I'm a web hoster in shared hosting and i have a request which will help my users and yours in same time.
The mime type of your file :
isn't correct because it's return the mime type : [application/octet-stream]
curl -I http://fr.wordpress.org/wordpress-3.5-fr_FR.zip 2>/dev/null | grep 'Content-Type' Content-Type: application/octet-stream
And in "octet-stream" it's not possible to cache it with a proxy like squid example.
I host several WordPress on the same IP adress in shared hosting and each website try to download each time your file. So my request will help your servers against a very load of download and increase the security update for my customers and yours.
You didn't make this error for other files like example : http://wordpress.org/extend/themes/download/max-magazine.1.0.3.zip
where the mime type is : [application/zip]
curl -I http://wordpress.org/extend/themes/download/max-magazine.1.0.3.zip 2>/dev/null | grep 'Content-Type' Content-Type: application/zip
Could you solve this problem and change [application/octet-stream] to [application/zip] please ?
This will help everybody in our downloads :)
Thanks so much,
