Most web sites embed links to other web sites. This link describes what
happens when you load a page.
http://www.surferprotectionprogram.com/Proxy/DOCS/user_manual/user_manual.ht
m#qstart_whathappens
(Note that you may have to concatenate the url listed above. It starts with
"http" and ends with "whathappens".)
The reason your pages are now taking so long is that you have stopped
portions of the pages from loading. These portions must timeout before the
page finishes loading. For the dilbert example, you need to allow the sites
that begin with:
http://adsremote.scripps.com/html.ng/
and
http://adsremote.scripps.com/js.ng/
If you a allow these urls, they will load then tell the browser to go get a
page from
http://adfarm.mediaplex.com/ad/
This page you want to block.
It helps to have a tool that can show you all of the pages that load when
you load www.dilbert.com. The http proxy from the manual above lets you use
regular expressions to block sites and to permit sites. It turns out, there
are just a handful of patterns required to efficiently block advertisers and
fewer patterns that must be allowed. There is no standard, it just happens
that everyone uses similar naming conventions. In dilbert, the /html.ng/
pattern is permitted, but the /ad/ pattern is blocked. When using the http
proxy, even though you permit hte /html.ng/, the proxy strips several tags
out of the outinging http request - so your privacy is maintained.
Two nice things about using an http proxy:
1. all of your http tools can be directed to us it, not just your
browser.
2. once you start blocking advertisers, most of the pop-ups stop
appearing.
