Caching asp.net pages
<p>I am bulding an app and I tried YSlow and got Grade F on most of my practices. I have loads of jscript that am working on reducing. I want to be able to cache some of these because the pages get called many times.</p>

<p>I have one master age and I wanted to cache the scripts and css files.</p>

<p>How do I achieve this? 
Are there any recommended best practices?
Are there any other performance improvements that I can make?</p>
