lightproxy is a lightweight HTTP reverse proxy written in Golang aims to accelerate responsing. It caches web resources in main memory and implements a non-blocking design, so providing lightning fast speed.
lightproxy takes a rather conservative strategy in deciding whether to cache a certain resources, rules including:
- requests of types other than GET are never cached
- URLs containing query strings are not cached
- if a Set-Cookie header was found in response, the corresponding URL is not cached
clone the code:
git clone https://github.com/wyage/lightproxy.git
build the code:
cd lightproxy
on Windows:
build-win.bat
on Unix-alike:
./build.sh
Before you start the build step, please make sure the go executable file is accessible.
Then you need to edit the bin/config.json, point the value of "BackHost" to your own web address.
After this, you can start it, run bin/lightproxy.exe on windows or
bin/lightproxy on Unix.
On Windows 7 Professional,
######1. start a web server first:
godoc -http :9009
######2. run our proxy program:
lightproxy.exe
######3. run benchmark against backend server:
ab -c 100 -n 10000 http://127.0.0.1:9009/pkg/
