I need to redirect all files in a **particular directory of a particular site** to the same directory of other site. For example:

`http://www.mysite.com/dir/file1.html ---> http://www.mysite2.com/dir/file1.html`

`http://www.mysite.com/dir/file2.html ---> http://www.mysite2.com/dir/file2.html` 

`http://www.mysite.com/dir/file3.html ---> http://www.mysite2.com/dir/file3.html`

Thank you.
