ICAP concentrates on leveraging edge-based devices caching proxies to help deliver value-added services. At the core of this process is a cache that will proxy all client transactions and will process them through web servers. These ICAP servers are focused on a specific function, for example, ad insertion, virus scanning, multi-AV scanning, content translation, language translation, or content filtering.

Off-loading value-added services from web servers to ICAP servers allows those same web servers to be scaled according to raw HTTP throughput versus having to handle these extra tasks. One web page could be streamed through virus-scan, content-filtering, and language translation servers, quickly.

This replaced original store-and-forward protocol with continuous streaming of content through many servers at once. To provide a feature called "content preview" that allowed the ICAP server to look at the first few hundred bytes of content before deciding to process the content or not.
