Firefox/Opera Browser do show Source instead Content??

Hi,
i am not sure if that is a LUA/Corona or any other problem.
Still I hope someone has a solution;

I created a simple HTML Server with LUA (corona environment)

Anyhow while connecting from Safari/Chrome the Page is displayed fine, but with Opera/Firefox, I get instead the Source Code shown instead??

Do i have to send kind a PreHeader or what can be the reason.

For example

[html]  
  
 hello **test** how are you  
  
[/html]  

Safari/Chrome does show as expected just: " hello test how are you "

But Opera/Firefox does show the source itself as example above!!?

ok… solved it…
had to send
client:send(“HTTP/1.0 200 OK\r\nContent-type: text/html\r\n\r\n”)
before anything else
