The code then invokes the web service providing the names of callback functions to invoke for success or failure. Web browsers limit the number of simultaneous connections they make back to the server, typically to two. So, if you have a lot of ScriptReference elements in a page, you may want to consider having some select ones rendered inline to avoid contention for multiple concurrent requests to download the proxies.

However, the tradeoff is that inline scripts are not cached by the browser and bloat the size of the page. Large, frequently used scripts should be external references to take advantage of browser caching. The third argument passed to the proxy for invoking the web service is called the userContext. It is not sent to the server but is passed to the completion callback function. This allows you to carry extra data to your callback that is not involved in the web service call without consuming resources to roundtrip it to the server.

Even code that runs correctly almost all of the time can encounter something unexpected. Listing from ThrowError. If an error is encountered and an exception thrown, or if the timeout is exceeded, the error callback is called instead of the success completion function.
