[Filterproxy-devel] New module for FilterProxy

[John F W. <way...@wp...>]

Ok, so, I read the slashdot article about popups, and decided I was once
and for all pissed off enough about ads to do something, so I searched
around for a decent html rewriting proxy for linux.  Yours seems to be the
best one I've found, and, BONUS!, it's for PERL!

So, I checked it out, and must say I'm impressed by its out-of-the-box
ability to block a ton of stuff.  But I'm a website designer, and I can
see a need to access the original source of a document, including content
that would otherwise have been rewritten/removed.

I hacked together Source.pm as a rudiimentary way to view the original
source of a file.  The basic gist of it is that urls targetted at the fake
host "source" get snagged and their content-type is set to text/plain
(yes, I'm a cheapass).

To get it working, bring in the module in FilterProxy.pl, and add a filter
rule for all urls looking like this:

http://source/?http://foobar.com/document

I allowed any amount of /'s after the source, including none, just in
case.  It occurs to me that maybe I should use http://source/URL to fully
fall within the guidelines for a correct URI (avoid having two ?'s for GET
documents).   Ah well, another version.  Anyway, I point the filter rule
at Source, and also turn off every other filter (maybe I should leave
Headers).

To make usage easier, I created a bookmark (in the Mozilla Personal
Toolbar) of javascript:window.open("http://source/?" +
document.location);, to allow easy source viewing.

For now, well, it works, sorta.  I seem to get some HTTP cruft at the top
and bottom, (like a 0 at the end?) and, in mozilla, the connection doesn't
seem to want to close... ideas?

This is a major hack.  I'm mostly sending it to you to get the idea out in
the open.  I left the version as 0.01 on purpose ;) I'm thinking in the
future that I could actually return an HTML document, escaping all of the
HTML, and prettifying it with syntax hilighting using <font> tags for
color.  That might also avoid the problems above.  However, I'm not sure
I'll be able to do much more work on this in the near future, because I'm
dealing with RSI problems.  I'm pleased to have gotten this to work thus
far :)

Anyway, I hope you like my meager contribution to your project, and if you
feel it's actually worth distributing, feel free to modify it and/or add
it to your project, it's GPL'd.  And thanks for a very useful program :)
