Security constraints

In order to be able to view and submit properly your own tests you need to have your browser's settings adjusted accordingly. Please read below for each case (read tests/submit tests) respectively.

View Page (view the tests)

For viewing the page with the Tests, there is no other user obligation other than using a compatible browser (IE has been tested thoroughly on this aspect already) and having JavaScript (also so-called “Active Scripting”) enabled.

In the following the reader can see pictures of how the security settings for the "Internet Zone" should be set.

There is no ActiveX or other plugin required. Everything transmitted is pure html and JavaScript.

Although everything is now based on the server-side to Asp.Net, our decision here was based only the resources and persons available to help us develop these pages. There is nothing special to .Net here, other than achieving easy user authentication, page state and some structuring of the underlying code. Let’s see how this frame will withstand users appetite for bandwidth:)

Submit Page (submit a test)

Here applies to a large extend what we have said above. With one notable exception. The user is required to use exclusively Internet Explorer as his browser and be more tolerant towards security. This is a technical requirement, because the format translation from each measuring application (C1/C2-PI/PO for the time being) has to be done on the submitter’s machine.

Since the time and resources required for this format transformation requires extensive resources both in time and memory, it would impractical to devote all this processing power on the side of the server.

We must make this clear to our users, so that to minimize the criticism from their part on the way we designed the submission page. Of course, we do accept this along any any other criticism. In fact we do encourage it. So, all this is said here for the purpose of saving some of time trying to clarify and answer identical or similar questions from the part of our users over and over again.

First, we must stretch the fact that some programs, like KProbe, in the case of DVD PI/PO measurement, produce text files of over 1 MB length! Posting them to our servers would be prohibitive anyway. I hope this argument by itself is enough for justifying the approach we adopted.

For all these reasons, a user will have to use IE 5.5 or higher for being able to submit tests. (IE 5.0 might suffice, but we have not tested this yet.) He will also have to enable “Active Scripting”, and relax some other security settings. For this reason the best approach would be to set the address “cdrinfo.com” at the list of trusted sites. Then he will have to verify that “Initialize and Script active X controls not marked as safe for scripting”, “Run ActiveX controls and plug-ins” and “Access Data sources across domains” are all set as either "enable" or "prompt".
