This creates a requirement that for every action, the client must poll the server, instead of listening, which incurs significant overhead. This overhead leads to several times higher latency with Ajax than what can be achieved with a technology such as websockets.
A workaround implemented by Ajax techniques is to change the URL fragment identifier the part of a URL after the " " when an Ajax-enabled page is accessed and monitor it for changes. Solutions to this problem exist, many of which again use the URL fragment identifier. Nevertheless, the solution provided by HTML5 for the above problem also applies for this. For example, editing a search field may trigger a query to the server for search completions, but the user may not know that a search completion popup is forthcoming, and if the Internet connection is slow, the popup list may show up at an inconvenient time, when the user has already proceeded to do something else.
The web api must remove all trace of the data once it returns the PDF.
So a single POST would be ideal. There are other threads on stackoverflow that debate why it is bad to push data in the body of a GET, and since that violates some standards, that is off the table. Also the data submitted must be secure - submitted via https, so putting it in the URL is no good.
I figured out the dual posting from the form, the same data is submitted to my Web API on a submit - to change the devices settings, and on a button click to generate a PDF.
That window receives a block a text that is returned from the Web API that is there for debugging. Book details Author: Thomas A.
