Which means that only a small percentage of users wouldnt be able to use the feature. We find its pretty impressive to zip a large file before display and the users only notice the speed difference. I did find however using gzip compression at level 9 was a bit much and slower on the PC to decompress and that a compression level of 6 was a good balance between size and speed. mn Mark Nold markn@enspace.com <mailto:markn@enspace.com> Senior Consultant   Change is inevitable, except from vending machines. -----Original Message----- From: jeremy brand [mailto:jeremy@nirvani.net] Sent: Wednesday, November 22, 2000 3:14 AM To: Robert Collins Cc: PHP General List Subject: Re: [PHP] file compression That is true with some browsers. You can check the Accept-Encoding: (I think -- see the HTTP RCF for sure) headers. If it includes application/gzip, then is should be okay. But, keep in mind, this is not common practice, it adds overhead to your servers and introduces a major risk of your web site appearing broken to large percentage of your audience. -jeremy brand Jeremy Brand :: Sr. Software Engineer :: 408-245-9058 :: jeremy@nirvani.net http://www.JeremyBrand.com/Jeremy/Brand/Jeremy_Brand.html for more - - - - - - - - - - - - - - - - - - - - - - - - - I am pleased to see that we have differences.
