I am maintaining a .NET 2.0 application that uses a System.Windows.Forms.WebBrowser to display reports from Reporting Services 2005. Caching is disabled for all reports on the server, and this seems to work as expected. The problem is that the WebBrowser control insists on checking Temporary Internet Files for a cached copy of the repor...
I've been reading a lot of articles that suggest putting a Memcached (or Velocity, etc) in front of a database is more efficient than hitting the database directly. It will reduce the number of hits on the database by looking up the data in a memory cache, which is faster than hitting the database. However, SQL Server has it's own memo...

Is there already such a solution? What do you think about that idea:...

I have some small sets of data from the database (mysql) who are seldom updated. Basically 3 or 4 small bi dimensional arrays (50-200 items). This is the ideal case for memcached, but I'm on a shared server and can't install anything. I only have PHP and MySQL. I'm thinking about storing the arrays on file and regenerate the file via a ...

So my solution was something like this: I took apache commons-pool library and used its StackObjectPool implementation for my remote ej...
In a Perl program I cache SQL request result to speed up the program. I see two common way to do that: Create a hash using the query as index to cache result, like suggested here Create a hash with but 2 index, first is the list of used table, second is where clause I today used the 2nd option because it's easier to clean the cache ...

I'm working on a .NET data logging application that needs to accept data from a large number of clients and store it in a database. The client sends a start event to the server and then sends heartbeat events, causing the last activity time of the data to be updated. I can't use an end event because the client app may be closed with no ...

In first one, I registered as new user using default membership provider. I closed this application, opened second one and ran it. In this application I was also logged in a...
I'm using ASP.NET Cache in my website and recently I've noticed that items in it are still being retrieved after the expiration time has passed.
