I am using System.Web.Caching.Cache in an assembly used by my website.
I have set some key expiration (absolute expiration) to be 10 seconds (just for debugging).
I have also set a callback upon key removal.
The problem is that I see that the cache is getting refreshed after something like 20 seconds and not 10.
I am using HttpRuntime.Cache for this.
I would like to show a code sample, which can shed more light:
[code]....
What could be the problem ?

I have a lot of requests that read my Web Config file (eg. variable = WebConfigurationManager.AppSettings["BLAH"]). I am wondering... Do WebConfigurationManager.AppSettings read from disk each time, or is it cached in memory. If it's read from disk each time then I guess I will need to move the variable to a static variable so as to improve my app performance...

Is there any tool or way by which we can cache our pages after fixed time automatically instead of user to click link and then cache on server.

When I attempt to store the current time of 'DateTime.Now' in a column defined as time in a table within an SQL database, I get an error message that says: Cannot implicitly convert type 'System.DateTime' to 'System.Timespan'.
I have no trouble storing the current date of 'DateTime.Today' in a column defined as date, but this column will not also store time along with the date. The date column has properties that indicate it has a data and system type of date with a Length of 3 and a Numeric Precision of 10. The time column has properties that indicate it has a data and system type of time with a Length of 5, a Numeric Precision of 16 and a scale of 7. Did I define the time column incorrectly for storing the time of day?

I have some problems in database connection and wonder if I have something wrong in my code. Please review. This question is related: Switch between databases, use two databases simultaneously question.
[code]....
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. Cannot open database "db" requested by the login. The login failed. Login failed for user 'root'.

Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. make sure the user has a local user profile on the computer. The connection will be closed.
After I formated my system, When I run my website on local IIS databases, aspnetdb.mdf don't seem to work. But works fine on local Cassini (VS).
But this problem is only with one of my new website , rest everything work fine.
Does it have anything to do with SQL Managment Studio? I din't take any backup of master database and all.

In Linq the Timestamp column is represented as System.Data.Linq.Binary.
I dont know how to retirve date time value in "MM-dd-YYYY" format from this Linq.Binary

Details:
I am using visual studio 2005 on windows xp sp3. The website is stored on file system. I used subversion to checkout the code from the server.
Here is the issue:
When I run the application for the first time everything is fine. But when I makes changes in the application then I should just be able to see those changes by reloading the page in browser. But it's not happening. I have to stop the development server and re-run the application which will start a new instance of development server and now I can see the changes. This takes like 3-4 minutes and it's a lot of waste of time which I can't afford.
For my fellow developer who is here for a long time everything is just working fine. He can just modify the page and reload the page in browser to see the changes.
Reading some forums on web, I tried to clear the cache of my browser (IE, Firefox) and it's not working. So, it's not a browser's cache issue. It's related to cache in development server.
