After some more investigation I think that the problem is linked to the way Internet Explorer implements the XMLHttpRequest javascript object. This object is used by GWT to send the request. The link below explains the details of the issue.
http://www.vistaheads.com/forums/microsoft-public-internetexplorer-general/479422-xmlhttprequest-post-sometimes-fails-when-server-using-keep-aliv.html I'm thinking of implementing a workaround with a custom RequestBuilder. RequestBuilder.send() would start a Timer timing out after 300ms. On timeout it would abort the request and send a new request. Hopefully this will cancel IE's behaviour of resending the request with a missing body. Please don't hesitate to contribute if you've an idea or think this won't work.
