State Management :: Deleting Data In Cache Memory?

Mar 4, 2011

I 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?

Apr 1, 2010

Im working on my first ASPX webpage now, and Im wondering if there is some way to make a cache?

With a cache, I mean a list of variables that gets transferred from a db to for insance a hashtable the first time a user loads the page. When the next user loads the page, the db doesent get touched, but the variable is collected from the hashtable.

I tried to make a static class, but it re-loaded for each time I refreshed the page.

State Management :: SQL Database - Cache Expires The New Data Is Picked Up?

Dec 17, 2010

I'm running a website on a SQL 2008 database. At the moment most of my data is in cache but what I want to do is be able to update the data on a regular basis, say every 3 hours, maybe more frequently. Obviously I can set the cache to expire and pick up new data, but how can I replace part of the database (because some tables are populated by the user) in the background, so that when the cache expires the new data is picked up?

I notice when I upload data through VS, it wont let me upload if the DB is in use - so how do I get round issues like this?

State Management :: Multiple DataTables In Memory - Best Practice?

Jul 9, 2010

I have a DataTable which holds information on truck routes. When the user click on a route it display another table with details about the stop along that route. When they click a stop it shows what items were picked up at that stop. Three separate pages with 3 distinct DataTables. Currently I am storing them in the session. Normally, I would use the view state since the data only needs to live on that page. The reason I use the session is because each page is part of a Master pagelayout. There is an export button in the master page which gets the data in the session and exports it to an excel file. The issue is that when the user goes to the item level detail and uses a quick navigation link back to the route information the data for route is not reloaded into the session, just the page. If the user clicks export it will export the data set from the item level detail even though it is not displayed on the page

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:

[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?

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

Sep 24, 2010

I 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?
