Cache requests to upstream server forever

reqcache

Simple utility to proxy and cache all requests to upstream server. Useful when you need to benchmark microservice by self and exclude other services affects

Prepare to use

Just clone the repository and install dependecies:

npm install

Usage

node reqcache port baseUrl [debug]

Parameters:

• port - port to listen on
• baseUrl - base url to proxy requests
• debug - optional flag for printing debug info

Example

For example, run cached proxy for http://example.com, that uses resource /styles.css:

node reqcache 3030 http://example.com debug

Open in browser http://localhost:3030 and you will see in console something like:

Proxying to https://example.com at 0.0.0.0:3030
new request: GET /
response: /: 200
get from cache: GET /
new request: GET /styles.css
response: /styles.css 200
get from cache: GET /styles.css

Then reload page in browser:

get from cache: GET /
get from cache: GET /styles.css

Reqcache memorized first response and just return it again with no requests to upstream server.
