How to add expiry date to external objects?

[Rocke]

I don't know if this is possible, but is there a way to determine expiry dates on external objects ?




I used this code on .htaccess, but it's still not working.

# No ETags
Header unset ETag
FileETag none

# Caching -- mod_headers
<IfModule mod_headers.c>

# 1 Year = 29030400s = Never Expires
<filesMatch "\.(ico)$">
Header set Cache-Control "max-age=29030400, public"
</filesMatch>

# 1 Month = 2419200s
<filesMatch "\.(css|pdf|flv|jpg|jpeg|png|gif|swf)$">
Header set Cache-Control "max-age=2419200, public"
</filesMatch>

# 2.5 Days = 216000s
<filesMatch "\.(js)$">
Header set Cache-Control "max-age=216000, private"
</filesMatch>
<filesMatch "\.(xml|txt)$">
Header set Cache-Control "max-age=216000, public, must-revalidate"
</filesMatch>

# 5 minutes = 300s
<filesMatch "\.(html|htm)$">
Header set Cache-Control "max-age=300, private, must-revalidate"
</filesMatch>

# Disable caching for scripts and other dynamic files
<FilesMatch "\.(pl|php|cgi|spl|scgi|fcgi)$">
Header unset Cache-Control
</FilesMatch>
</IfModule>

Nvm, please delete this post.

No, you can't add expiry headers to your externally hosted files.

thanks ProtoWorker, I guess I will need a CDN for that.
