How to use MECHANIZE in a FLASK project?

Question

Flask

Python 2.7.11, Windows 2008 R2
Inside a Flask project, I use Mechanize to get data from another site.
When testing, everything works, but as soon as I deploy to IIS, the record drops when loading an external site through Mechanize:
response = br.open(url)
Maybe IIS puts some kind of bans?
When tested (python app.py - localhost:5000) no problem

Received error:
Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Answer 1

Solved by calling requests.get('localhost:8000/script_mechanize.py')
where localhost:8000/script_mechanize.py script containing mechanize raised on CGI
