A HTTP/HTTPS Caching Proxy
Project description
Caching Proxy
CProxy (CP) is a HTTP caching proxy server written in Python 3. With the aim of being able to surf the Internet completely offline, it will intercept Browser's HTTPs requests and decrypt the the traffic on-the-fly to store each successful HTTP response.
This work is inspired by coursera-dl and edx-dl.
Installation
pip3 install cproxy
If you want to install CP manually, you should install the following packages
- pyOpenSSL
- brotli
- chardet
Or simple run pip install -r requirements.txt
in the package's home directory.
Usage
-
Run the program by executing
$ cproxy
-
Change browser's proxy setting to
http://loaclhost:8080
-
Visit "http://cp.ca" to install Certificate Authority (CA) (this is required. Otherwise you can only visit http websites off-line). For more detailed guidance, please refer mitmproxy - Certificates.
-
Viola, you can browse your favorite websites now.
-
When disconnected from the Internet later, you can still visit those websites off-line. Or you can explicitly tell CP to use off-line mode
cproxy -off
-
For more options, run
cproxy -h
$ cproxy -h usage: CachingProxy arguments [-h] [-cd CACHE_DIR] [-p PORT] [-off] [-d] optional arguments: -h, --help show this help message and exit -cd CACHE_DIR, --cache_dir CACHE_DIR where to store caches -p PORT, --port PORT server listening port -off, --offline Offline mode -d, --debug Enable debugging mode
TODOs
- Caching HTTP/HTTPS websites
- IPv6 support
- Pre-fetching
- Proxy (use proxychains for now)
- Youtube support (lots of edx's videos are hosted on youtube. For now, youtube will be blocked when you visit course.edx.org thus to force player to use other video sources)
