Hi Jason,

 

 

In 9.4.2+ you can suppress the server header in iRule-generated responses using the 'noserver' flag for HTTP::respond:

 

 

http://devcentral.f5.com/wiki/default.aspx/iRules/http__respond

 

 

HTTP::respond [content ] [noserver] [ ]+

 

 

The noserver flag was added in 9.4.2. It suppresses the insertion of the 'Server: BigIP' header. The noserver flag must be included after the content (if any).
