Apache htaccess file for .ipa files

To allow my customers to download my iOS apps signed with AdHoc or Entreprise certificates, I use this htaccess file:

<FilesMatch "\.(ipa|plist)$">
 FileETag None
 <ifModule mod_headers.c>
 Header unset ETag
 Header set Pragma "no-cache"

AddType application/octet-stream .ipa
<Files *.ipa>
 Header set Content-Disposition attachment

The “Caches” directives are not mandatory, but large customers are usually behind a reverse proxy and I want to avoid side effects, if possible.

So far, so good.
