Explicit Deployment
This deployment involves explicitly configuring all client web browsers to use the Web Appliance, although you can also do this centrally by using distributed Active Directory Group Policy Objects (GPO).
- Inspects HTTP, HTTPS, and FTP over HTTP traffic.
- All clients require configuration (may be done centrally; see the “Configuration” section below).
- If the deployment fails, all clients must be reconfigured (may be done centrally; see the “Configuration” section below).
Operation

- Users’
HTTP, HTTPS, and FTP over HTTP requests are passed to the Web Appliance
.
- The Web Appliance
assesses URLs, blocks disallowed requests, checks if allowed URL requests are currently cached, and passes URL requests that are not cached through the firewall
to retrieve them from the internet
.
Note Port 80, port 443, port 20, and port 21 requests from usersare blocked at the firewall
; URLs are only accepted by the firewall
if they are from the Web Appliance
.
- The Web Appliance
receives any new pages or files and caches them; it passes the pages or files of allowed requests back to the users
.
- The users
receive only safe and allowed pages and files or a notification page.
