    Hi MattNears,

    If server's response contains "Server" header or "X-Powered-By" header or other headers in the iRule, "Server" and "X-Powered-By" headers will come back with the actual server and IIS details. You should use "else" blocks and HTTP::header replace command.

    if { !([HTTP::header exists "Server"]) } {
	HTTP::header insert "Server" "A-Server"
} else {
	HTTP::header replace "Server" "A-Server"
}

Just to resurect this thread a little and ask a new question, I managed to resolve me Secure cookie issue, found it in the cookie persistence profice and have that now working nicely.

 

My new issue seems to be on if { !([ HTTP::header exists "X-AspNet-Version" ])} {HTTP::header remove "X-AspNet-Version" } not working and removing the header as it should. Now I did consider switching it and adding an arguement to insert a ficticious value anf then use else and remove but this hasn't worked either. I'm sure I'm missing something but just struggling to work out what I've missed.

Any advice will be wlecome here.
