The following section describes how HTTP, SMTP, POP, and FTP connections operate in these
cases:
•

•
Internet Gatekeeper performs virus scanning

5.1.1 HTTP Connection

• Without virus scanning
The web browser connects to the web server directly and fetches the page.
• With virus scanning
When virus scanning is used, Internet Gatekeeper stands between the web server and client and
operates as a proxy server for the web browser. The web browser connects to the web server
through Internet Gatekeeper. The web browser retrieves pages after they have been scanned for
viruses. Internet Gatekeeper connects to the appropriate web server based on the URL that has
been requested from the web browser.
