Page speed insights tells me to enable compression for google-maps source. It recommends to use mod_deflate if using Apache. Well, I've put the next snippet code inside the .htaccess file:

<IfModule mod_deflate.c>
<IfModule mod_headers.c>
    Header append Vary User-Agent env=!dont-vary
</IfModule>
<IfModule mod_filter.c>
    AddOutputFilterByType DEFLATE text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon application/json
<IfModule mod_mime.c>
    # DEFLATE by extension
    AddOutputFilter DEFLATE js css htm html xml
</IfModule>
</IfModule>
</IfModule>

I've enabled mod_deflate (and automatically enables mod_filter), and mod_headers and mod_mime were already enabled.. But Page speed page still tells me to enable compression. What am I doing wrong, or what should I do?

This is a screen shot of page speed error:

can you please update question with screenshot from PageSpeed? I don't see any problems with your configuration. I've got similar and Google is reporting green status in my case. –  GioMac Sep 4 '13 at 1:56

Those are third party resources, and you have no control over whether they use compression or not (they will not, because doing so would potentially expose private data in a BREACH or CRIME attack). You can safely ignore messages suggesting compression of resources loaded from third party sites, and messages suggesting compression of content served via HTTPS.

All right. Thanks! –  Manolo Sep 4 '13 at 9:28
