What Is Caching? ISA Server caching stores a copy of requested Web content in the server memory or on the hard disk ISA Server caching provides: Improved performance — information is stored on the computer running ISA Server Reduced bandwidth usage — no additional Internet network traffic ISA Server caching scenarios include: Forward caching — Internet Web servers Reverse caching — internal Web servers

Lesson: Configuring General Cache Properties Caching Configuration Components How to Enable Caching and Configure Cache Drives How to Configure Cache Settings
Caching Configuration Components Component Explanation Define cache Enables caching by configuring a cache drive for storing the drives cached content Configure Modifies the default TTL and caching types of cached content settings Configure Enables unique caching policies caching rules for specific Web content Configure Enables the prefetch of content content before clients request the download jobs content
How to Enable Caching and Configure Cache Drives Caching is disabled by default on ISA Server 2004. When you enable caching, ISA Server creates a file with an initial size equal to the size you chose for the maximum cache size on the hard disk
How to Configure Cache Settings Configure Configure caching of negative objects caching with undefined TTL Configure response to request for unavailable Web site Configure memory used for caching

Lesson: Configuring Cache Rules What Are Cache Rules? How to Create a Cache Rule Managing Cache Rules
What Are Cache Rules? Cache rule options Default cache rule Define the destination Applies to all Web set that the rule content applies to Define how content is Returns non-expired returned to the user content to the user Define whether content Caches the default is stored in the cache cacheable objects Define whether to Enables caching of both cache HTTP, FTP, or HTTP and FTP content both types of content Does not apply any size Define the maximum restrictions to cached size for cached objects objects Define whether to cache Caches SSL content
How to Create a Cache Rule Cache Rule Configuration Options Wizard Page Use destination sets to define the Cache Rule Web content that this rule applies Destinations to Defines how ISA Server responds Content to client requests if the content is Retrieval or is not in cache Defines the types of content ISA Cache Content Server will cache Cache Defines maximum size for Advanced caching objects and SSL response Configuration caching HTTP Caching Enables and configures TTL settings for HTTP content Enables and configures TTL
Managing Cache Rules Managing cache rules includes: Modifying the cache rule configuration after creating the rule Modifying the cache rule order to evaluate cache rules for specific Web sites before cache rules for all Web sites Disabling or deleting cache rules that are no longer required Exporting the cache rule configuration before modifying the cache rules in case the modification is not successful
