Question

I am currently working on a large-scale website, that is very dynamic, and so needs to store a large volume of information in memory on a near-permanent basis (things like configuration settings for the checkout, or the tree used to implement the menu structure).

This information is not session-specific, it is consistent for every thread using the website.

What is the best way to hold this data globally within ASP, so it can be accessed when needed, instead of re-loaded on each use?

Answer 1

Any AppSettings in web.config are automatically cached (i.e., they aren’t read from the XML every time you need to use them).

You could also manually manipulate the cache yourself.

Edit: Better links…

• Add items to the cache
• Retrieve items from the cache
• Caching Application Data
