ASP. NET cache processing instance

ASP. NET cache processing instance

This example describes the ASP. NET cache processing class. Share it with you for your reference. The details are as follows:

ASP. NET cache processing class.

Usage:

Just copy this code into a new class file (. cs) and add it to your ASP. NET website. one thing to keep in mind is that data stored in ASP. NET Cache can be accessible implements SS all sessions. so when creating a cacheID for the object to be stored, it must be unique (or it cocould be overwritten ). I usually store the unique cacheID in the session and then use that to referrence the cacheID. (e.g. cacheHandler. write (Session ["MyCacheData"], myData );)

The Code is as follows:
