Cache or xml file

[ss mmm]

Is it better to cache a dataset on the webserver OR use a XML file on a server and maintaining a structure in the XML file that we populate accordingly when required The dataset has 10 datatables and the site could have more than 50 users at once instance Is it better to use the XML file stored on a server or Cache the dataset on the webserver considering that the application runs on a web farm I have to cache the dataset for the users to come back again to the same page and enter new values in the dataset ( something like adding stuff to a basket )

Thanks

Don't you have a database that you can use for this? It's more stable and much more scalable, which is important for a high load application.

Despite everything, the person most likely to be fooling you next is yourself.
