Removing the server name from the response header of F5

Use this instead of the redirect

HTTP::respond 302 noserver Location "https://[HTTP::host][HTTP::uri]"

But this is the default irule of http  https redirect which I'm using. How to customize it or where to insert the noserver parameter? or should I remove it totally and use the one you provided instead? and will that impact the https redirection behavior then?

Your 302 would be in the HTTP_RESPONSE not the HTTP_REQUEST. You will need something like this... I have not tested this so you might have to make some modifications to it.

when HTTP_RESPONSE {  
  if {[HTTP::is_redirect]} {              
        if {[HTTP::header Server] contains "BigIP" } {
          HTTP::header replace Server "www.servername.com"
        }
   }      
} 

our current situation is as follows, 1- the client requests the server name with http 2- the used irule is redirecting the request to be HTTPS instead of https 3- the back end server replies in https 4- f5 replaces the back-end server_name with "server==BigIP" The issue is, I want to remove "server==BigIP" without affecting the redirection behavior. Is that applicable?

In the latest version (v12.1.2 at this moment), you can get rid of

Server: BigIP

http

http

Server Agent Name

from config:

ltm profile http my_http_profile {
   app-service none
   defaults-from http
   proxy-type reverse
   server-agent-name none
}

Server Agent Name: Specifies the string used as the server name in traffic generated by LTM. The default value is BigIP.
