[Filterproxy-users] Proxy relaying

[James S. W. <ja...@ja...>]

I was wondering if anyone had encountered my situation before.
I am tyring to get Apache's mod_proxy to proxy through filterproxy using

ProxyRemote http http://127.0.0.1:8888

But when I do It just hangs. I want to proxy a site without having to set up
a proxy server in my browser setup. I guess my question is, Is there any reason
why this shouldnt work? My thanks in advance.

[Filterproxy-users] FilterProxy 0.29.2

[Bob M. <mce...@dr...>]

=2E..has been released.

This is an interim release containing many bug fixes.  I'm about to rip
out Parse::ePerl, and wanted to make sure these bug fixes got out first.
(check the ChangeLog)  I have tried installing Parse::ePerl on a perl
5.6 machine recently.  It was ugly.  Very ugly.  I even tried to make
eperl rpms.  That was uglier still.  If you're using FilterProxy with
perl 5.6, consider yourself supremely talented.

Also in this release is a new Source module thanks to John Waymouth.
It works two ways:=20
    http://source/url=20
or=20
    http://localhost:8888/Source.pm?url
where url is the url you want to load.  Note this will show you the
UNFILTERED source by converting the mime-type to text/plain.  There are
a few neato javascript bookmarks on the home page:
    http://draal.physics.wisc.edu/FilterProxy/
to do things like: "view unfiltered source for this page", "enable
filtering", "disable filtering", and bring up the config page.

Numerous rule updates, including some to block evil javascript
popups/popunders.  If you have written new rules for FilterProxy, please
send them to me and I will include them in future distributions.  I was
pleased to discover that the new jump-through ads on salon.com were
already filtered by existing rules!  We shall see whether some new
announced "filter-detector" will actually work on FilterProxy:
    http://slashdot.org/article.pl?sid=3D01/09/29/002222
I will postpone my musings about the future of internet advertising for
another day, but if you search the above discussion you will find a
comment by me on the subject.

Also, FilterProxy now loops over the modules in the FilterProxy/
directory and tries to load them all.  If they fail to load it will
print an error message, but FilterProxy WILL STILL RUN if some modules
do not load.  You will probably discover that there is an ImageComp
module, which will recompress jpegs, among other things.  But it depends
on ImageMagick (something I haven't installed)...and will fail to load.
This is not a problem.  You can still use FilterProxy as usual.

Coming soon:=20
    "View how this page was filtered" -- marked-up source.
    HTML::Mason replacing Parse::ePerl.

Off I go to install perl 5.6...

[Filterproxy-users] Re: filterproxy

[Bob M. <mce...@dr...>]

It looks like you're using mandrake packages on a redhat system.  And
the packages you got want perl 5.6.1.  FilterProxy itself is happy with
perl 5.005 or later.

Ah, and it looks like you got some pld rpms too.  PLD (Polish Linux
Distribution) puts things in hosed places (like "i386-pld-linux" below)
that redhat won't be happy with.

Finding redhat packages is much harder now than it was a year ago.  You
used to be able to just use rpmfind and it would grab things for you.
Now PLD and Mandrake packages are largely incompatible with redhat.
Redhat also used to have all the CPAN packages in rpm format, but they
haven't updated it in years and now they're horribly out of date.  :(

The *easiest* way to do this is to build it yourself.  Grab the source
for eperl from the Debian project:
    http://packages.debian.org/unstable/devel/eperl.html
At the bottom there's the links to Source Code:
    http://ftp.debian.org/debian/pool/main/e/eperl/eperl_2.2.14.orig.tar.gz
    http://ftp.debian.org/debian/pool/main/e/eperl/eperl_2.2.14-3.diff.gz
Apply the patch, build, and install the thing yourself.

Second, use the perl CPAN tool to install the rest:
    > perl -MCPAN -e shell
[...]
    CPAN> install Compress::Zlib
    CPAN> install Bundle::LWP
    CPAN> install Time::HiRes
That should do it.

If anyone wants to send me rpms for any of these, I'd be happy to put
them on my site for people to download.

Hmmm...I suspect a browser bug.  I have tested it with the following
(linux) browsers:
Mozilla (0.8 onward)
Netscape 4.x
Netscape 3.x
StarOffice
Galeon
Skipstone
Konqueror

=2E..and none of them had a problem with compressed data, so I suspect a
browser bug.  (Netscape has a few bugs with compressed data too...but
doesn't crash, just displays binary junk -- in <iframe>'s)

Try this URL:
    http://groups.yahoo.com/group/http-wg/messages/8730?expand=3D1
WITHOUT the proxy and see if it crashes your browser.  This particular
yahoo server also spits out compressed content.  See if it crashes your
browser.

Also, turn on debug, and also turn on "Dump headers to log file" in the
Header main config page.  Check if your browser is sending the
Accept-Encoding header.  If all else fails, mail the FilterProxy.log
file to me (with debug and headers dumped to log file turned on!) and
I'll take a look at it.

What's the latest version of MSIE?  Might be worthwhile to upgrade...

Yes.  Instructions are in the README (starting on line 70).

[Filterproxy-users] FilterProxy 0.29.1 Released

[Bob M. <rsm...@st...>]

FilterProxy 0.29.1 has just been released, with the following changes:
  * Fixed Rewrite bug when using 'attrib' and 'rewrite'.
  * Fixed Rewrite bug when using 'attrib', and attrib has no value.
  * Fixed Rewrite bug when using 'inside' predicate.
  * Minor error message clarification.

As I promised earlier, I'll release 0.30 when Parse::ePerl has been
replaced (not sure when I'll get to that), but I thought I should get
these bug fixes out too.

P.S. Is anyone on these lists besides me?

Cheers,
-- Bob
