Browserman, the tool to make MITM attacks on browsers more interesting.
Because people still think making a form that was served over HTTP submit
to an HTTPS URL makes stuff secure.

This software consists of two components:

 - the hoxy part injects a <script> tag (or three, to be precise) into every
   http page that goes through it (it's a transparent proxy)
 - the jssrv part handles everything afterwards

Getting the requests through the transparent evil proxy in the first place is
your job.
