This programmer must also effectively "no cache" certain files from Google spiders. This job is of immediate importance.?
This is hosted on Unix servers which are shared. Program directories are searchable via the web. While most files and applications are password protected, there are back-doors and accessibity from this directory that need to be eliminated. In addition we have many files that are generated in PDF form for email transit. Since Google indexes PDFs this needs to be changed to password protected PDFs which are sent via email.
