Google Pagespeed and CDN

[Ljubomir Lukic]

I am using the Rackspace CDN service (Akamai), and I have updated the pagespeed configuration (domain name) to use the pagespeed. In the insight the overall score had drop down because pagespeed was not optimizing all of the images that are delivered from the CDN. For example on homepage it has optimized the all of the small images, but those that are in the main carousel did not, I just do see the reason why, because all images exist in CDN and all images are delivered from CDN.
If I configure pagespeed not to use CDN but to pull the media content from the local server, everything works well.

My Pagespeed configuration is:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

ModPagespeed on
ModPagespeedInheritVHostConfig on
ModPagespeedFetchHttps enable

AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html
