Tests support for compressing JavaScript from PHP.
Outputs JavaScript that tests if compression from PHP works as expected and sets an option with the result. Has no effect when the current user is not an administrator. To run the test again the option 'can_compress_scripts' has to be deleted.Funzioni correlate: wp_ajax_wp_compression_test, gzip_compression, comment_text, codepress_footer_js, force_ssl_content
