I'm facing an issue with the current application. In Internet Explorer 7 and 8, the request parameter map on the server is sometimes empty in ajax requests as well as form submissions (its not specific to any page and it happens in like 1 out of 50 times on any page). This happens in POST requests mostly causing error on the server side code and shows an error in the browser. Firefox and Chrome are both fine. Does anyone know of any issue with IE which causes it to not send POST request parameters to the server (maybe connection keep-alive has to do something with it). If IE was just aborting request it could be understood but it shows the response (the error) which is confusing.
