Impostazioni mod_deflate e mod_header?

Question

Ho finalmente ottenuto un account di hosting VPS che mi permette di usare mod_deflate e mod_header (ovviamente). Sto tentando di rendere più veloce il mio sito grazie alle linee guida di YSlow che includono gzipping (tramite mod_deflate) delle pagine e impostazione di un'intestazione di scadenza lunga.

Quale sarebbe il codice .htaccess per questo? Ho visto vari esempi, ma mi chiedo come apparirebbe per questi parametri.

Ad esempio

# Mod_deflate 
<IfModule mod_deflate.c> 
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript 
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|iso|tar|bz2|sit|rar|png|jpg|gif|jpeg|flv|swf)$ no-gzip dont-vary 
BrowserMatch ^Mozilla/4 gzip-only-text/html 
BrowserMatch ^Mozilla/4\.[0678] no-gzip 
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html 
Header append Vary User-Agent env=!dont-vary 
</IfModule>
