Hide a string in a file before git commit

Question

I would like a specific string in a specific file to be hidden every time I commit changes to that file.

Actually, I have a URL in a file that shouldn't be public in a remote repository. Is there anyway to hide it using pre-commit and post-commit hooks or something similar?

Currently I am working with a git repository but it would be nice to know how to do this with svn.

Thanks, Simão

You could keep that string in a separate file (such as a resource file, if your environment supports that), and not put that file under version control.
