I need to control the headers sent by apache

Hello.

I need to control the headers sent by apache.

    Pragma: public
    Last-Modified: ### The last-modified date should go here ###
    Cache-Control: no-store, no-cache, must-revalidate
    Cache-Control: pre-check=0, post-check=0, max-age=0
    Content-Transfer-Encoding: none
    Content-Type: application/octetstream; name="###   The name of the file should go here   ###"
    Content-Disposition: inline; filename="###   The name of the file should go here    ###"
    Content-length: $content_len

So, if someone click on "page.html" the above headers will be used.

How can I get the above headers to be used for all files in a given directory?

Thanks!
