Hi

I use IIS to hosting Django web site ! I always meet the below problem!!

----- log begin -----

Error occurred while reading WSGI handler:

Traceback (most recent call last):
  File "c:\program_files\anaconda3\lib\site-packages\wfastcgi.py", line 791, in main
    env, handler = read_wsgi_handler(response.physical_path)
  File "c:\program_files\anaconda3\lib\site-packages\wfastcgi.py", line 633, in read_wsgi_handler
    handler = get_wsgi_handler(os.getenv("WSGI_HANDLER"))
  File "c:\program_files\anaconda3\lib\site-packages\wfastcgi.py", line 605, in get_wsgi_handler
    handler = handler()
