You may not write your own scripts or programs or applications, or install freeware or shareware, or commercial scripts or programs or applications in your website directory on the development web server or main (live) web server.
All requests for programs or scripts (including CGI, Perl, PHP, etc.) or applications to be installed on a web server must be approved and managed by the Information Technology Department. Installation and configuration will be performed by the Information Technology Department. It may be necessary for your department to purchase a web server to run the software.
