6.Q:What advantages and disadvantages can we find in Ajax?
Usually the pages in a website have the same type of content which has to be reloaded every time a request is made if we used the classical methods. Things improve when we use Ajax because only the content that requires updating will be sucessed . This will mean less loading time and less used bandwidth. The user interface will become more interactive and the section of web pages will become reloadable each alone all this due to asynchronous request usage.

In most cases we will have to disable the AJAX extension, but in rare cases we can fix the issue by using the setting sendContentLength to false. Also XDdebug can create some issues but they can be fixed by the activating the extension.
