I am looking for a simple HTTP proxy. I have looked at freshmeat and have
looked at a lot.

Basically, I want to be able to block URLs and content or only allow
certain URLs with a regex. I plan to use it for my son's web surfing.

I am looking at www_proxy from http://www.sashanet.com/.

It seems useful. It can log, spoof the user agent, and run a STDIN/STDOUT
filter, like:
/bin/sed -e 's/<SCRIPT.*SRC.*geocities.*>/<script language=javascript1.3>/g'
-e 's/<SCRIPT.*SRC.*adforce.*>/<script language=javascript1.3>/g'
-e 's/var urlOf/\\/\\//g'

Does anyone have any suggestions for a simple http proxy?

Now my STL question ...

First to use www_proxy, I installed and modified libtcp++ to include
<sys/types.h>.

But when I make www_proxy, I receive messages like:

/usr/include/g++/stl_relops.h: In function `bool operator !=(const T &,
const T
&)':

I found this on the web, but I didn't find any answers. Do I need to
include some header?

I am using egcs-1.1.2 under NetBSD/i386 1.5.3_RC2.
