I am inserting and updating the image from html file upload to my gridview / insertion goes fine , but when i update the image by clicking on edit using onselectedindexchanged event of gridview, I fetch the image then change it with other image, with this simultaneously i rebind the gridview, in the beck-end everything goes fine it updates and replaces the image but in gridview it won't show after updated. I am using postbacktrigger on my submit button, but gridview won't refreshes, until and unless i click on address bar and press ENTER , or until i won't press CTRL+F5 to clear the browser cache.
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 created a custom 404 page and set its output cache duration to 7200 seconds (the pages themselves aren't updated more than twice a day, so I figured this was reasonable).
I ran into an error on the live side of things when I uploaded it, and I'm trying to debug and solve it. The problem is that I can't seem to figure out how to get rid of the cache itself, which definitely appears to be getting in the way. The reason I say that relates to my stack trace:
Server Error in '/' Application.
Input string was not in a correct format.
Description:

I've been trying to debug the ExtractURLComponents sub, and even commented out every line in it.
[Code]....
I'm still getting an error, even with every line of the sub commented out. So this is why I'm thinking it's got something to do with the cache. I tried clearing it with a different page using this:
[Code]....
I'm not sure if there's anything I'm supposed to do to clear the cache.
My 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?
How do I force a control+F5 (deleting cache) when updating an application? The users will not do this so I need to force this. Can we use some kind of flush method checking version or...?
I would like to reset/clear an item in the Cache, but without resetting the application or writing a specialized page just for this. ie, a non-programmatic solution.

Not sure if i'm posting in the right forum, if not, please move it...i have the following issue... I want to "disable" browser's back button. Seems it's not possible, but using cache.setcacheability and timing it, kinda disables the option of navigating back. I need this because in some pages of my webpage, i keep values in a Session variable so when a page loads, i need to check that variable, and, if navigating back, cant do that. I also "set cache to false" because if someone closes session, and i allow cache, someone else could handtype a url in that same pc and see the page without login (though if he/she tries to navigate through it will be kicked out because when loading a new page, i'll know that he/she is not logged) but i dont want to allow even that,
that's why cache is disabled. The problem is that loading over and over again my masterpage (header, footer, menu and stuff) is going to slow down the webpage, because every time there's a request, the page has to be sent again completely. So, is there something like a "mix" mode where i can allow cache just for a few things? If not, what's the best practice to achieve both things i'm trying: speed and security?
i want to clear history of user page after they sign out from their page manipulations.I googled it and found some ways with cacheability,but it doesnt work fine.
User X login as "user1" in web browser. Then user Y also login as "user1" also in another web browser. User Y got error message "Another user log in some account".
That is work as expected.
If X, close their web browser. Then try again to login in as "user1". X get also get "Another user log in some account".
So i trying debug then i found session is remove when web browser is close, but cache still remaining in web browser.
how to clear cache when user close their browser, (not tab).
I have a menu on my site that changes depending on whether the user is logged in or not. With browser caching, the menu "gets stuck" in either state and is confusing to users.They'll login, but the menu won't update because it's still cached in the unauthenticated state... and vice versa.How is this typically handled? Can we refresh the user's browser cache from our code? Or do I just not allow browser caching? (would rather use it, very nice bump in speed).UpdateHere's how I set client-side, browser caching in my asp.net mvc 2 app:
public class CacheFilterAttribute : ActionFilterAttribute { /// <summary> /// Gets or sets the cache duration in seconds. The default is 10 seconds.
I'm using an outside page to update an image in my system. When I'm redirected back to the page I've worked in, I still see the old picture. I don't see my changes until I press ctrl+f5.
