Ok, I have a weird array of objects as output of itertools and I need an array of strings... 1 - Convert the array to string 2 - Clean it up with regex and replace 3 - Convert the string to array 4 - Problem solved

This developer was trying to force the browser to download a custom image rather than show it inline, so he coded an open reverse proxy and attempted to release it to a production web app. Also, all exceptions are trapped and shown to the user in plaintext in their browser.
