How to stop drupal from creating another consolidated CSS file for each node type?

Question

I have a rather large Drupal 6 site with various modules included for different types of node / page, which leads to the creation of a different CSS file for each type of page after combining CSS. I understand the logic of not wanting to load css for each module, but is there a way to load sitewide css into a single file so that we can take advantage of CSS caching?

Homepage:

<link type="text/css" rel="stylesheet" media="all" href="/site-files/example.com/files/css/css_1f2e88da1acf78556ee565984845d7cd.css" /></code> 

Article:

 <link type="text/css" rel="stylesheet" media="all" href="/site-files/example.com/files/css/css_1786ec41724511f6c0984222b790dca6.css" /> 

Category:

 <link type="text/css" rel="stylesheet" media="all" href="/site-files/example.com/files/css/css_b7f516c6ab4921929598cfd377ce4523.css" />

There must be some logic when creating these files if you think the difference between them is minimal.

Answering my own question ...

As always with Drupal, someone was already there and did it, and here it is:

A small additional study of the advantages of first page load time compared to a cached file on the site side, etc. It was very insightful.
