+Artifactory expireFileInRepos User Plugin
+====================================================
+
+An implementation of the beforeDownloadRequest execution point. This
+plugin causes artifacts (including binaries) to expire and be re-cached when downloaded from a remote/virtual
+repository.
+
+## Features
+
+To use the plugin, modify the script by adding the names of the repositories you wish to expire artifacts in. 
+The names are to be added to the list 'reposToExpire'.
+Note: using this plugin, when downloading artifacts from virtual repositories - artifacts are expired and served from 
+the source repo for all underlying repos
+
+## Installation
+
+* Place script under your plugins folder at `${ARTIFACTORY_HOME}/etc/plugins/`
+* Restart your artifactory instance or [use the API to reload plugins][1]
+
