Switching to a pure tomcat setup

Today I transfered our website to some new servers. I decided run a pure tomcat setup without apache in front. The problem is that the apache server did some critical and some less critical stuff that I haven't tried doing with just tomcat before (I've written the corresponding apache module in parenthesis):

• SSL (mod_ssl)
  
• Url redirection, critical for url canonization (mod_rewrite)
  
• Gzip compression (mod_deflate)
• Setting the correct cache-headers (mod_expires, mod_headers)
