IP Address:
Add an IP address to the current farm configuration. The IP address can be the same as long
as the port number does not duplicate any existing IP/port combinations.
Label:
The label is displayed on the column to the left of the corresponding IP addresses in the main
status screen. Although labels can be anything, it is better to have meaningful and unique
label for each farm. The label field is also used as the host name in “HOST:” MIME header to
when checking HTTP servers. The “HOST:” MIME header is essential in virtual hosting as
that will determine which site is being accessed. The format of the farm label should be the
site host name (i.e. www.xyz.com
), max length 75 bytes. Without a label specified, a 401
(Unauthorized) error code is still considered a live server. If you have a label specified and
the server returns error code 401, then the WebMux will consider that server dead. For both
IIS and Apache servers doing virtual hosting, the farm name label must be an existing web
site name on the server. For more information on Virtual hosting, please go to Appendix D
for details.
Port Number:
You can specify a port number that doesn’t duplicate any existing IP/port combinations. A
port number of “all” will enable all port ranges, but excluding any already existing ports
associated with the specified IP address. Please see the note at the end of this section
regarding the behaviors of the additional IP/port in conjunction with SSL termination.
Service:
This allows you to specify the type of health checking you want the WebMux to perform for
this MAP™ instance.
SSL termination:
You can enable the WebMux to do the SSL termination of this MAP™ instance.
SSL port:
The known secure port for the type of service you selected will be automatically filled in.
You can manually change it if you are using a different port for that service.
Block non-SSL access to farm:
Prohibits non-SSL connection to this MAP™ instance.
Tag SSL-terminated HTTP requests:
This will enable the WebMux to add an “X-WebMux-SSL-termination: true” MIME header
in the decrypted http request sent to the server.
CAUTION If your farm is already SSL terminated and you create an additional IP/port
combination using the main farm IP and specifying the same secure port (or “all”), the
SSL termination by the WebMux will be bypassed and SSL will be done directly by the
server.
