Yes and yes. Other sites get completly recompressed.

Except for the expire parse error? No.

I don't think so.
I have convertargs=-quality 10 -flatten $filename +profile "*" jpeg:$filename.c
and if i use that with convert on this picture it is 6674 Bytes large.

That is normal. Small images should not get compressed, since the 
download time
gain will be lost in latency (caused by rabbit converting the image).
Also rabbit inspects the http headers and checks the mime type. If the 
server
is badly configured or the cgi/jsp/servlet/asp/whatever is evil it will 
send a
mime type that rabbit does not understand.

Hmmm, looks odd. Not sure exactly why that fails, I will have to test it.
That is only a warning, it should not affect other image conversion.
It might affect cache length though...

No.

Do you have imagemagick installed and can rabbit find convert?

Ok, doing a HEAD on the above image I get a response:

Hmmm, not sure why rabbit does not convert that...
Do you get anything in the error log?
Does the image get larger after conversion?
in that case rabbit will send the original...

[Rabbit-proxy-users] no image compression

[Holger K. <hol...@gm...>]

Hello,
i found that while using rabbit on some sites the images don't get recompressed.

For every such image an entry in the error_log shows up.
[14/Dez/2004:22:03:06 GMT][MSG][unable to parse expire date: 'Thu, 14 Dec 2006 22:03:06 GMT' for URI: 'http://images.gmx.net/images/bs/21000/skyscraper_wechsler_v2.gif']

That seems strange because the expire date looks perfectly normal to me.
Is the compression problem related to the expire parsing problem?
I'm using 
java version "1.4.2_05"

Hi,

If have some troubles with the current version (2.0.35) of RabbIT, slow

How are you running rabbit?
You know that its supposed to look like this:

Client (IE) <---- slow link ----> rabbit <--- fast link ---> Internet

That is, normally it is your ISP that runs rabbit for you.
Or you set it up at home for usage when you use dialup from
your notebook.

If you run rabbit on the same machine that you use for web browsing
you will normally see a slowdown in surfing speed.

If you do it correctly and still have problems, then please get
me some network traces (ethereal is a nice network snooper).

Most probably rabbit thinks it has another name, rabbit
takes one of the names of the machines, it does not use all.

Try a few of the names, like for me:
http://ghoul:9666/  => does not work
http://ghoul.khelekore.org:9666/ => works...
http://192.168.0.43:9666/ => does not work
http://localhost:9666/ => does not work...

Also check that you have rabbit as the proxy _even_ for the
host running rabbit since rabbit is better on handling
proxy requests than web site requests...

Hmm. odd. What filters do you have enabled?

If you have the FilterHandler on, can you see if you still get a problem

Sometimes, when visiting webpages through Rabbit, the page that I

Yes,  you need java/1.4 to run the latest rabbit (Actually it has

I have recieved this information before. So yes, other are also having
trouble with thoose services.

The easy way for you is to not route thoose requests through rabbit.
(You requires a high level router for that).

If the users are using IE and the resources are using NTLM you can
not use rabbit. IE will not try to establish NTLM connections over
any proxy (what I can see). Note however that if you use mozilla or any
other browser, that tries to use NTLM even though there is a proxy in the
way, it will work.

Windows update is IE only what I know. I am not sure about norton,
I do not use it (I am on linux/unix system almost all of the time).

If it is not NTLM, then I would like to get network traces so I can see
what happens. Relevant log entries are also interesting.

[Rabbit-proxy-users] rabbit 2.0.34-pre1

[Robert O. <ro...@kh...>]

Hello!

I have released the 2.0.34-pre1 version.
This version includes a fix to the html-parser. It would
be good to hear about non-working sites. So if you have
the FilterHandler on please test it.
The problem only occurred when a html page with
javascript/style in it got split over several network packets
and the javascript/style was split into several packets.
(Very fun to try out, downloading the site and trying to
parse the page from disk resultet in correct parsing :-).

There is a fix for windows users as well.
And the default convert-arguments now include the
' +profile "*" ' that ought to remove exif-headers and
other similar stuff. May shrink some images even more.
(best reported result 19k->5k).

Re: [Rabbit-proxy-users] Which Java version?

Thanks Robert, that fixed the problem. I had both Java 1.3 and 1.4, but 
neither were in the path. Adding the path to Java 1.4 got the proxy up

SonyEricsson P800 phone via RabbIT running on my home PC.

I read this as you having both java1.3 and java 1.4 installed.
And that you have 1.3 in the path, but not 1.4.

[Rabbit-proxy-users] Which Java version?

[Anthony H. <an...@gr...>]

I installed RabbIT proxy by just unzipping the RabbIT2.zip download from 
sourceforge, and then did "java rabbit.proxy.Proxy" from a command 
prompt to try and run it. I received the following error:

"Registry key 'Software\JavaSoft\Java Runtime 
Environment\CurrentVersion' has value '1.4', but '1.3' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment."

One of the threads in the projects's archives mentions:

"For 2.0.30 you need java/1.4 and you will see this if you try to use
  an earlier java vm."

I'm using 2.0.33 (latest as of 17/07/04) so would expect it to use Java 1.4.

I dont want to install Java 1.3 in case this breaks 1.4. Can anyone help?

I'm running Windows XP Pro SP1.

Thanks, Ant

Hmm. I get a login dialog both when I access it through rabbit and when
I do not use a proxy. I also can not see any thing in the cache after I
get the login dialog.

What browser do you use?

Since I do not have a user account there I can not log in and see if the
server outputs a cacheable response.

Is the page in rabbits cache?
(run the stand alone CacheStatus program to find out).

I had run into the same problem when trying to access the web based
management for the proxy server. It would just spit back the 403 forbidden
error and never prompt for a username/password. The fix was to make sure
that the DNS entries for the proxy server matched the hostname for the
proxy, and the browser was set to actually use the proxy. Once that was
done, the system would prompt as expected. I have not tried the username
based access for using the server in general, but those steps may fix what
you are seeing.

I think you are mis-understanding the problem.

There is an authentication mechanism that is supposed to verify your

With rabbit I get an error because authentication is never attempted.

If you are trying to access the management screens, you need to make
sure that the DNS entries match the hostname for the computer, and that
the browser you are using is set to use the proxy.
