Apache: single header file for all sub-directories

Hi,

How do I tell the Apache HTTP server (v1.3.37) to use one header file for a directory and all its subdirectories?

I want all directories, beginning with [...]/mirror/openoffice/ to use the file [...]/mirror/openoffice/HEADER.html.

Please keep in mind that I am not the admin of the system and have to use the .htaccess file located in [...]/openoffice/ which currently contains the following:

Code:

---

IndexIgnore .htaccess HEADER.html FOOTER.html
HeaderName HEADER.html
ReadmeName FOOTER.html

---

Thank you.

Anyone know how?
