xmlHttp.status 404 I get 200 on my dev server and 404 on my qa

[wkerplunk]

I am getting two different xmlHttp.status codes back from two different servers with the same files on each server. What should I check?

xmlHttp.status 404 on the qa server doesnt complete request

xmlHttp.status 200 on the dev server all is great.

Any Ideas what could be missing?

The first thing to check is if the page works without Ajax. If you type the URL that you use in the open() method in the address bar (if using GET) or submit to (if using POST), does it give the expected output?

If you are using a httpHandler make sure you have added the POST verb or all (*) in web.config.
Examples: add verb="GET,HEAD, POST" or add verb="*"
