I was curious, when I have a list of proxies for example:

1.1.1.1:80
1.1.1.2:80
1.1.1.3:80
1.1.1.4:80
1.1.1.5:80

and I want to reach the target, without the target logging my IP, its possible to use one proxy. But you are never sure if this proxy keep track of things you do. Is it possible to use more then one proxy?

http://1.1.1.1:80/http://1.1.1.2:80/http://1.1.1.3:80/http://1.1.1.4:80/http://site.com

That should work as long as the proxies are in good working order. It's not a guarantee though.

Isn't it possible to configure Firefox for example with multiple proxies?

I remember once reading up on how in IE in the proxy text box you can enter this to chain them:
1.1.1.1:80-_-1.1.1.2:80-_-1.1.1.3:80-_-1.1.1.4:80

2 things i've forgotten is wha to put in the port box, i'm guessing leave the last proxy with no port and have the port in the port box, like this:
1.1.1.1:80-_-1.1.1.2:80-_-1.1.1.3:80-_-1.1.1.4 80

and second is if its -_- or _-_... try both... at first i thought it was some joke, but i tried it and it worked.

not all programs support this way, alternatively you could use programs like:

win: sockschain
lin: proxychains

/me highly recommends proxychains for *nix based pc's

And im pretty sure you can use tor to chain proxies in windows. Ive only heard good things about tor.

Thanks dudes, I think this is all info I need

Will post my findings different methods.

This might help you.

MultiProxy will do the work if you is on a Windows system. As for *unix I recommend proxychains as bonarez also suggested.

http://freeproxy.ru/ and check downloads section, they provide nice proxy chain software.

I'd like to work with Proxifier. Because u can let every client (like I.E., nc, mIRC, ftpclient etc etc) run trought your proxies.

There's no need to download any other software.
Normally, browsers add http:// when you type www.anything.com. So I think they are able to add a proxy chain string,too. All you have to do in IE is to modify the registry. I don't know about Firefox how it works there.

Maybe someone should put a registry string that does it
