C# - Caching Of WebConfigurationManager.AppSettings - Read From Disk Each Time?

Nov 28, 2010

I have a lot of requests that read my Web Config file (eg. variable = WebConfigurationManager.AppSettings["BLAH"]). I am wondering... Do WebConfigurationManager.AppSettings read from disk each time, or is it cached in memory. If it's read from disk each time then I guess I will need to move the variable to a static variable so as to improve my app performance...

MVC :: Output Caching And Query Dependency?

Sep 21, 2010

I plan to use output cache for my page and also specify sql dependencyi succeded in doing it the following way


Suppose if i want to implement a dependency on the sql query , i create an sqlcache dependency object and specify the sql command to it.Set the notifications .But how do i add this sqldependency to the output cache?For example: if i need to add a file dependency, i give something like Response.AddFileDependency ("filepath"); is there any similiar command available for sqldependency as well? I'm confused about this because, most of the examples i've looked into, does a cache.insert , which defeats my purpose as it's object caching and not output caching. In a nutshell, is it possible to attach a sqlcachedependency to o/p cache inside the controller action

Web Forms :: User Control Output Caching?

Jan 11, 2010

I have a user control (say PricingGrid.ascx) which generates a pricing grid on a given product's page. I pass the user control 2 parameters : currencyId and productId. The user control has output caching specified by


I am adding PricingGrid.ascx to my page programatically, i.e. using LoadControl [URL]If the user changes their currency and refreshes the page, the cached version of their original currency is still showing, until the 60 seconds expires. Is there any way to force the page to check :1) Does a cached version of PricingGrid.ascx with their new currency exist?2) If so, retrieve that version, and if not, create that version.If I output all the keys in the Page.Cache object on PageLoad, I'm not seeing my user control in the output.

Output Caching In HTTP Handler And SetValidUntilExpires?

Jun 8, 2010

I'm using output caching in my custom HTTP handler in the following way:

public void ProcessRequest(HttpContext context)
TimeSpan freshness = new TimeSpan(0, 0, 0, 60);

It works, but the problem is that refreshing the page with F5 leads to page regeneration (instead of cache usage) despite of the last codeline:


UPD: Seems like the cause of problem is that HTTP handler response isn't caching on server. The following code works well for web-form, but not for handler:


Are there some specifics of the caching the http handler response on server?

MVC - Enabling Caching Of The Compressed Page Output?

Sep 30, 2010

I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.

Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.

This question really could apply to regular as well.

How To Use Partial Caching With Dynamically Created Controls

Nov 24, 2010

I have a control declared with PartialCaching attribute, like this:

[PartialCaching(60 * 60 * 12)]
public class MyControl : Control {
// control contents ...

but I create it in code, using new keyword. The problem is that if the control is in cache I must not create the control again the next time, but I need to add the control to the page hierarchy, otherwise nothing is going to be rendered. What I need in pseudo-code is something like this:

if (myControlIsCached) {
var ctl = ???; // something that represents the cached control
// e.g. could be: new LiteralControl( myControlCachedData ) [code].....

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.

Web Forms :: Output Caching Doesn't Work With Rout Handler

Apr 22, 2010

I am trying to use output caching on my .net pages but it is not working when I use Route handlers to redirect request to actual page, but it works when I call the page directly.

also one more weird thing is that when I am debugging and using .net instance of IIS http://localhost:64293/test it is working, but when I deploy it and try to call the page it is not caching i.e. http://www.mydomain/test(but it works if I call the page directly)

I am using VS 2010, IIS 6.0, .net Framework 4

aspx page code is :

<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile="~/Site.master" Title="Not Found" %>
<%@ OutputCache Duration="300" VaryByParam="*" Location ="Server" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
litPageTitle.Text = "<br/>Datetime: " + DateTime.UtcNow.ToString();

my global.asax.cs code is

public static void RegisterRoutes(RouteCollection routes)

Running IIS7 In Classic Mode Does Affect MVC Output Caching

Feb 25, 2010

I have a need to run an application in classic mode for backwards compatibility with a specific application, and am trying to understand what kind of impact that will have on the performance of an MVC application that is running on the site. If we put a few static file maps (for .js, .css, .png, etc) above the ASP.NET wildcard map to reduce the amount of processing by the ASP.NET handler, will we be approaching the integrated mode in terms of performance?

The thing i'm primarily concerned with is any effect this might have on output caching. I understand that integrated mode might (?) allow for the output cache to handle non ASP.NET content, but that isn't really a concern. We're more interested in ensuring that the MVC application has full use of the output cache. Empirically i've found that the two configurations operate on par when things go well, but if the page references resources that are not available, the integrated mode tends to fail much more quickly than the classic mode (e.g. 500 ms vs 10 seconds), reducing 'hang time' on the page load.

Render Output To String - Response.Flush Breaking Page Caching

Feb 3, 2010

I have some code that is used to replace certain page output with other text. The way I accomplish this is by setting the Response.Filter to a Stream, Flushing the Response, and then reading that Stream back into a string. From there I can manipulate the string and output the resulting code. You can see the basic code for this over at [URL] However, I noticed that Page Caching no longer works after the first Response.Flush call.

I put together a simple ASP.NET WebApp as an example. I have a Default.aspx with an @OutputCache set for 30 seconds. All this does is output DateTime.Now.ToLongTimeString(). I override Render. If I do a Response.Flush (even after the base.Render) the page does not get cached. This is regardless of any programmatic cacheability that I set. So it seems that Response.Flush completely undermines any page caching in use. Why is this?

extra credit: is there a way to accomplish what I want (render output to a string) that will not result in Page Cache getting bypassed?

ASPX Page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCacheVsFlush._Default" %>
<%@ OutputCache Duration="30" VaryByParam="none" %>
<%= DateTime.Now.ToLongTimeString() %>

Code-behind (Page is Cached):
protected override void Render(HtmlTextWriter writer)
Code-behind (Page is not cached):
protected override void Render(HtmlTextWriter writer)
Code-behind (Page still is not cached):
protected override void Render(HtmlTextWriter writer)
