Caching User Controls On Site?
Feb 15, 2012
I have been working on a site recently that relies heavily on user controls.
With the site nearly complete we are now looking to improve efficiency with some caching.
I have been looking at a number of options. In some cases a simple varybyparam fits the bill. However some user controls don't suit this model for whatever reason.
This sent me down the line of PartialCaching where I vary the cache by property.
This seems to work a treat if I declare the property in my markup, ie <uc7:JustPublished ID="JustPublished1" runat="server" categoryid="101" />
however if the control sits on a page that has a number of variants and I set the property in the codebehind eg categoryid = 101 it does not vary the cache.

I have a page with a number of user controls, In one of my user controls I have a button event. I turn on output cache for the user control that has the button and vary by control using the ID property of a hidden field control in the user control. whenever I turn on the output cache my button event doesn't fire.

I have a requirement where I have to transfer a user from Web Site 1 on Server A to web Site 2 on Server B.
On Web Site 1, I have to provide controls to enter user id and password and which have to be validated on Web Site 2 on server B, after validating them I have to redirect the user to Web site 2.
what is best way fo doing it. code examples are greatly appreciated.
Note: On Web Site 2, user login functionality is already existing and it is provided by ASP.Net login control, am not sure how to handle the user login process from two different places.
or is it the best way to move Web Site 2 from Server B to Server A so that, the same login controls will be shown using Iframe on Web Site A.

it is possible to cache an ASP.NET UserControl on the Client.
I have an User Control that queries a DB and renders a GridView. It must be on the Client because the query results vary from user to user (by the User.Identity.Name).

In our .aspx pages we have user controls each control has a Sql query to fetch data. The caching mechanism to be followed says that fragment cache all the user controls and invalidate the cache based on the respective queries of the user control.How to proceed to add a query dependency to fragment cached user control?

I have an asp.net (VB 2008) portal site. This is the only public page, all other pages are individual for each user after login. The portal site (and all others of course) is multilanguage, depending on users browser settings. Could I enable caching on the portal site? I don't have a language parameter given in the URL explicit. Could I set up the cache to create different caches depending on the users language set in the browser?

I have a user control (.ascx file). I simply put this tag in the page declarations section:
<%@ OutputCache Duration="60" VaryByParam="none" %>
It is not caching. The control makes a call to SQL and displays some information. I tested it by changing a value in the database and refreshing the page. The control keeps making a call to the database eventhough I have the duraction set to 60 seconds. Am I missing something? Do I need to add code in the Page Load event?

What's the best way to cache web site user data in asp.net 4.0? I have a table of user settings that track all kinds of user or session specific stuff like the state of UI elements (open/closed), preferences, whether some dialog has been dismissed, and so on. Since these don't change very often (for each user, anyway) but are looked up frequently it seems sensible to cache them. What's the best way? These are the options I've identified...
Store them in HttpContext.Current.Session directly (e.g. Session["setting_name"]) Store them in HttpContext.Current.Cache Use a global static dictionary, e.g. static ConcurrentDictionary<string,string> where the key is a unique userID + setting name value Store a dictionary object for each session in Session or Cache What's the most sensible way to do this? How does Session differ from Cache from a practical standpoint? Would it ever make sense to store a dictionary as a single session/cache object versus just adding lots of values directly? I would think lookups might be faster, but updates would be slower since I'd have to re-store the entire dictionary when it changed.
What problems or benefits might there be to using a global static cache? Seems like this would be the fastest, but I'd have to manage the size. I could just flush it periodically if it hits a certain size, or keep a cross reference queue and remove things oldest first when it gets to a certain size. Does this make any sense or is it just trying too hard?

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
[Code]....
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.

I have a page which contains a user control. The structure of the page is as shown below:
Incase your not able to see the above image, check it at [URL] Now, apart from the contents of the UserControl, I'd like to cache the entire page. I tried using the OutputCache attribute in the .aspx page, however it caches the contents of the UserControl as well.

My asp.net app is heavily using user controls and is high load; my concern is that loading user controls for every request (Page.LoadControl(controlPath)) is sub-optimal at best. I was thinking of caching an instance of loaded user control in HttpRuntime, but I don't know how's it going to behave when multiple connections (threads) will try to fetch it from the cache and modify properties - I guess trouble is waiting there. Any good way to optimize user control loading?
Again, I am talking about caching user control, not it's html output (which it makes no sense caching as it's [html output] going to be different every time you use it)

have an ObjectDataSource with the following configuration:
[Code]....
And the 'Select' parameters will aid in making a 'unique' combination per user selection to populate the GridView it is bound to:The problem that is occurring is that GridView search results are indeed cached, but the cache is a little too public and shared between all users currently running the application. So if user1 creates a search that populates the GridView with 100 results based on some unique dates and CategoryID, and then user2 in a separate browser does another search with different dates and a different category

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 a custom handler which captures user's book mark entry. To debug this handler, i have created a file "test1.txt" in code behind which saves the user entry. After the debug, i removed the text file (test1.txt) then re-complied the web app and deployed new DLLs for the site. But, the site is still looking for test1.txt file. i dont know how to confirm if the handler is really removed from the new DLL. Also, looked at the handler code behind file and didn't find any entry with test1.txt. So,

I am looking for an implementation similar to that of what is seen on banking sites. If a user comes to the site I want them to have to pass some form of registration IE (answer a question or enter in some key). If the user closes the browser and comes back to the site again from that machine they would just be able to provide login credentails to get in.
I am not sure if this is accomplished in ASP.NET by a cookie or what type of implementation.

I have an application in which a user can choose from different (learning)groups. User has only access to registered groups. When the user enters the site, he can choose (in a dropdown) which group he wants to see, so the complete site filters content related to that group. So every controller needs to access this global "group" object.What is the best way to do this in ASP.NET MVC? I've thought about a BaseController or ActionFilters. Is there any other best practice?I've build a WebForms application and there I used a BasePage so that any other page has access to the group.
