How do I do multi-domain https with mod_wsgi? - django

Question

I'm a developer and a bit of an apache novice and I'm trying to transition a bunch of our Django https servers to mod_wsgi, which previously used mod_python:
<VirtualHost *:443>
ServerName *.example.com
SSLEngine On
SSLCertificateFile /etc/ssl/star_example_com.crt
SSLCertificateKeyFile /etc/ssl/star_example_com.key
SSLCertificateChainFile /etc/ssl/DigiCertCA.crt
UseCanonicalName Off
VirtualDocumentRoot /var/www/%0
<Directory "/var/www/foo.example.com">
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE example.foo.settings
PythonPath "['/home/django'] + sys.path"
PythonDebug on
</Directory>
<Directory "/var/www/bar.example.com">
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE example.bar.settings
PythonPath "['/home/django'] + sys.path"
PythonDebug on
</Directory>
</VirtualHost>
This allows us to run several https sites on the same physical server (ip). Adding a new https host simply involves adding a new <Directory> section, and creating the corresponding directory under /var/www/.
The closest I've gotten is by using
<Directory "/var/www/bar.example.com">
SetHandler wsgi-script
Options ExecCGI
</Directory>
and creating /var/www/bar.example.com/bar.wsgi, then I can access urls like https://bar.example.com/bar.wsgi/...rest..of..path..
I haven't been able to find a directive (that can be used inside <Directory>) that is equivalent to WSGIScriptAlias when the target is a file-path, like we're using for the non-https sites:
<VirtualHost *:80>
ServerName bar.example.com
WSGIScriptAlias / /home/venv/upgrade/example/bar/bar.wsgi
<Directory "/var/www/bar/">
Order deny,allow
allow from all
</Directory>
</VirtualHost>
Which allows us to go to http://bar.example.com/...rest..of..path.. (ie. no bar.wsgi prefix).
Is it possible to get rid of the bar.wsgi part in the https url?
[Solution:] (based on #GrahamDumpleton's link):
<Directory /var/www/bar.example.com/>
Options ExecCGI Indexes FollowSymlinks
AddHandler wsgi-script .wsgi
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /bar.wsgi/$1 [QSA,PT,L]
Order allow,deny
Allow from all
</Directory>
works beautifully.

This is covered in:
http://code.google.com/p/modwsgi/wiki/ConfigurationGuidelines#The_Apache_Alias_Directive
See the bit towards the end of the section where shows use of mod_rewrite and an application wrapper to do fixups of SCRIPT_NAME.
