Hello ranchers,
I am using ajax in my web application, when a xmlhttp get request is sent, insdide the doGet method, is there any difference how the httpServletRequest object behaves? Can i acess session etc from the servlet when the request is xmlhttprequest?

Any response would be appreciated,

No

Xmlhttprequest is a browser/javascript side concept.

The server just sees a normal httprequest to be processed like any other GET or POST. I suspect that the request headers may have extra significance but it is up to you the programmer to check those headers.

Bill thanks for the response . I have a list that needs to be displayed on the page dynamically, using ajax. So i wanted to put it in session scope, so was thinking will i be able to do access session scope from the servlet on a xmlhttprequest.

Yes. As was already pointed out, the fact that the request was initiated as an Ajax request is transparent to the server.

Bear, I was just trying to explain what i was trying to do.I did understand that i will be able to do that from Bills response. Probably should have phrased it differently . Thanks anyways.

OK, cool. Sounded like a question and I wanted to make sure things were clear.

For some reason, a lot of people out there think that you can't use Ajax in conjunction with Servlets and JSP and that, of course, is complete nonsense.
