All rights reserved. ## ## What is RECC? • Remote Execution Caching Compiler (RECC) Open source build tool that wraps compiler commands and optionally forwards them to a remote build execution service Encompasses the capabilities capabilities of both ccache and distcc ☐ Supports remote linking and caching ## • Designed to share caches across diverse toolchains Works with many compiler toolchains (GCC, Clang, Solaris CC) o Supports

filter can be optionally inserted at a given point in the filter chain to provide fine control over caching. mod cache can now cache HEAD requests. |Where possible, mod\_cache directives details. ## Caching Guide The Caching Guide has been rewritten to properly distinguish between the RFC2616 HTTP/1.1 caching features provided by mod cache, and the generic key/value caching provided by by the socache interface, as well as to cover specialised caching provided by mechanisms such as mod file cache. # Module Developer Changes ## Check Configuration Hook Added A new hook, check_config
