[Zope] Acquisition isn't always bandwidth and browser-cache friendly,advice needed

[Jim Washington]

I don't know if this is the _best_ solution, but it should solve the
problem you are addressing:

Since you already have a lot of files asking for <dtml-var
"images.logo">, you could create a dtml method in your root folder
called "images.logo" that looks like the following:

<img src="<dtml-var BASE0>/images/logo">

As a bonus, you could make it link the image to your top page:

<a href="<dtml-var BASE0>/index_html"><img src="<dtml-var
BASE0>/images/logo" border="0"></a>

This way, you can still acquire images.logo, but have it call the same
URL for the image every time.
