Squid is an Open Source proxy application that can also be used as a reverse proxy. The difference between a proxy and a reverse proxy is that a proxy delivers content from multiple webservers to one user, while a reverse proxy delivers content from one webserver to multiple users. For example, a normal proxy might be used to provide a degree of anonymity to a user or to access servers that would otherwise be blocked; the proxy would access many other servers on the user's behalf. On the other hand, one of the reasons for using a reverse proxy is to speed up the delivery of content to all visitors of a particular server. This article shows how to use Squid with eZ Publish to improve the performance of your website.

The US Department of Defense's Information Technology Security Certification and Accreditation Process (DITSCAP) is the standard Department of Defense (DOD) approach for ensuring that information systems operate at an acceptable level of security risk. The process is the same in all branches of the armed forces and all DOD agencies and applies to all unclassified and classified DOD Information Technology (IT) systems that collect, store, transmit or process information. DITSCAP standardizes and consolidates the activities that lead to the security certification and accreditation of IT systems. Successful certification and accreditation results in an Authority to Operate (ATO) that remains valid for a period of three years.
