C# - Store Class Instance (helper Class) In Cache?

Jun 30, 2010

I have a class instance which is created by using Activator.CreateInstance() method. That class instance contains helper methods which are frequently used throughout the application. In order to avoid creating the instance multiple times, I'm just thinking about implementing an appropriate caching mechanism. The following consideration should be taken into account:

1) I can't use static class and methods.
2) There are around 6 instances (1 instance per class) per App Domain.

Architecture :: Cache The Full List Of Objects In Http Cache On The Service Tier And Page In Memory?

Feb 25, 2011

We have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.

Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?

New-Cache Parameters For AppFabric Cache When Storing.NET Session State

Jul 28, 2010

What are the "optimal" parameters for creating an AppFabric cache when you will be storing session state in the cache? MSDN Cache-Related Commands

Powershell command line:

New-Cache [-CacheName] <String> [-Eviction <String>] [-Expirable <String>] [-Force [<SwitchParameter>]] [-NotificationsEnabled <String>] [-Secondaries <Int32>] [-TimeToLive <Int64>]

[code]...

Since I don't want my sessions to be removed unless the session has been abandoned either via code or Session Timeout...For eviction, I would think "None" and for expireable, I would think False.I have tested and calling Session.Abandon does remove the object from the cache. I have also tested to see if by extending my session, the session object in cache is also extended. This does seem to work the "correct" way.

Data Cache Support Background Population Of Cache Entries?

Aug 1, 2010

We have a data driven ASP.NET website which has been written using the standard pattern for data caching (adapted here from MSDN):

public DataTable GetData()
{
string key = "DataTable";
object item = Cache[key] as DataTable;

[code]...

The trouble with this is that the call to GetDataFromSQL() is expensive and the use of the site is fairly high. So every five minutes, when the cache drops, the site becomes very 'sticky' while a lot of requests are waiting for the new data to be retrieved.

What we really want to happen is for the old data to remain current while new data is periodically reloaded in the background. (The fact that someone might therefore see data that is six minutes old isn't a big issue - the data isn't that time sensitive). This is something that I can write myself, but it would be useful to know if any alternative caching engines (I know names like Velocity, memcache) support this kind of scenario. Or am I missing some obvious trick with the standard ASP.NET data cache?

C# - Maximum Length Of Cache Keys In HttpRuntime.Cache Object?

Feb 24, 2010

We are using HttpRuntime.Cache API in an ASP.NET to cache data retrieved from a database.

For this particular application, our database queries feature a LOT of parameters, so our cache keys look something like this:

table=table1;param1=somevalue1;param2=somevalue2;param3=somevalue3;param4=somevalue4;param5=somevalue5;param6=somevalue6... etc...

we have so many parameters that the cache key is several hundred characters long. is there a limit to the length of these cache keys? Internally, it is using a dictionary, so theoretically the lookup time should be constant. However, I wonder if we have potential to run into some performance/memory problem.

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?

C# - Application_End() Cannot Access Cache Through HttpContext.Current.Cache

Dec 12, 2010

I want to be able to maintain certain objects between application restarts.

To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start().

I currently have a cache helper class, which uses the following method to return the cached value:

return HttpContext.Current.Cache[key];

Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk.

Question: how can I access the cache items during Application_End()?

C# - Web Application Cache Versus Database Cache

Jan 14, 2010

Im building a image gallery which reads file from disk, create thumbnails on the fly and present them to the user. This works good, except the processing takes a bit time.

I then decided to cache the processed images using the ASP .NET Application Cache. When a image is processed I add the byte[] stream to the cache. As far as I know this is beeing saved into the system memory. And this is working perfect, the loading of the page is much faster.

My question is if there are thousands of images which gets cached in the Application Cache, will that affect the server performance in any way?

Architecture :: Differences Between MVC And 3-Layer?

May 11, 2010

In my opinion, these architectures have some differences, such as:

1. 3-layer is a linear architecture, but MVC is a triangle architecture.

2. Presentation Layer of 3-layer includes View and Controller of MVC? And Model of MVC includes Business Layer and Data Access Layer of 3-layer

I think 2 differences above are not obvious or are incorrect!
