On your home page http://www.ulteo.com/home/en/home?autolang=en Currently the following files could be compressed: (19.1K) http://www.ulteo.com/home/en/home?autolang=en. (126.1K) http://www.ulteo.com/home/_default-static/js/lib/prototype.js (5.7K) http://www.ulteo.com/home/_default-static/js/lib/shortcut.js (5.8K) http://www.ulteo.com/home/_default-static/js/class_utils.js (2.9K) http://www.ulteo.com/home/_default-static/js/global.js (2.8K) http://www.ulteo.com/main/js/tooltips.js (11.5K) http://www.ulteo.com/home/_default-static/css/styles.css (1.7K) http://www.ulteo.com/home/_custom-static/css/menu.css (1.8K) http://www.ulteo.com/home/_custom-static/css/global.css (3.8K) http://www.ulteo.com/home/_custom-static/css/content.css Your server is Apache/2.2.3 so see the following page for details how to configure it at: http://httpd.apache.org/docs/2.0/mod/mod_deflate.html This should reduce by about 70% your data transfers (in this particular case 181K becomes 55K). Move all your CSS stylesheets to the top of the HEAD element for all your web pages. This allows progressive page rendering, making something appear on the screen sooner. For more ideas and justifications see: http://developer.yahoo.com/performance/rules.html The extra CPU effort is more than compensated by the reduction in the amount of data being served (your mileage might vary).

I have a few questions: - it seems that all browsers don't support gzip uncompression, so does it mean you have to do some exceptions for particular browsers that wouldn't support it? - does Apache keeps compressed contents in cache instead of compressing it for each HTTP request?

Just released! http://www.ulteo.com/home/ovdi/openvirtualdesktop You can even plug it to a CIFS fileserver and Active Directory.

Most of the time, it's because the reverse DNS name is not well configured, so they get "blacklisted" when the Session Server checks reverse names from Application Server's IP. When it happens for Application Servers, three fixes are possible: - either you disable the reverse DNS check in the admin console - or add an exception for each application server in the admin console - or set the DNS server with correct reverse names (recommended) When it happens for the Session Manager, the only way to fix it for now is to set correct reverse DNS server entries. We are going to improve the documentation about this issue and add increase verbosity in the admin console.
