Caching - How To Hold Current Date In Cache

Jul 28, 2010

I am building a web application using asp.net (c#) and lingtosql. When I perform update operations on my db I update my classes. I use gridview to bind to update information. When I relay solely on the database the page's take very long to load. When I relay solely on the cache, I have old data. What workarounds do I have for have asynchronous cache updating, yet not overload the database with endless requests (I'd like to update the cache only if there has been a change in the database itself, and perform the update operation asynchronously).

C# - Caching Through HttpContext.Current.Cache Or Just A Static?

Mar 28, 2011

Last night I wrote up my first IHttpModule to do some request processing. I'm using a regular expression to inspect the raw url. The IHttpModule will be called on every request, so it seems reasonable to do some sort of caching of the regular expression object to prevent creation of it on every request.

Now my question... what is better: use the HttpContext.Current.Cache to store the instantiated object or to use a private static Regex in my module?I'm looking forward to the reasons why. Just to clarify: the regex will never change and thus always be the same thing.

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()?

This code cache whole page.But, my site has user infomation on top like this ASP.net. The user info "Signed as userid | Edit Profile | ..." section should be changed when user sign in/out. But rest of the page is always same and it's good to Cache.

If the above code is used, the user info on top also cached and give wrong info to user.

Caching - How To Cache A List Of Objects

Jan 23, 2010

I have a List of objects in an asp.net page. when the page loads in the browser for the first time, I fetch data from the database, create objects with those data and populate the list. All these are done inside the page load event handler. Now when the page is posted back to the page, the previous list is gone, since the variables were all freed.

How can I cache that List, so that when this page is posted back, all my objects are available?

Caching - What Is The Default Serialization Used By The HttpRuntime.Cache

Jan 29, 2010

what the default serialization used by the ASP.net HttpRuntime.Cache is? Is it Binary, XML, something else?

I am populating a generic List with multiple objects of the same custom type. The custom type is a POCO, there is nothing special about it. All of its properties are public with { get; set; }, it is public, it has no inheritance, it has no interfaces. In fact it is much less complicated than many other objects which we are caching which work without issue. I have tried adding the [Serializable] attribute to the custom class and it has no effect.

I add the list to the cache with a unique key. The list has been verified as populated before it is inserted into the cache, the objects in the list have been verified as populated as well. But when the list is pulled back out of the cache it is an empty list (NOT NULL), it simply has no items in it. This means that the list is being added to the cache and is retrievable but for some reason the cache is having issues serializing the objects in the list.

I just find this freaky weird since I have another list of custom objects which are much more complicated (consisting of Inheritance, Interfaces, and also containing Properties which are generic lists of other complex objects) and the caching of those lists work without issue.

Both the working and non-working list are being managed in C# classes outside of the ASP.net user controls which consume the cached data. Both of these cache handling classes call the exact same Cache Manager class singleton instance which wraps the HttpRuntime.Cache to provide typed methods for pull and pushing objects into the cache.

Here is the class

Caching - Controlling Output Cache Memory Usage?

May 17, 2010

I would like to use output caching with WCF Data Services and although there's nothing specifically built in to support caching, there is an OnStartProcessingRequest method that allows me to hook in and set the cacheability of the request using normal ASP.NET mechanisms.

But I am worried about the worker process getting recycled due to excessive memory consumption if large responses are cached. Is there a way to specify an upper limit for the ASP.NET output cache so that if this limit is exceeded, items in the cache will be discarded?

I've seen the caching configuration settings but I get the impression from the documentation that this is for explicit caching via the Cache object since there is a separate outputCacheSettings which has no memory-related attributes.

Here's a code snippet from Scott Hanselman's post that shows how I'm setting the cacheability of the request.

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:

Caching User Control And Clearing That Cache Programmatically?

Jul 13, 2010

I'm trying to cache user controls and on some pages i want to cache single objects. There are multiple ways of implementing caching, and my head is breaking over it.

The way I see the caching options now:

You have the PartialCaching option which is set to cache the control for 30 minutes, and after that it clears itself... You have the varyByParam to identity the page by its querystring paramaters... or other vary options

But i just cant find an appropriate way to add caching to a control, and be able to clear the caching programmatically when i update one of the objects used in the control from the backend.

You can do HttpContext.Current.Cache.Insert(), which accepts a key on which you can destroy the caching item later by using remove... This can save objects in cache but can you use options like varyByParam?

My questions are burnt down to two:

Is there a way to clear the caching on specific user controls from the code? If yes, can this be done according to the varyby options? How would the object caching respond to logged in users or anonymous users using Insert()?

EDIT: I'm caching multiple things.... And I'm really flabbergasted in which choice to make referring to caching. Can the Cache.Insert be varied by Parameters?

The main problem is peopling editing things from the backend, which needs to trigger an event that reinstantiates or clears all caching items referring that object.

C# - Caching W/file Dependency: Static Var Vs. AspNet Cache Vs. Memcached

Sep 29, 2010

TL;DR: Which is likely faster: accessing static local variable, accessing variable stored in HttpRuntime.Cache, or accessing variable stored in memcached?At work, we get about 200,000 page views/day. On our homepage, we display a promotion. This promotion is different for different users, based on their country of origin and language.

All the different promotions are defined in an XML file on each web server. We have 12 web servers all serving the same site with the same XML file. There are about 50 different promotion combinations based on country/language. We imagine we'll never have more than 200 or so (if ever) promotions (combinations) total.

The XML file may be changed at any time, out of release cycle. When it's changed, the new definitions of promotions should immediately change on the live site. Implementing the functionality for this requirement is the responsibility of another developer and I.

Originally, I wrote the code so that the contents of the XML file were parsed and then stored in a static member of a class. A FileSystemWatcher monitored changes to the file, and whenever the file was changed, the XML would be reloaded/reparsed and the static member would be updated with the new contents. Seemed like a solid, simple solution to keeping the in-memory dictionary of promotions current with the XML file. (Each server doing this indepedently with its local copy of the XML file; all XML files are the same and change at the same time.)

The other developer I was working holds a Sr. position and decided that this was no good. Instead, we should store all the promotions in each server's HttpContext.Current.Cache with a CacheDependency file dependency that automatically monitored file changes, expunging the cached promotions when the file changed. While I liked that we no longer had to use a FileSystemWatcher, I worried a little that grabbing the promotions from the volitile cache instead of a static class member would be less performant.

(Care to comment on this concern? I already gave up trying to advocate not switching to HttpRuntime.Cache.)

Later, after we began using HttpRuntime.Cache, we adopted memcached with Enyim as our .NET interface for other business problems (e.g. search results). When we did that, this Sr. Developer decided we should be using memcached instead of the HttpRuntime (HttpContext) Cache for storing promotions. Higher-ups said "yeah, sounds good", and gave him a dedicated server with memcached just for these promotions. Now he's currently implementing the changes to use memcached instead.

I'm skeptical that this is a good decision. Instead of staying in-process and grabbing this promotion data from the HttpRuntime.Cache, we're now opening a socket to a network memcached server and transmitting its value to our web server.This has to be less performant, right? Even if the cache is memcached. (I haven't had the chance to compile any performance metrics yet.)On top of that, he's going to have to engineer his own file dependency solution over memcached since it doesn't provide such a facility.

Wouldn't my original design be best? Does this strike you as overengineering? Is HttpRuntime.Cache caching or memcached caching even necessary?

Forms Data Controls :: Caching DataTable - Create/cache Multiple DataTables?

Jul 23, 2010

Among the many aspects of asp.net that I haven't focused my development on yet is caching. I have a perfect application for it now, I think, with a GridView that sits inside a repeater, and is bound in the Repeater ItemDataBound event. The contents of the GridView will remain static for each Repeater data item for each Client. The nature of the data in the GridView is that it can change from day to day per Client, but wouldn't need to be refreshed more frequently than that. The Page istelf only deals with one at a time Client based on a QueryStringParameter. My questions are a) how do I cache the DataTable so that a call to the DataBase isn't made each time Repeater item is bound and b) can I create/cache multiple DataTables (one for each Client) and let them live for day, checking for existence before calling the SQL stored procedure to regenerate the data?

Data Controls :: Determine Date By Subtracting Days From Current Date Dynamically From TextBox

Jan 17, 2013

in my asp.net_vb code web. there are 9 textboxes whcih is used for entering numerical/dates

first is lve.text in whicj numder is entered

second one is lvefrom.text

thirdone is lveto.text

when user fills (lve.text) 5 and enter 15 Jan 2013 in lvefrom.text then lveto.text should show 19 Jan 2013. i had posted this earlier and got reply which is mentioned below. this code below gives me 20 Jan 2013 instead of 19 Jan 2013.

tw text boxes lve.text (number filled) and lve from.text (date filled). when user enter a numder in lve.text and select a date fro date picker in lvefrom.text then lveto.text should show date selected in lvefrom.text + number of days in lveto.text (eg if number of days is 5 and date selected in lvefrom.text is 15 Jan 2013 then lveto.text should display 19 jan 2013. because the starting day is also counted in my case.

Protected Sub lvefrom_TextChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles lvefrom.TextChanged
Dim ObjLocDate As New Date
Dim IntLocDays As Integer
IntLocDays = Convert.ToInt32(lve.Text)
ObjLocDate = lvefrom.Text
ObjLocDate = ObjLocDate.AddDays(IntLocDays)
lveto.Text = ObjLocDate.Date.ToString("dd-MMM-yyyy")
End Sub

fourt tex box is pfx.text, fifth is pfx1.text, sixth is pfx2.text

when use filles pfx.text 3 then pfx1.text should display 12 Jan 2013 and pfx2.text should display 14 Jan 2013. these are the prefix for leave( as 12 to 14 Jan 2013 is prefix.seveth is sfx.text, eighth is sfx1.text and nineth is sfx2.text

when user fills sfx.text 3 then sfx1.text should display 20 Jan 2013 and sfx2.text should display.
