-- get http headers
headers = avi.http.get_header()

for header,value in pairs(headers) do
  if string.beginswith(string.lower(header),"x-") or string.contains(string.lower(header),"server")  then
      avi.http.remove_header(header)
      -- generate log message
      avi.vs.log("Header Removed: " .. header .. " : " .. value)
  end
