On our website we use standard asp cache with duration set to 5h.
It works fine, but sometimes the publisher add some special content that need to be showed impatiently on many different sub-pages (example some promoted article).
That's what I need to do it's easy to use page like this:
[URL]
I want to clear SERVER SIDE CACHE.
I need to enable caching in my asp.net application, but I do not want to use the webserver's memory for holding cache objects. If I add the page directive for output caching will the page be stored in the asp.net cache object?
View 2 RepliesYou know I have the way to Cache the data I've got from the SQL Server over data caching. In addition I can output cache web user controls.Whats about a web user control contains data from a SQL database? Does it make sense to cache the data and also cache the control?What is the best solution for the combination of these two components?
View 1 RepliesI have a class that is creating an instance of StreamReader to an xml file on the local filesystem.
It may be possible that this same file is requested multiple times per-second.
I was wondering whether I need to manually add this file to the System.Web.Cache and read it from there, or whether Windows itself is clever enough to cache the item itself so that it 'knows' when ASP.NET requests this file the second/third etc time that it doesnt have to do a disk seek/read operation and pulls it from its own cache?
This article: http://dotnetperls.com/file-read-benchmarks seems to back this up, but this: article:
[URL](although not discussing from a performance perspective, and maybe for other reasons entirely) lists how to add a physical file to the cache.
How can I manually clear ASP.NET server cache related to a give application/web site like what can be done on IE to clear browser cache for a give domain? BTW, I am using II7.
View 2 RepliesI'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting
<clientCache cacheControlMode="DisableCache" />
in the relevant <location> tag in web.config
If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?
I'm running an ASP.NET MVC website where several page controllers are decorated with an output cache attribute like:
[OutputCache(Duration = someduration..., VaryByParam = "*")]
These are typically forms where some lookup data are drawn from a database. These data change rarely, so the cache duration is typically set to 24 hours. Anyway, my question is: when the sql server is updated with new data in this area, is there a way of forcing such pages to "refresh" rather than keeping the cached output? Or if this cannot be done, is there at least a way of clearing the whole cache for the website?
I have a site that dynamically loads website contents based on domain host name, served from IIS7. All of the domains share a cached collection of settings. The settings are being flushed from the cache on almost every page request, it seems. This is verified by logging the times at which the Cache value is null and reloaded from SQL. This codes works as expected on other servers and sites. Is it possible that ASP.NET Cache is being stored separately for each domain host name?
View 3 RepliesI've got a website that has a number of host headers. Depending on the host header, the results are different - both visually (theme'd) and data.
So lets imagine i have a website called 'Foo' - that returns search results (original, eh?).
Now, the same code runs both sites. It is physically the same server/website (using Host Headers) :-
[URL]
And the data is different for the same search result, based on the host name (ie. us results for [URL] results for [URL]
SO .. if i wish to use OutputCaching .. can this be handled / differ by the host name?
Suppose i have an controller action that i would like to output cache.
public class HomeController : Controller
{
[OutputCache(Duration=10, VaryByParam="none")]
public ActionResult Index()[code]....
I need to dynamically set dependency to an external file inside the code. How can i do that?
I have different urls that points to the same code
www.url1.com
www.url2.com
I need to use the cache, but if the asp net cache is enabled when someone access to www.url1.com next person accessing www.url2.com could get the previously cached data (www.url1.com)
I need to have ALL caches activated except this one.
I implemented : <%@ OutputCache Duration="43200" VaryByParam="none" location="Server" VaryByCustom="RawURL" %>
I have got a sitemap.xml with all url(about 12000) possible in my site.
I would now if it's judicious to create an application that will parse my sitemap in
order to request all url?
The Goal is caching all my web site to increase velocity.
I precise my question :Each page take about 10 sec to be created and the cache duration and cache duration is 12 hours
IIS7, WINDOWS WEB SERVER 2008, ASP.NET 4.0 Does the output cache work when using webgarden?
View 1 RepliesMy web client requires client-side output caching since it makes use of its own Back and Forward buttons (which basically just call the browser back/forward buttons).
The issue I'm having, however, is (of course) when the user signs out of the app. The client-side output cache remains so anyone can click the "back" button and it appears to be signed in again. I've researched a few solutions, but most involve server-side output caching or no output caching at all.
I've had success with server caching and HttpResponse.RemoveOutputCacheItem, but unfortunately I need the client side caching.
Is it at all possible to clear this client side output cache upon logging out?
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.
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.
UserControl: How to set Output Cache duration programaticaly?
View 2 RepliesI want to use an Enum value for the types of VaryByCustom parameters I will support, is it possible to do this?
I tried setting it in the page itself
<%@ OutputCache Duration="600" VaryByParam="none"
VaryByCustom='<%=VaryByCustomType.IsAuthenticated.ToString(); %>' %>
But this returned the entire literal string "<%=VaryByCustomType.IsAuthenticated.ToString(); %>" inside my global.asax is there any way to do this either on the page itself or from the codebehind? Or is this just something I have to accept is purely magic strings and nothing I can do to add type safety to it?
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.
[code]....
It's great to be able to output cache child actions, but how do I invalidate that cache?
I've been trying to use [Code]....
I wrote a Simple Control, that implements ScriptControl. This is holder for JQuery framework:
/// <summary>
/// Generic control with client behavior handled via jQuery
/// </summary>
[code]...
I create a menu control in a user contol, named as RightUserrControl.ascx.
and i kept this RightUserrControl.ascx in nearly in 200 pages.
every thing is working fine , but when ever i am going to any page the page loading is very slow, nearly each page is taking 1 minute to load.
set caching for the user control, if this is the case , do i need to declare output cache in all 200 pages or is there any alternative way to resolve this issue.
I have set the output cache for 5 pages(5 minutes)
I want to clear all these pages from cache on some nutton click
I have an ASP.NET master page which references a #include file as follows:
<!--#include virtual="/includes/scripts.inc"-->
I have modified the file /includes/scripts.inc but the changes do not show up in pages. What needs to be done so modifications will be reflected? I need to avoid the following: restarting the server restarting IIS modifying web.config (doesn't appear to have any effect)
pretty much anything that causes the app domain to restart Any other options? Is there a setting which affects how long IIS caches #include files?
I'm working on an ASP.NET application that accesses Team Foundation Server 2010 and creates new work items. The application is running in the DefaultAppPool, using NetworkService as the identity. I'm getting the error below:
[UnauthorizedAccessException: Access to the path 'Cachev10' is denied.]
[code]....
We were able to work around the issue by turning the Cache folder into a network share and giving NetworkService full access to the share. I'd prefer not to have to do this, but it seems to be working correctly now.
