Force Apache to send the correct encoding

["Marcelo de Moraes Serpa" <celoserpa@xxxxxxxxx>]

Hello,

This might be a simple question, but I'm having issues serving HTML files with the ISO-8859-1 encoding. I could, in theory, change the encoding of each file, but doing so for thousands of files is not so practical.

I've got a VirtualHost and inside it I have an alias:

    Alias /doc "/home/dtweb/static/documentation/"
        <Directory "/home/dtweb/static/documentation/">
           AllowOverride All

           Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
           Order allow,deny
           Allow from all
        </Directory>


The documentation dir has all these html files. Apache seems to be serving them with a UTF-8 encoding. 

How could I force apache to tell the browser to use ISO-8859-1?

Thanks in advance,

Marcelo.
