I'm trying to change the brokerwide HTTP Listener/connector parameter

The default value is Apache-Coyote/1.1 and as per documentation this value can be changed.

Quote:

-n serverName
Set the value that is set in the "Server" header for all HTTP responses sent by this server.
Value type - string
Initial value - Apache-Coyote/1.1

Can this value be completely removed for all the HTTP response of broker.

I was able to change the name from Apache-Coyote/1.1 to a random string.

Is it possible to completely remove this parameter?

if complete removal is not possible, can we make this parameter NULL?

So far I tried

Quote:

mqsichangeproperties BROKER -o HTTPConnector -n serverName -v NULL

mqsichangeproperties BROKER -o HTTPSConnector -n serverName -v NULL

if I pass NULL it is not updating the broker.(just tried NULL, not sure if NULL is allowed or not.)

I have even changed did some changes in the broker file
(i know it is not recommended but wanted to check )

Quote:

IBM\MQSI\registry\BROKER\CurrentVersion\HTTPListener\HTTPConnector\serverName.dat

if I delete the contents of this file or delete the whole files, the broker is defaulting the server name back to Apache-Coyote/1.1

Is there a way to make it NULL or completely disable or make it empty?

Hi Abhi ,

Quote:

worked
-n serverName -v "{space}"

Aparently single quotes with space did not work

If I pass space as value then in the Http response header the serverrname is empty, if I just give "" two quotes with no space or two single quotes with no space in those cases the value is defaulted to Apache-coyote/1.1.

Now as I can send empty server name in response that is okay but is there a possibility to completely disable that parameter?

If I make it Empty or deleted the serverName.dat file from registry folder then it is automatically taking Apache-Coyote/1.1 by default
