Clearing Page Cache - Show Correct Status Always?
May 16, 2010
I 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?

I have MVC 2 site, and I.E is cacheing word documents linked on my site. I know there is a way to clear cache before every action in the controller. But for these links i am not using action, i am just creating regular href links.. Is there anyway i can clear the cache?

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?

Users 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?

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.

How can I configure ASP.NET/IIS to show custom error pages (i.e. a nice friendly error page), but to still return a 404/500 status code so that google does not try to index the page? I have tried setting the Response.StatusCode to 404, but then the nice error page does not show anymore.

In my asp.net web application I would like to clear all cache upon login when I click the back button in IE. I have tried various different ways but after I click the back button and then click the forward button it goes back to the submission aspx page with the same cache values. I am using master pages as well, if this makes any difference.

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 created a asp.net website, that we are going to deploy at India. All client of this website would be from SWEDEN.
This site have option (last login date time) at user's dashboard after successfull login.
Now my problem is that if application is deploy at India and user loggedin from SWEDEN then user is able to show only server date time which is of India.
My Steps are as following
1. User logged into site first time at 10 AM(server time), surfing starts...
2. Logged out at 10:30 (server time)
3. Application store server datetime in database.
4. Next time user come, application will store same date and time from database as last loggin datetime.
How can i store SWEDEN date time in database when user logged out from site, it will in future grow to other country also.

A strange issue.. and probably some key thing I am missing...I am using the MS Enterprise Library version 5.0.. specifically the cache engine.
I have a website where from a certain page I do the following:
Cache some values I need for the next page or two..
Go off to another site - actually a payment site..
That payment site returns to my site..
I retrieve the cache values to show..
Ok, I know I am going to probably get shot here.. but apparently on the "odd" occasion, a user says they see the details from a previous user?
I thought when you cache an item (session, cache or whatever), this is only relative to the users session?

I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person.
Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default.This is my code once they choose a user:
Code:
Namespace prog.Controls
Partial Public Class progReportGrid
etc....
[code]...
So when the page loads and i choose a user, it tells me that strID = nothing and i know it at least should have 00007700000 in it?

I have an ASCX component that has a lot of javascript declared in a script tag in the ascx itself. I can set breakpoints, and the debugger stops as it should, but the text that is highlighted in the debugger as the "current line" is nowhere near the actual javascript (it is much higher in the rendered file than it should be). I can "wing it" for one or two lines with the real code side-by-side with the "false" line of execution, but I lose all the hover abilities and everything else that makes javascript debugging useful.
I have tried putting the script at the top of my ascx file, but to no avail. I've tried not setting a breakpoint until the entire page is rendered, so that I have to scroll all the way to where the actual lines of code are, and the debugger still stops somewhere way above it.

I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).
Response.Redirect("menu.aspx", False)
