HTTP Server Header

HTTP response from an LTM have a server header "BigIP"

 

 

Without an iRule on each of my virtual servers, or http profiles fiddling with headers on each of my virtual servers ... is there a way to change this header (globally) ?

 

 

I obfuscate the server header on my web farm, but the BigIP gives the game away when I use iRules to generate responses (ie redirects, sorry pages etc.)

 

 

Thanks

    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).
