The “Modify Farm” screen looks like this. Some of the fields will be hidden or displayed depending
on some of your selections.
Farm IP Address and Port Number
The farm IP and port that is being modified will be displayed. These fields are set in the
“Add Farm” screen. Once set, they are not changeable. If they must be changed, delete
the farm and then add a new one.
Label
This is for your visual reference to be displayed on the main console for the farm entry. It
can be any alphanumeric text.
Virtual Host Name
For web servers that are serving name based virtual hosts, this field will be important for the
WebMux to perform a correct health check. The WebMux uses the data in this field as the
host name for the HOST mime header in its HTTP health check requests to the servers. In
some cases, name based virtual hosts have a default site that will still respond with a 400
OK even if a HOST MIME header is not specified in the request. In that case, leaving this
field blank may not have a negative effect. However, in other cases, a request that does not
have a specified HOST MIME header will end up receiving response from the server such
as 503 Service Unavailable. In which case, the WebMux will mark the server dead.
Therefore, it is important that you specifiy the correct host name of the site you are serving
for the farm in order for the WebMux health check to reach the correct site and get a valid
response from the server.
