Hello,
Interesting. I don't see anything of consequence in the Apache config
regarding CGI (unless I shouldn't be loading mod_cgi?)
a...@mmdev0:~/www/cgi-bin/foobar$ grep -rn cgi /etc/apache2/*|grep -v
sites-available
/etc/apache2/apache2.conf:145:#ErrorDocument 404 "/cgi-bin/
missing_handler.pl"
/etc/apache2/apache2.conf:202:DirectoryIndex index.html index.cgi
index.pl index.php index.xhtml
/etc/apache2/apache2.conf:339:# To use CGI scripts outside /cgi-bin/:
/etc/apache2/apache2.conf:341:#AddHandler cgi-script .cgi
/etc/apache2/mods-available/cgid.conf:2:ScriptSock /var/run/apache2/
cgisock
/etc/apache2/mods-available/cgi.load:1:LoadModule cgi_module /usr/lib/
apache2/modules/mod_cgi.so
/etc/apache2/mods-available/cgid.load:1:LoadModule cgid_module /usr/
lib/apache2/modules/mod_cgid.so
/etc/apache2/mods-enabled/cgi.load:1:LoadModule cgi_module /usr/lib/
apache2/modules/mod_cgi.so
/etc/apache2/sites-enabled/000-default:6: WSGIScriptAlias /foobar /
var/www/aj/cgi-bin/foobar/baz.py
So on your suggestion, I moved the script to a different location:
mmdev0:/var/www/aj/foobar# ll
total 4
-rwxr-xr-x 1 root root 253 Mar 6 16:12 baz.py
Here's the new Apache config:
a...@mmdev0:~/www/foobar$ cat /etc/apache2/sites-enabled/000-default
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmas...@localhost
DocumentRoot /var/www/
#WSGIScriptAlias /foobar /var/www/aj/cgi-bin/foobar/baz.py
WSGIScriptAlias /foobar /var/www/aj/foobar/baz.py
CustomLog /var/log/apache2/access.log combined
ErrorLog /var/log/apache2/error.log
LogLevel info
</VirtualHost>
And the results in the log:

So it works now...but still baffled about the significance of the
directory being named cgi-bin when there are no other script aliases
defined? So I disabled the cgi module, and restarted again (all other
things equal), and the test script works in it's current spot. I then
revert back to the original WSGIScriptAlias and location in cgi-bin,
reload Apache, and *now* I get prompted to download the .py file. So
there's definitely some dependency on "default" settings in mod_cgi.
Still not satisfied with my findings.
So here's a new configuration I tried:
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmas...@localhost
DocumentRoot /var/www/
WSGIScriptAlias /foobar /var/www/aj/cgi-bin/foobar/baz.py
#WSGIScriptAlias /foobar /var/www/aj/foobar/baz.py
<Directory /var/www/aj/cgi-bin/foobar>
SetHandler wsgi-script
</Directory>
CustomLog /var/log/apache2/access.log combined
ErrorLog /var/log/apache2/error.log
LogLevel info
</VirtualHost>
It seems that using the SetHandler directive in conjunction with a
WSGIScriptAlias permits the use of the cgi-bin directory. This logs
the following:

Fine. Wonder what happens when I re-enable those other two modules?

Still works. Guess that's the magic formula?
Eventually I will completely migrate off of and disable mod_python but
for a period of time, I will have to maintain both. It sounds like
you've seen issues with this though? Maybe I'll have to migrate a
server at a time...rather than a virt host at a time?
Thanks,
