Ok, I have a possible idea for an add on / improvement that DNN can make... Im not sure how feasible it is, but it should help increase the download speed of most DNN sites...

Most browsers only allow two concurrent connections to a domain at a time.  I used FireBug to look at one of my smaller pages and found that it had downloaded over 60 files.  About 20 of these were JS or CSS files and there were about 40 images.  The page I was looking at had two 3rd party modules that made heavy use of js.  I know that there really isn't a good way to combine all of the CSS files and all of the JS files... but if there were a way to fully qualify the source URLS with a separate domain, or a subdomain then more concurrent connections could be created (thus reducing download time).  For example adding js.mysite.com would open up two more concurrent connections just for javascript.  Also add subdomains for css and images and that would bring the site up to 8 concurrent connections that it could be used.

I don't think it would be too tough to add fully qualified URLs to the images, css, and js files.... but is it possible to create these subdomain aliases inside DNN without actually adding the subdomains to the hosting provider. 

Let me know your thoughts!!

Thanks, Dave

Dave,

I am not sure how feasiable that is due to the setup required in IIS and other third party configurations needed to make it happen.

However, if you are looking to reduce the number of HTTP requests I would strongly recommend looking at Snapsis' PageBlaster as it has JS and CSS merge capabilities as well as advanced caching which can greatly improve site load time.
