Hi,

I am trying to understand how anonymous web surfing works.
They are know services that proxies a website allowing you to make
requests to a server-in-the-middle and getting the content back,
instead of making it directly to the desired website.

Apparently, they fetch the website content and substitutes
all file/links/image/css references to the external server.

It is pretty much what

<?php include($_GET["http://wikipedia.org"]); ?>

would do, but also fixing all the css, links local references
to the external server.

Using a simple include, this

proxy.php?url=http://wikipedia.org

would fetch html as it is, and may have links like this

<a href="main.html">

while I want it to forward all the local links to :

<a href="http://wikipedia.org/main.html">

Does anyone knows how to do this ?

PS I am trying to avoid html manipulation (like using tidy or
phphtmlparser), but I was wondering if there is any alternative ...
