A web proxy for evading corporate or government filters, similar to CGIproxy / PHProxy / Glype but written in node.js. All data is processed and relayed to the client on the fly without unnecessary buffering.
Any website that the proxy can access can now be reached by the proxy's users.
The script uses "pretty" urls which, besides looking pretty, allow links with relative paths
to just work without modification. (E.g. <a href="path/to/file2.html"></a>)
In addition to this, links that are relative to the root (E.g. <a href="/path/to/file2.html"></a>)
can be handled without modification by checking the referrer and 302 redirecting them to the proper
location in the referring site.
Cookies are currently storred in the visitor's session on the server rather than being sent to the visitor's browser to avoid having a large number of (possibly conflicting) browser cookies once they have browsed several sites through the proxy.
Requires node.js >= 0.6 and Redis for session storage.
Then download node-unblocker, cd into the directory, and run npm install -d. Optionally edit
config.js then run node server.js to start the server. It should spawn a new instance for each CPU
core you have.
This project should be runnable on a free Heroku instance without
modification - see http://node-unblocker.herokuapp.com/proxy for an example. You will need to run
heroku addons:add redistogo and it would also be wise to run heroku config:add SECRET=[something only you know] to make the session cookies secure. You may also want to run
heroku addons:add piggyback_ssl to enable secure browsing and/or
heroku config:add GA_ID=[your Google Analytics ID, ex: UA-12345-78] to enable usage tracking via Google
Analytics.
- Mini-url form

- Added support for more charsets via Iconv. (Issues #10 & #11) ** This may have broken compatibility with Windows, more investigation to come. https://github.com/nfriedly/node-unblocker/zipball/v0.7.1 is pure JS and known to be Windows-compatible.
- Added GA tracking and and noindex/nofollow meta tags to proxied pages
- Improved status page to show cluster-wide statistics (Issue #4)
- Fixed issue #7 to better track concurrent requests
- Added support for node.js 0.6's native clustering
- Removed simple-session library and replaced it with connect's session library backed by a redis store
- Reworked fileserver to serve index.html from memory and use compression when avaliable
- Added some windows support (although it doesn't bind to localhost)
- Fixed issue #2 for relative path bug when the domain name didn't have a / following it
- Removed compress library dependency in favor of the native zlib library that shipped in node 0.6
- Several small tweaks to support running on Heroku servers
- Added keyword and domain blocklists
- Pulled out configuration into a separate file
- Set up live demo at nodeunblocker.com
- Added "military" theme
- Added support for remote HTTPS servers.
- Created a simple-session library. (The ones I tried were all tied to bigger projects and/or didn't work well)
- Added basic cookie support via sessions.
- Urls that are relative to the root of the site are now processed in both html and css.
- Now only buffers last few characters if a chunk appears to end in the middle of a url.
- Added redirect support
- Added gzip support
- improved filters
