Have you more than two (jquery and jquery-ui), then you have too much. You can save much place and performance by using Content Delivery Network (CDN) links for the resources like javascript, css, fonts and icons. Consider those Content Delivery Networks:
CDN for custom resources
But can we benefit from this CDN concept for our custom resources? I think so, if your farm has ten thousands of site collections, and you deploy javascript files, css files in the Style Library, it would be great to eliminate resource duplicates. So my thougt is to deploy resources to one place. It could be:
- An external web application static.contoso.com like many web applications do
- A dedicated site collection for resources cdn.contoso.com with Anonymous access
The CDN concept in Office 365
Have you noticed that Office 365 uses cdn links for almost all SharePoint javascript files that traditionaly were referenced from the _layouts folder
With this I want to raise a question. What do you think about the CDN concept within SharePoint? Have you used it? Have you plans to have it?
