The 'enhanced vmxnet' device is only available in ESX 3.5 and that is the one change that brings the best performance improvement, so the best advice I could give would be to upgrade ESX!

They use Zeus servers. When I uploaded the site I submitted my URL to google. Google came back with errors: http://www.coloursense.net/index.html 404 (Not found) Help Mar 10, 2008 I looked into the problem more and received this email back from google forums: ----- Why index.html shoudl also give a 404 is the problem. It exists, it returns a 200. Maybe it was a one-time error, soemthign wrong with the server on that day. Even though index.html exists OK, it shouldn't be used in navigation and should be 301 redirected to the root, to take care of anybody trying it or old bookmakrs or old cached urls. Matter of cleaning up navigatin and keeping only one url for each page of content. Yes, the actual default page may well be called index.html and its content will be shown when you request the domain root url. But it is also shown when you request domain root url AND index.html - thus you have 2 urls that show the same content. Robots don't know it's the same physical file - they don't care. it's 2 different urls shwoing the same exact content, thus duplication. I am referring to redirecting so that the URL will be just that of the domain root url. This goes together with ensuring you don't use index.html in navigation but always just the domain root url. ------- How can I use a .htaccess file to redirect the http://www.coloursense.net/index.html to the root? I have spent a week trying to find out, I have no real experience in sorting this out.. could you help please!!! Thanks rob

How can I use a .htaccess file to redirect the http://www.coloursense.net/index.html to the root?

There is a virtual server-specific configuration option, webcache!control_out, whose value will be added to every cached HTTP response for the given virtual server as the Cache-Control header. This can be configured in Virtual Servers > NAME > Content Caching . Note, however, that there is no guarantee that up-stream proxies respect this setting (well-behaved ones do, of course).

This capability is driven by TrafficScript, so it's only accessible in the full ZXTM product. See http://www.zeus.com/products/zxtmlb/features.html for a more detailed list

Or am I being dense?

If you're having trouble getting a rule to run, drop a line to our tech support team.
