I have some asp.net pages that read and write cookie values. During the life cycle of a page it may update the cookie value and then need to read it again further in the code. What I've found is that it's not getting the latest value of the cookie until a page refresh. Is there a way around this? Here's the code I'm using to set and get the values.
public static string GetValue(SessionKey sessionKey)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
return string.Empty;
return cookie[sessionKey.SessionKeyName] ?? string.Empty;
}
public static void SetValue(SessionKey sessionKey, string sessionValue)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
cookie = new HttpCookie(cookiePrefix);
cookie.Values[sessionKey.SessionKeyName] = sessionValue;
cookie.Expires = DateTime.Now.AddHours(1);
HttpContext.Current.Response.Cookies.Set(cookie);
}

I have a page that shows statistics for users, this cannot be cached because each user has different statistics and there are many thus the real time query must be made.
What the way to avoid database server overload when user will click F5's to refresh or to ask different queries in short time intervals ?

I will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit  Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.Â

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:
