Hello Gilev,

Your code contains error, try the following :

Also from ssh check the log file in real time using command

tail -f /var/log/ltm

 

when HTTP_REQUEST { 

    if { [HTTP::header exists "Header"] } { 

        set insert_response_header 1 
        set header_var [HTTP::header value "Header"]
        log local0. "Header value in request $header_var"
        pool pool_POOL_HLS 

    } else {
        pool pool_POOL_HLS 
    }

} 

when HTTP_RESPONSE {

    if { $insert_response_header eq "1" } {            
        HTTP::header replace "CORS" $header_var
        log local0. "Header CORS value [HTTP::header value "CORS"]"
    } 
}

 

Hope it helps
