+ complexity of what goes into making up this one <SPAN

+>"page"</SPAN
+>. There
+ are eight different domains involved here, with thirty two separate URLs
+ requested in all, making up all manner of images, Shockwave Flash,
+ JavaScript, CSS stylesheets, scripts, and other related content. Some of this
+ content is obviously <SPAN
+CLASS="QUOTE"
+>"good"</SPAN
+> or <SPAN
+CLASS="QUOTE"
+>"bad"</SPAN
+>, but not all.
+ Many of the more questionable looking requests, are going to outside domains
+ that seem to be identifying themselves with suspicious looking names, making
+ our job a little easier. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> has <SPAN
+CLASS="QUOTE"
+>"crunched"</SPAN
