CacheBrowser has been merged into our new censorship circumvention tool called MassBrowser. Please visit the MassBrowser project's website and its git repository.

The current CacheBrowser software is a research prototype implementation, and is not yet ready for end-users. If you are a researcher or developer check it out and give us feedback, otherwise please be patient while we work on an end-user version of the code. Thanks for your understanding and support!

• Installing CacheBrowser
• Bootstrapping
• Commands

pip install cachebrowser

To run the CacheBrowser process simply enter the cachebrowser command

cachebrowser

You can then use CacheBrowser by using the CacheBrowser plugin for your browser or by setting the HTTP and HTTPS proxy on your browser to localhost:8080

In order to be able to browse a page using CacheBrowser, the page must first be bootstrapped. What this means is that CacheBrowser must first find out what CDN the page is hosted on and also obtain some edge server addresses for that CDN.

CacheBrowser supports local and remote bootstrapping sources. Local bootstrapping sources are files in YAML format which provide bootstrapping information for hosts and CDNs. Remote bootstrapping sources are RESTful services which provide bootstrapping information through HTTP requests.

Any number of local or remote bootstrapping sources may be defined in the CacheBrowser configuration file. When bootstrapping a host or host, CacheBrowser will go through the provided sources in the specified order until the information is found.

Bootstrapping sources can be specified in the configuration file using the bootstrapper_sources key, for example:

boostrapper_sources:
	- type: local
	  path: local_bootstrapper.yaml
	- type: remote
	  url: https://bootstrap.cachebrowser.net/api

A local bootstrapping file is a YAML file containing a list of Host or CDN information.

For example:

- type: cdn
  id: akamai
  name: Akamai
  edge_servers:
    - 23.208.91.198
    - 23.218.210.7

- type: host
  name: www.nbc.com
  ssl: false
  cdn: akamai

- type: host
  name: www.bloomberg.com
  ssl: false
  cdn: akamai

For each CDN provided in the bootstrapping file the following information should be provided:

For each Host provided in the bootstrapping file the following information should be provided:

You could also run a command with CacheBrowser:

cachebrowser <command>

These are the valid commands you could give:

cachebrowser bootstrap www.nbc.com
cachebrowser get http://www.nbc.com

cachebrowser get https://www.istockphoto.com 69.31.76.91
