One way to avoid accidentally including the same script twice is to implement a script management module in your templating system. However, nested complex types those defined internally within another type are not made available to the client as standalone objects by default. Filtering data sent from the AutoCompleteExtender control.

You'll see how to use nested complex types later in the article. In some situations it's not easy to move scripts to the bottom. Move the mouse over a thumbnail to view the larger version. In Internet Explorer, the script may be deferred, but not as much as desired.

The Apache modules help out by adding appropriate Vary response headers automatically. This is the most important guideline for improving performance for first time visitors. Using the ScriptMethod attribute with the ResponseFormat property. Obfuscation is an alternative optimization that can be applied to source code. The AutoCompleteExtender control can be used to extend existing functionality of a textbox and help users more easily locate data they're looking for.

The Last-Modified header validates based on the component's timestamp. But there are other variables that affect response times.

One of the most wasteful redirects happens frequently and web developers are generally not aware of it. The enlarged image can be a different image from the original, so the former is loaded only on demand when requested. Once the toolkit assembly has been added, you'll want to reference it in web. For example, the server with the fewest network hops or the server with the quickest response time is chosen. Although using redirects in these situations reduces the complexity for developers, it degrades the user experience.
