How to avoid IIS reset the application pool in the server

Most of the time when a user enter to the site, it take a lot of time to load the first time to the page, after the page works well for user and other users in other networks. I created a cache that is store in 开发者_开发知识库an application variable to reduces the access to the data base and increase the performance but It is reset when the application pool is restart. I can´t have access to the IIS application pool on the server because it a server that share different applications. How can I do to change the time that the application pool is reset?

You can't (I'm sure) because this is controlled by IIS itself not code. What can you do is prime the cache on application start though
