YSlow Best practices with Django applications, how to implement them?

Question

I have a django 1.1.1 application, actually in development, thinking of best practices. I tested the YSlow test (used by Erade E: ESlow V2), it recommends:

Grade F on Addition Expires Headers

     

- There are 37 static components with no expiration date.

     

Grade F on the use of a content delivery network (CDN)

     

- There are 37 static components that are not on the CDN.

     

Estimating F on gzip compression components

     

- There are 17 simple text components that should be sent compressed

How can I implement it using Django?

More context: Python 2.5, deployment in webfaction

Example:

Grade F on Make Less HTTP Requests

-. , Linux/Apache:

<IfModule mod_deflate.c>  
    AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-javascript text/javascript text/css application/javascript  
</IfModule>  

Expires mod_expires:

>cd /etc/apache2
>sudo ln -s ../mods-available/expires.load mods-enabled/expires.load

MIME, :

# edit /etc/apache2/sites-available/default  
ExpiresActive On  
ExpiresByType text/css "access plus 12 hours"  
ExpiresByType application/javascript "access plus 12 hours"
