This is correct behavior. What do you need help with?

but it's written to the production log file
Yes. Again, this is correct behavior.
the client says he can see the request?
In the log file, as expected? Or in some other way?
and he doesn't want to see the request
Sounds like you need to change the logger configuration. Look at the config/environment.rb and config/environments/production.rb files to set things up the way you want them.

please explain me in brief
It is clear that English is not your native language, for which I will make allowances. Even so, you aren't really asking questions or giving enough information to get the help you seem to need. I can make guesses about what you're trying to do, but they are just guesses.
Worse, the impression I'm getting is that you are selling services based on your Rails expertise without having actually learned the basics of how to develop with it. I hope I'm wrong about that and it's just a language problem, but if I'm right then you are doing a disservice to every competent Rails contractor out there by attempting to sell something you can't deliver.
