Heroku Deployment - Githubissues

Hi,

I am a newbie to Golang. My applications needs to be deployed on heroku like a page that lets users upload a list of domains and then run "subjack.go".

I am not sure how to integrate the user input domain list into your "subjack.go" file

I would appreciate it, if you could give some suggestions.

Subjack.go (modified to my understanding) : Added a handle function for fileupload. But how do I make use of the user input file into your process function?!
