Yes, you can. You'd have something like this:
<cffunction name="onRequest">
<cfargument name="targetPage">
<cfsavecontent var="page">
<cfinclude template="#Arguments.targetPage#">
</cfsavecontent>
<!--- your regex stuff goes here --->
<cfoutput>#page#</cfoutput>
</cffunction>
Alternatively, you could append data to links with JavaScript. This is very
easy to do, since all the links are in the document.links array. This would
perform better, but would obviously only work for clients that have
JavaScript enabled.

I don't recommend you do this, actually. While it may have been a problem in
2002 when that article was written, it really isn't a common problem today.
For that matter, I don't think it was all that common a problem in 2002. But
anyway, nowadays, proxy servers tend to be well-behaved; if you don't want a
file to be cached, there are all sorts of META tags you can embed in the
page to instruct proxies.
