Introduction:

A browser temporarily stores files that make up a webpage locally, because it is faster to retrieve and display information from the local hard disk, rather than making a full request from the server.

For example, every time the client browser makes a request for an image, the browser can retrieve this image from the local disk, which is faster than downloading it from the server.
During this process, the caches (locally stored temporary files) can become corrupted from events such as bad or incomplete page loads. If the webpage rendering is intermittently or 
inconsistently loading, take the following steps to rule out a caching issue.

In CA PPM, it is best to the following steps to perform a complete cache flush to resolve the issue.
