-		The FileCache class provide functionality for file and directory caching for the web module.
-		It can evaluate a folder, and save all file paths into memory.
-		Using this functionality can increase performance in certain scenarios, as the application does not have to use a syscall to evaluate whether a file exists or not, and also helps with avoiding directory traversal attacks, as relative paths are not going to be expanded by accident.
+		The FileCache class provide functionality for file caching and name and path sanitization for the web module.
+		It helps with avoiding directory traversal attacks, as relative paths are not going to be expanded by accident.
 		(A directory traversal attach would be if an application receives this get request: [code]server.net/../../../etc/passwd[/code], and it would result in success, if the app then returns the contents of the "passwd" file, which is outside of the root folder of the server.)
-		[FileCache] has a drawback for now, as it doesn't yet watch for changes in the folder, so if files change it needs to be manually refreshed.
-		It can also save contents of files into memory if needed using the [code]set_cached_body()[/code] helper method.
