View 2 RepliesMVC :: Clearing Output Cache?
Jun 26, 2010 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?
WCF / ASMX :: Web Service Image Cache Clearing?
Jan 26, 2011Users can edit images downloaded from my site and then upload them back using a WCF Web Service. The problem is when users go to view images, they often do not see the latest versions because of caching. I'd rather not turn off the cache because it substantially reduces bandwidth. Is there a way to have the Web Service perform some action upon an upload to notify the next web client call that the image has changed?

View 1 RepliesClearing Page Cache - Show Correct Status Always?
May 16, 2010I use this type of cache code on my pages
<%@ OutputCache Duration="60" VaryByParam="*" VaryByCustom="browser" %>
An issue by example. I have a page with the asp.net 2 (MSVS 2005) membership menu controls <asp:logonview etc on them. This control show different menus depending on if the member is logged on or not. I am using forms cookie authentication. The sequence of events. Page1 has the above cache settings and a logonview menu control on it. I am not logged on. I goto Page1. I view the page, and the logonvew control shows the button to logon. So correctly it has not detected a membership cookie and shows the logon button. I log on. I go back to page1, yet the logonview has not updated the menu for the newly logon status, as the page is sourced from the cache. I have to wait 60 seconds before the page can be rendered correctly. When the page is updated for logon status, the menu button for logon does not show, it should show Welcome Member Joe Bloggs. How can all pages cache be cleared when a log on happens, so there is not cache limbo, and the logonview menu control shows the correct status always?
Caching User Control And Clearing That Cache Programmatically?
Jul 13, 2010I'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.
Clearing Cache In Internet Explorer Using "master Pages"?
Jan 6, 2011In my asp.net web application I would like to clear all cache upon login when I click the back button in IE.

DataSource Controls :: SQLCacheDependancy Invalidates Cache Immediately SQL Server 2005?

C# - Optimal Way To Cache Time Of Day Description?
Mar 30, 2011What is the best method to cache the following? I am creating an intranet web application template that will display the message, e.g., Good Morning, Justin Satyr! near the top of my master page header. Obviously, I will have to determine whether to show Morning, Afternoon or Evening. For clarity, my code is below:
string partOfDay;
var hours = DateTime.Now.Hour;
if (hours > 16)
{
partOfDay = "evening";
}
else if (hours > 11)
{
partOfDay = "afternoon";
}
else
{
partOfDay = "morning";
}
I do not want to re-determine this on each page load because that seems moderately redundant and because I have to poll a SQL server to retrieve the user's full name. What is the best way to cache this nformation? If I cache it for the length of the session, then if the user begins using the application at 11:00 AM and finishes at 3:00 PM, it will still say Good Morning. Is the best thing to do simply re-determine the M/A/E word each page load and cache the person's full name for the session? Or is there a better way?

System.Web.Caching.Cache Doesn't Seem To Refresh Itself On Time
Jan 27, 2011I 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:

Cache Sharing - Between Different Users Accessing The Site On Different Computer At The Same Time
Jul 21, 2010I have an ASP.Net 4.0 web application which very frequently loads data from the database and does heavy calculations on it. I want to cache this loaded and prepared data in a central cache that can be accessed by every user and computer who uses the application.
Simple use-case:
User 1 accesses webpage, cache is empty, data is loaded/calculated, data is cached
User 2 accesses webpage, cache contains data, data loaded from cache
User 3 accesses webpage, cache contains data, data loaded from cache
User 1 reloads webpage, cache contains data, data loaded from cache
Cache expires
User 3 refreshes webpage, cache is empty, data is loaded/calculated, data is cached
I know that ASP.Net has a built-in cache mechanism. What I don't know is whether it can be shared between different users accessing the site on different computer at the same time. I would also like to know how the system behaves in a web farm environment.

View 5 RepliesInserting Records From Multiple Computers In The Same Database At The Same Time In SQL Server 2005?
Nov 12, 2010I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
