Here are two ways you could do this. (I'm sure other people have other methods.) Use a routine to create your links for you or post process the TT content.

Method 1.) Stop hard coding links and create some kind of routine that builds your links for you. We utilize a method like so: [% api.url('index.html') %]. This automatically prepends the server portion as well as appends session ids if necessary. It also automatically does uri encoding and html encoding. (Toggle-able via options passed.) You pass your routine in with the vars parameter to ->process. An example vars:
{
  api => {
           url => sub{
             my ($page, $cgi_hash_or_string, $opt) = @_;
             #build link here.
           }
         }
}
You don't have to use the api key there, however, I like to keep clutter of TT top level variables down.

Links now look like: 
<a href="[% api.url('index.html') %]">index page</a>


Method 2.) Post process your content. Use an HTML parser and modify all links as necessary.

I like the first method, because it gives you a lot of control over the links on your site.
