We are currently working on projects for various government departments. Our web application, which they are utilizing, incorporates the use of Ajax in certain areas, particularly to retrieve information regarding specific items that users click on.
Although they have permitted JavaScript in their staff's browsers, it appears that they block Ajax at their firewall or through other methods. Is there a way to replicate this restriction in IE or Firefox so we can test and adjust our code to provide alternative means of achieving the same functionality?
Even if we were to present a non-Ajax version to all users and then guide those with access to Ajax towards that version, we would still need to recreate the non-Ajax scenario for testing purposes in order to ensure that our branching code works effectively.
