Looks cool, but safari reports to not support gzip even though it really does. Here's a URL (comment #2) that describes what's happening:<div><br class="webkit-block-placeholder"></div><div><a href="http://joseph.randomnetworks.com/archives/2006/07/13/compressed-javascript/">http://joseph.randomnetworks.com/archives/2006/07/13/compressed-javascript/</a></div><div><br class="webkit-block-placeholder"></div><div>-Tom</div><div><br><div><br class="webkit-block-placeholder"></div><div><br><div><div>On Jan 17, 2008, at 9:17 PM, Matthew Nuzum wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">It's trivial to write a bit of PHP code that looks at the http accept-encoding header and choose to send either compressed or uncompressed data based on what you find there.

Also, it allows you to use normal, non-packed js files with practically no difference in download size which makes debugging js *so* much easier.
