Convert HTTP requests to SOCKS5

Question

I'm currently doing some testing work with TOR and ran in to a small problem. Tor's client only supports receiving connections through a SOCKS5 protocol, but the applications I'm using only support HTTP Proxy Protocals.

Is it possible to put something in the middle? So that for example it went.

My Program (HTTP Only) > HTTP to SOCKS Converter > Tor SOCKS5 Server

It looks like DeleGate can do this, with something like the following (where DeleGate will accept HTTP connections on port 8080 and forward to a SOCKS server on port 9050):

delegated -P8080 SERVER=http SOCKS=localhost:9050

You can also use Privoxy. Add this line to its config.txt file:

forward-socks5 / 127.0.0.1:9050 .

(Don't forget the small dot at the end.)

Then use the HTTP or HTTPS proxy at 127.0.0.1:8118

Tor bundle no longer has polipo, here is from the official tor FAQ:

In the past, Tor bundles included an HTTP proxy like Privoxy or Polipo, solely to work around a bug in Firefox that was finally fixed in Firefox 6. Now you don't need a separate HTTP proxy to use Tor, and in fact leaving it out makes you safer because Torbutton has better control over Firefox's interaction with websites.

If you are trying to use some external application with Tor, step zero should be to reread the set of warnings for ways you can screw up. Step one should be to try to use a Socks proxy rather than an http proxy — Tor runs a Socks proxy on port 9050 on Windows, or see above for OSX and Linux.

If that fails, feel free to install privoxy. However, please realize that this approach is not recommended for novice users. Privoxy has an example configuration of Tor and Privoxy.

You didn't specify an operating system. Please do so in future.

This answer recommends Polipo, which is included in the Vidalia bundle hosted by the Tor project and therefore probably recommended by them for Windows. Polipo also has a *nix version (and was originally designed for *nix), so I've included instructions on how to set it up - see the second section below. It is a rather lightweight solution, if it matters.

##Windows

Download the Vidalia bundle. It includes the Vidalia GUI and a program called Polipo, along with Tor. In the bundle, Polipo by default runs a HTTP proxy on port 8118 that redirects through the Tor SOCKS proxy on port 9050.

###Advanced setup

It's also possible to configure Polipo manually, without the Vidalia bundle.

Taken from https://www.irif.fr/~jch/software/polipo/tor.html

They also provide binaries you should download.

###Configuration

Polipo is configured by setting a number of configuration variables in Polipo's configuration file, which is a plain text file. In order to tell Polipo to use tor and not to cache any fetched pages on disk, you will want to add the following lines to your configuration file:
socksParentProxy = localhost:9050
diskCacheRoot=""
You will also want to disable the local configuration interface in order to protect yourself from browser vulnerabilities:
disableLocalInterface=true

###Running it

When running Polipo, you should specify the location for the configuration file, by using the -c flag on Polipo's command line:
> polipo.exe -c "/Program Files/Polipo/config.txt"
Note that even under Windows you must use Unix syntax for the filename (using forward slashes) and you cannot specify a device (“drive”) to use.

The Polipo default listening port is 8123.

The default config from the Vidalia bundle is included at the bottom of this answer.

##*nix

Includes Linux, Unix, BSD, OS X, most major modern (2012) operating systems that are not based on NT (Windows).

Once again, taken from https://www.irif.fr/~jch/software/polipo/tor.html

Download a package from whatever repository you use. Google may help here. Alternatively, a direct binary can be downloaded.

###Configuration

Polipo is configured by setting a number of configuration variables in Polipo's configuration file, which is either ~/.polipo or /etc/polipo/config, whichever exists. In order to tell Polipo to use tor and not to cache any fetched pages on disk, you will want to add the following lines to your configuration file:
socksParentProxy = localhost:9050
diskCacheRoot=""
You will also want to disable the local configuration interface in order to protect yourself from browser vulnerabilities:
disableLocalInterface=true
If you want to specify a different location for the configuration file, you can specify it by using the -c flag on Polipo's command line.

Note that if you installed Polipo from a distribution-provided binary, it will probably not take ~/.polipo into account — you will need to edit /etc/polipo/config.

###Running it

If you installed Polipo from a distribution-provided package, Polipo is probably already running; you will need to restart it so it takes its new configuration into account. Otherwise, just grab a free terminal window and type:
$ polipo
If you are using a non-standard location for Polipo's configuration file, specify it on the command line, for example:
$ polipo -c "/Program Files/Polipo/config.txt"

The Polipo default listening port is 8123.

The default config from the Vidalia bundle is included at the bottom of this answer.

##Default Polipo config (Vidalia bundle)

This is my default Polipo configuration from the Vidalia bundle for Windows. From the look of it, it should work in *nix too - there's nothing platform specific as far as I can tell. Yes, it is an IPv4 config.

Fiddler also allows a conversion from http request to a socks tunnelled request.

I did this to push some Windows Updates to run through a socks connection (via Amazon EC2 and Putty).

From this page https://groups.google.com/forum/#!topic/httpfiddler/6m2xEe0fRmw

In Fiddler there is a "FiddlerScript" tab where you can add the following:

Using the X-OverrideGateway flag, use the socks= prefix to indicate that >Fiddler should use the SOCKS v4a protocol when speaking to the upstream server.

For instance, the TOR installer sets up an entry point to the TOR network using a SOCKS proxy on port 9150 called Polipo. You can add the following inside your FiddlerScript’s OnBeforeRequest method to route any request to test.example.com through the TOR network:
    if (oSession.HostnameIs("test.example.com")) {
      oSession["x-OverrideGateway"] = "socks=127.0.0.1:9150";    
  }
If you’d instead prefer to send all of the traffic via the SOCKS, you can simply set the X-OverrideGateway flag unconditionally for each Session.

A really nice solution can be found in tinyproxy. According to its homepage it is a "a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems". The project is over 22 years old and still actively maintained. It can be configured to forward all traffic to an upstream socks proxy using the following line in its config file:

upstream socks5 $IP:$PORT

Alternatively it can be configured to split traffic to one of several upstream proxies, depending on the target URL:

upstream socks5 $IP1:$PORT1 ".some.domain"
upstream http $IP2:$PORT2 ".some.other.domain"

Any traffic that is not explicitly routed through an upstream, will be routed via the gateway of node that is running tinyproxy.

WinGate can also do this. Check the Connection tab on your WWW proxy and you can choose upstream SOCKS4, SOCKS4a, or HTTP proxy.

WinGate also has a free license for 10 concurrent users.
