 A JVM agent that automatically forces a proxy for HTTP(S) connections, and trusts a given additional HTTPS certificate authority, for all major JVM HTTP clients.
 
-This agent lets you intercept all HTTP(S) from any JVM application automatically, with no code changes, so you can inspect, debug & mock this traffic using an HTTPS proxy, such as [HTTP Toolkit](https://httptoolkit.tech) or any other HTTPS MitM proxy.
