AutoResponder rewrites URLs instead of returning file contents

[Ilya]

Rule: regex:(?insx)\/0Pl5sssO4/.+\.js$ #script.js
and selected a file on a file system in the second combo-box 

I would expect that the AutoResponder would respond with the file contents, instead, it rewrites URLs to 

GET http://XX.XX.43.176C:\Users\chernyakov\Desktop\script\static.js/ HTTP/1.1
Host: XX.XX.43.176C:\Users\chernyakov\Desktop\script\static.js

All other headers are seem to be fine 

Is that a bug, or I am configuring it wrong ?
