jmarantz commented on issue #1570: PageSpeed could not optimize (Proxy_pass) if response returned 200 URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1570#issuecomment-395640868 I think I wouldn't call this a bug. PageSpeed can't optimize resources that are served by origin with a validator like if-modified-since. You could argue that if you turn on the delivery of that header, PageSpeed should not optimize it. However, since PageSpeed already cached the version of the resource that had no validator, it has the right to use the second request to initiate the optimization, and the third request to serve the optimized content.
