You can start it (after downloading and decompressing it to c:\Rabbit) with the command
java.exe -classpath . rabbit.proxy.Proxy
Before running it, especially on Windows platforms, you must configure it. It isn't very complicated. conf\rabbit.conf contains the generic configuration. Under Windows, use some kind of non-notepad text editor - for example, Wordpad - at first because it only contains LF characters.
If used under Windows, you most probably want to switch off rabbit.proxy.DNSJavaHandler and enable rabbit.proxy.DNSSunHandler instead if the proxy run on your particular destop device can't resolve host names, but plain IP's work. That is, comment out the first and remove the hash before the second property as in:
#dnsHandler=rabbit.proxy.DNSJavaHandler
dnsHandler=rabbit.proxy.DNSSunHandler
For enabling proxy chaining, fill in the two properties proxyhost and proxyport (see the This is the proxy that RabbIT should use when getting its files. Leave it blank to dont have a proxy. Both of these need to be set, or they will be ignored. section). The default port number the proxy uses is 9666.
If you want image downscaling, look for the convert property and make it point to the convert program in ImageMagick. In Windows, it'll be something like this (the actual ImageMagick version may be different on your PC!):
convert=\Program Files\ImageMagick-6.2.1-Q8\convert.exe
Please note that you can't use " marks in here. Furthermore, you will only get a warning of RabbIT's inability to find ImageMagick in logs/error_log in the form of
[13/Jun/2005:10:16:48 GMT][WARN][convert -"C:\Program Files\ImageMagick-6.2.1-Q8\convert.exe"- not found, is your path correct?]
To enable advertisement blocking, you may want to modify the httpinfilters property as follows:
httpinfilters=rabbit.filter.BlockFilter,rabbit.filter.HTTPBaseFilter
You may also want to edit the contents of the blockURLmatching property to add/remove blocked URL's.
If you also want to use the proxy with a desktop-based Internet Explorer, enable the HTTP/1.1 extensions for proxies in Internet Options/Advanced tab.
