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.

SSL Termination:
You can change the SSL key/certificate pair used for this farm. All current connections for
this farm will be reset if you change the key/certificate pair selection.
Block non-SSL Access to farm:
If you do not want to allow non-encrypted traffic connecting to the farm, select “Yes.”
Tag SSL-terminated HTTP requests:
If SSL termination is active for this farm, choosing “Yes” for this option will add an “X-
WebMux-SSL-termination: true” MIME header in the decrypted http request going to the real
server.
Connection throttling watermarks:
Setting a value in the “high” field will control the maximum number of concurrent
connections allowed on a farm. The “low” field will control when to resume allowing more
connections. For example, with a high set to 20 and a low set to 10, the WebMux stop
allowing more connections when the number of concurrent connections hit 20 and new
connections will not be allowed until the number of concurrent connections drop to 10 or
below.
