I don’t think that’s the same thing though. I’ve always enabled mod_deflate in .htaccess, but the URL I posted is actually saving CSS and JavaScript files with the .js.gz and .css.gz extension. It’s compressing it and serving it compressed all the time, and the compression is only happening once. Whereas, with mod_deflate, it still has to call the uncompressed file, compress it, and then serve it.
