State Management :: Where Is The System.Web.Caching.Cache Actually Stored

Nov 25, 2010

I am using this to store my user information for authentication. I'd like to know where this is actually being stored? I know that people suggest to store the Session state in SQL. Is this necessary for the Cache as well?

Architecture :: Distributed Caching / Keeping Cache In Sync Between Multiple Webservers Or Even Better Farm Cache Management To Another Server?

Feb 26, 2010

I've got a web application that runs of a state server. It looks like soon it may need to distributed and there will be two web servers behind a load balancer.

This works great for session state but my next challenge is Cache

My application leverages heavily of cache. I understand ASP.Net 4.0 will be offering more here but nothing much has been said about the how too.

There are two challenges that I face

1). Each webserver will have its own copy of cache whereas it would be more efficient to put this to a third server the same as session state is put to state server.

2). The real challenge is keeping cache in sync if a simple dataset derived from the database is changed my code dumps that cache item and reloads the cache. That's all well on one webserver but webserver number two wont know to drop that particular cache item and reload it. This could cause some unexpected problems in the application.

For scenario number 2 I could attempt to do some smart coding so server number two knows to dump the cache and reload it.

My guess is someone else has already been here before and there's probably a better implementation approach rather than writing extra code.

Does anyone know how I could achieve the goal of keeping Cache in sync between multiple webservers or even better farm Cache management to another server?

System.Web.Caching.Cache Doesn't Seem To Refresh Itself On Time

Jan 27, 2011

I am using System.Web.Caching.Cache in an assembly used by my website.

I have set some key expiration (absolute expiration) to be 10 seconds (just for debugging).

I have also set a callback upon key removal.

The problem is that I see that the cache is getting refreshed after something like 20 seconds and not 10.

I am using HttpRuntime.Cache for this.

I would like to show a code sample, which can shed more light:

[code]....

What could be the problem ?

C# - System.Runtime.Caching (ObjectCache) - How To Inspect Cache Policies

Feb 8, 2011

I'm making use of the new .NET 4.0 Caching namespace: System.Runtime.Caching.Now, i'm just doing some prototype/fiddling with the new API, in order to work out the best fit for the real app.In line with that, i'm trying to create a page (ASP.NET MVC) that basically dumps out everything in the cache, particularly the following info:

Cache Key
Cache Object
Cache Policy (expiry date, etc)
Cache Dependencies (if any)

However, i can't seem to get anything except the key/object.Here's the code i'm currently playing with:

public ActionResult Index()

State Management :: ObjectDatasource Caching

May 21, 2010

I have an issue with the object datasouce caching. Users are seeing other peoples cached records when they click next on the grid. It looks as though the caching is shared among users. Bascially when the user get to the screen they have date filters so they can further filter down the records. If another user it in at the same time and the first user hits next they get the second users filtered records.

State Management :: Using Caching While Storing Variables?

Jun 1, 2010

I've begun building a bit of a framework that I wouldnt mind working with. The idea is to create a framework that makes it even easier to create CMS addons (So basically a CMS framework).

One of my goals with this project, was having all modules made within the framework automatically support version without any extra coding.

More to the point, the way that I started building this, many pieces (Lots had to do with the versioning system) became interlinked. A version Object in the code related directly to a Module Object and vice versa, therefore the class definitions for each relate to eac otherh. (So having only the Module object, i could access the versioning object and all of its properties). My issue with this is of course what happens if i have both the module and versioning objects in my code simoultaneously, resulting in having not just duplicates of the data within the code, but (perhaps) infinite amounts, killing the app.

So what im wondering is, what if my modules properties where stored within the cache? Ie if i had the Module object, and it had the property ID -- Then the data for ID would be stored in the cache within the module object. Referencing the value simply retrieves the value from the cache if it exists there, and the SQL database if it doesnt. This way, all instances of the module that may be running at the same time will have access to the same information, at the same time, and hopefully causing it to use less space in total.

I would then add a function, so that if a developer was loading a rarely used module, or dident want to occupy cache space with large amounts of data, then they could just call a Dispose function that would remove the data from the cache.

Does this method sound reasonable? I know this probably isnt what the cache is designed for -- but I cant think of any other way to do this without having an infinite loop of objects referring to each other, or causing huge discrepencies from having different instances of objects referencing values that should be the same, but arent because they are technically different instances.

State Management :: Caching With Static Classes?

Jul 3, 2010

Currently I have my data cached in Datasets in a static class. I was talking to my cousin's husband, who works as a C# developer for our local Telecom company.

Basically, I'm pretty new to ASP.NET and although to me having cached data in a static class makes sense to me, when I talked to him about it, he said there might be a problem when the site goes live, as on a web server more than one instance of the class may be created.

He did say this was a theory, and it was an area he didn't know an awful lot about, so I thought I'd ask some of you ASP.NET gurus to see if what I've done is totally wrong or not.

State Management :: Caching A List Of Data?

Jul 26, 2010

I have a List (Table) of Data that I display in a Grid View. For now lets just assume I have a List<CustomObject> cList that I give to my GridView.DataSource(). I have a AJAX call (from a DropDown on the Page) that enables me to filter the Data in the GridView. This works. For now, I re-fetch the data from the DB, and filter it.I am wondering if there is a more efficient way of doing this i.e. to save the data the first time I get it, and then display a filtered list of that data when requested. I attempted to save the data as private variable on the Page, but it seems that Page gets recreated for the AJAX call. My attempt looks like:

[Code]....

[Code]....

This page is accessible anonymously - so there is no User Profile or something like that. P.S. I put my code in the Insert Code Dialog, but it does not seem to format it correctly. Sorry about that.

State Management :: Best Practise For Caching Objects For A List Of?

Dec 7, 2010

I've created a blog for my first asp.net website. Ive got a blog class as my object. Ive created a number of methods to access my blog articles using LINQ to SQL.

Each method returns a list of objects ready to be used in the appropriate web user control.

In my head i need to cache these lists of objects that are returned, but need to know the best way of approaching this. So i have come up with two possible options

1: Make one method to retrieve all blogs in a list<Blog> and cache this list to be used for all other methods or

2: Cache only the required methods that really need it.

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?
