/cfg/ssl/server <id> /http HTTP Settings Configuration 109
Specifies how the virtual SSL server handles the optional HTTP-X-ISD
header. This header can be used for debugging purposes when end to end
encryption or load balancing of backend servers is performed by the VPN
Gateway. When added, the extra HTTP-X-ISD header contains information
about the IP addresses of both the VPN Gateway that initiated the request
and the responding backend server, the internal index number of the
responding the backend server, whether connection pooling is enabled, the
load balancing type and metric, and finally, whether end to end encryption
was performed.
Example of an added HTTP-X-ISD header:
HTTP-X-ISD: 192.168.128.25 192.168.100.1 index=2; pool=on;
lb=all-roundrobin; type=http-https
Valid options for the addxisd command are:
•
on: An HTTP-X-ISD header is added to the client request.
•
off: No HTTP-X-ISD header is added to the client request.
The default value for the addxisd setting is off.
Specifies how the virtual SSL server handles the Front-End-HTTPS
header. When using Outlook Web Access (OWA) for Microsoft Exchange
in combination with the VPN Gateway, the virtual SSL server must be
configured to add this extra header. The Front-End-HTTPS header enables
the receiving OWA server to transform embedded HTTP URLs in a correct
manner.
Valid options for the addfront command are:
•
on: An extra Front-End-HTTPS header is added to the client request.
•
off: No extra Front-End-HTTPS header is added to the client request.
•
anonymous: No action whatsoever is taken regarding the
Front-End-HTTPS header.
•
remove: The Front-End-HTTPS header is removed, if present, from the
current client request.
