calling javascript from a secure server

[Andy]

Hi,

I have a question - I want to install some affiliate tracking code on my
site. I need to put some code on the secure server where the transaction is
made.

I can either do this using a hidden image or by calling javascript function
on my server. Since my server hasn't got https, I know that the browser
gives warning about displaying insecure items if you use the hidden image
method. Does anyone know whether you can access a javascript file from a
secure server to a non-secure one and whether the browser displays a
warning?

Thanks,

Andy.
