Deployment Primer

• Simple transparency is not compatible with some older Web browsers when their

HTTP requests do not include information about the host.

• HTTP requests for servers that use a port other than the HTTP default port 80 are

redirected to IWSVA. This means SSL (HTTPS) requests are typically fulfilled, but

the content is not scanned.

• Do not use any source NAT (IP masquerade) downstream of IWSVA, because

IWSVA needs to know the IP address of the client to clean.

• A DNS server is needed for DCS to resolve the client machine name from its IP

address in order to perform a cleanup.

A Layer 4 switch can be used to redirect HTTP traffic to IWSVA. The HTTP Scanning

Service must be enabled in the HTTP Proxy mode.
