I used this to give some additional information about our local Debian mirror.
create your .htaccess with the following contents:
ReadmeName README HeaderName HEADER <Files ~ "(README|HEADER)$"> ForceType text/html </Files> Options +Indexes IndexIgnore images *.ico
put something like this into your HEADER:
<HTML> <HEAD> <TITLE>Our local Debian mirror</TITLE> </HEAD> <BODY> <H1>Debian Mirror</H1><HR> <P>Welcome to our local Debian mirror! </P> <P>To use this mirror add the following to your <TT>/etc/apt/sources.list</TT> <br> <TT><B>deb http://debmirror.foo.lan/debian/ sarge main non-free contrib</B></TT> </P> </BODY> </HTML>
if you want to put some text into the page footer create a file README and enter some HTML code:
<address>something to know</address>
