I have a page which writes some data for display to a page. The user can then browse to another page which displays a different, related set of data. The transition works fine except for when the Querystring exceeds about 2048 characters. In this case, the button simply doesn't work with no error. Does anyone know if the querystring property has a max size or if there is some setting in IE or IIS that would prevent the data from posting? Any help would be appreciated. Thanks.
