I have a page that deploys a user control to display an article. The page will show a different article depending on the ID parameter fed in via querystring, and there are many thousands of articles in our db. Here is the problem: I need to cache the user control to improve performance. But editors constantly need to go in and make changes/corrections, which they want to appear instantly on the site. Is it possible to clear the cache for a specific article only once it has been edited? ie for the request article.aspx?id=123? If so how would I do this? Otherwise, if the cache is cleared for all our content every time a single piece of content is edited, it will defeat the object of caching in the first place. I have tried using a cache key as recommended here: [URL] However, this apporach suffers from the drawback mentioned above. have also seen that you can set caching up to be cleared by changes to the db. However, the particular table concerned holds content for a number of other sites and would also have the same disadvantage.

I have a web form where most of the aspx markup never changes. Only a few controls change from time to time. As I have read through some articles it seems I have to create a custom control to enable partial page caching. Is there another way where I can cache all but a few controls?

I add cache to my application, I have a page which contains several User Control, my problem is I just want to cache the data returned from Controller, but not want to cache all the page content. Since one of my user control is login control, if I cache all the result, then it will behave incorrectly.
my problem is :
1.Is it possible to just cache the data returned from controller ?
2.If a page is cached, can I force a control in the page to be uncached ?

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.

I have an ASP.NET website in which the user has the Login/Logout functionality. There are some pages which are viewable only if the user is logged in. Now, after the user signs out, I noticed that the user is still able to see this restricted page on pressing the back button. I want to create the functionality such that once the user signs out, the page should not be viewable. How can that be done?
P.S I am not using built in Login controls in ASP.NET

i have 2 questions about output cache:1.is it just me , or does it seems that it is used only after the second time that the user reaches the webpage? if so, why, and how can i tweak it to my needs? my guess is that it wouldn't be logical to cache every time a user reach a webpage, but only when it happens enough times.2.i know that i can use "varybyparam" for using the output cache when the parameter doesn't change , but it seems that it would use the output cache even if there is no parameter , or if the specified paramter is not there. is there a way to overcome this?3.an old question that somehow marked as "answered" , yet i didn't solve : suppose i created a user control and i gave it values through the CTOR via the aspx file . is it possible to show the values from within the split/design mode? remember that i've talking about ASP.NET and not simply C# winforms . i write this because this question was on :[URL]and the answer that i got was for C# and winforms . i've tried to do the same for ASP.NET , but i've failed.

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?

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?

I have a server control that I developed which generates navigation based on a third party CMS API. Currently I am caching this control using the PartialCaching attribute. The CMS uses cache key dependencies to invalidate the cache when a user makes an edit, however in the case of my server control it does not get invalidated and the updated navigation will not show up until the cache expiration set by the PartialCaching attribute.Here is my two part question:
What is the proper way to programmatically cache a server control, without using the PartialCaching attribute, and adding a cache key dependency?
Is it possible to continue to use the PartialCaching attribute and add a cache key dependency?

I developed an ecommerce application.In this application (out of all other user products stuff ) use Sales to products
Here is simple demo:
http://clients.mantis.co.il/EcommerceDemo/
For example
Buy 20 products and the other 2 product with 50% off
And another example
Buy 1 product and the other cost 9.99$
And last example
Baying more than 600$ got 20$ discount
Course calculate this is not so simple, and the GET BASKET event can take time
I wondered what the best way to do it. My 2 options are:
1. Try to cache the user basket.Yes - because this calculate make just one time (until the user change and add product to the basket etc')No - because this object keep on the server, and if I take a situation that many user fill their basket I don't want the server work slower because the consequence of this decision.
2. Of course the opposite to call this calculate each time than its make slow the make basket event but this not "sit" on the sever and I am not afraid of crash the server.
