rproxy

A super simple HTTP/1.1 proxy, with TLS and Let's Encrypt support.

rproxy takes care of your Let's Encrypt certificates, automatically renewing them. This is done by the excellent txacme library.

Install from PyPI:

$ pip install rproxy

Make a directory to store your certificates:

$ mkdir my-certs

Make a rproxy.ini:

[rproxy]
certificates=my-certs
http_ports=80
https_ports=443

[hosts]
mysite.com_port=8080

Then run it:

sudo twistd -u nobody -g nobody -n rproxy

This will start the server, drop permissions (setting the effective uid/guid to nobody), and will proxy incoming requests to mysite.com to localhost:8080. You can configure it further:

[rproxy]
certificates=my-certs
http_ports=80,8080
https_ports=443
clacks=true

[hosts]
mysite.com_port=8080
mysite.com_host=otherserver
mysite.com_onlysecure=True
mysite.com_proxysecure=True

myothersite.net_port=8081

This config will:

• connect to https://otherserver:8080 as the proxied server for mysite.com, and only allow HTTPS connections to the proxy for this site
• connect to http://localhost:8081 as the proxied server for myothersite.net, and allow HTTP or HTTPS connections.

General Config

• http_ports -- comma-separated list of numerical ports to listen on for HTTP connections.
• https_ports -- comma-separated list of numerical ports to listen on for HTTPS connections.
• certificates -- directory where certificates are kept.
• clacks -- Enable X-Clacks-Overhead for requests.

Hosts Config

• <host>_onlysecure -- enforce HTTPS connections. If not set, or set to False, it will allow HTTP and HTTPS connections.
• <host>_proxysecure -- connect to the proxied server by HTTPS. If not set, or set to False, it will connect over HTTP.
• <host>_port -- The port of the proxied server that this proxy should connect to.
• <host>_host -- the hostname/IP of the server to proxy to.
• <host>_sendhsts -- send HSTS headers on HTTPS connections.
• <host>_wwwtoo -- match www too.
