I have a web-page which content must be constructed on the fly. When user clicks some parts of the web-page, it must load information from the file which is placed on the server in the same directory along with web-page into special content <div>.
As far as I get it, with JavaScript, I must use ajax technology so I have a question: should I configure server so that he can handle ajax requests specifically, or is it just simple GET over HTTP request which should be supported by any web-server anyway?
And my second question - if ajax is technology, which will work out only if server is properly configurated, can I do what I need by simple GET from JavaScript somehow?
Also, if it is easier to use server-side scripting, how can it be done by VBScript?
AJAX requests are very much like usual HTTP requests. So you do not need to configure your server in any special way to make them work. A usual server should already support at least GET and POST requests.
One thing, that might be important for you, however, is, that as long as there is no other "protection" for the files, everyone can access them directly, too. So in case the AJAX-loaded content contains some kind of user sensitive data, you should put some access control in place!
