Assuming you are on an Apache server, have a look at the posts in the WebmasterWorld Apache Web Server forum on how to deal with unwanted query strings using mod_rewrite (if on Windows try that forum).

There is nothing you can do about this with a robots.txt file.

The 304 response means that the content has not changed since last requested.

i need to prevent Google to spider that query

file.html is not the same like file.html?ref=example.com

i do not have mod_rewrite :( - please how is the syntax to prevent Googlebot from spidering that fake query?

i need disallow: ref=

or what ? i do not use querys with ?ref= - so it must be easy to disallow Googlebot to spider that file with this query?

[Reilly]

i have found this

Disallow: /*ref=*

does this disallow Google to spider that ?
