• Using CGIWrap. Here is the URL using CGIWrap
  
  http://www.cs.fiu.edu/cgi-bin/cgiwrap/~downeyt/test_file_write.cgi
  
  • Go to the cgi-bin of the www.cs.fiu.edu server
  • Execute the script cgiwrap
  • Pass two parameters to the script
    • ~downeyt, the root directory of the owner of the script
    • test_file_write.cgi, the name of the script to run in the user's directory
  • In order for CGIWrap to work on mongoose, the script to run must be placed in the public_html/cgi-bin directory of the user's root directory. The directory only needs rwx for downeyt, or for your account if it is your script.
