Well... the 1st step to debug is putting all things in the rigth side. png images still not full optimized becasue it have transparent pixels or are sensitive to compression noise, but are optimized by IPRO. You can see it because the eTag header: `Etag: W/"PSA-aj-nbqpw_qrXQ-br"` , these etag header is set by IPRO, you can se that Conten-legth and X-Content-legth mismacht, these are the result of partial optimization, IPRO don´t rewrite the url. About the js and css files, can you try to set: `ModPagespeedModifyCachingHeaders on` And find from where comes this header (see the image), there is a no-cache header  ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
