cache to see the grid update right away?
State Management :: Populate Dropdown From Cache
Oct 6, 2010I 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 :: Use An Object From The Cache In A Mvc View?
Sep 24, 2010I am working with asp.net 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 :: Sharing Cache Between Two Web Applications In The Same Solution
Jul 7, 2010I have an asp.net 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).

View 4 RepliesState Management :: Storing Dataset In Application Cache?
Nov 29, 2010I 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.

View 1 RepliesState Management :: Deleting Data In Cache Memory?
Mar 4, 2011I have a webpage which displays some data along with a banner. The banner image is stored in the database with parameters "Pagename" and "form".
The application has been coded in such a way that when the page loads , a function checks for the banner in cache memory first with the parameters "pagename" and "form". It the banner does not exist, the new banner is retrieved from the database and is added to the cache memory. Next time when the same page is called, the banner is displayed from the cache memory avoiding the DB to be hit everything to get the banner.
Now, I do not want a specific banner to be displayed on the page. I have removed that banner from the DB but the banner still gets displayed as this banner is still there in the cache memory.
Is there any way to delete the banner which exists in cache memory without making any code changes?
State Management :: Cache Settings On Shared Application Pool?
Sep 17, 2010I have several web applications on a server using the same application pool. The worker process usually takes a lot of ram but usually only from one application. I can successfully limit the cache usage by setting "PrivateBytesLimit" in web.config file when the application uses it own dedicated application pool.
Does anyone know how this setting will be applied when using shared application pool? Is it per application, per worker process or per application pool? Also if it is not per application which setting from which application will be applied?
