Globule is a third-party module for the Apache Web server that allows a given server to replicate its documents to other Globule servers. It takes care of maintaining consistency between the replicas, of monitoring the servers, and of automatically redirecting clients to one of the available replicas. Globule also supports the replication of PHP documents. It runs on Unix and Windows systems.

Because of the limitations of HTTP, it is difficult to monitor the status of files as they are uploaded via HTML forms. While other programming languages have built-in methods to monitor file uploads, PHP does not. This article shows how to implement such a solution in PHP. In order to achieve this, the APC (Alternative PHP Cache) PHP extension is required, as well as PHP 5. Specifically, APC 3.0.13 or newer and PHP 5.2 or newer are required for the code in this article to work. We will cover installation of APC in the next section. It is assumed you already have a working PHP 5.2 installation.
