Flask API

Function send_file

cache_timeout – the timeout in seconds for the headers. When None (default), this value is set by get_send_file_max_age() of current_app.

thekingofkings commented 8 years ago

The parameter cache_timeout of function send_file does not work.

    response.cache_control.max_age = 300
    return response

make_response cache_control object
