URL not resolving in IE

I am try开发者_C百科ing to open a url in IE that works fine in Firefox, but I get a Internet Explorer cannot display the webpage message. The url works fine in Safari, Chrome, and Firefox... It is not a live url currently and is using local host file but other calls to the same domain are resolving so I don't suspect the host file to be the issue. Here is the url segement that is causing issues.

/v1/sso/facebook/init?body=%7B%22verb%22%3A%22GET%22%2C%22payload%22%3A%7B%22hash%22%3A%22genusSSOLinkPop%22%2C%22loc%22%3A%22http%3A%2F%2Fdev.www.khou.com%2Fregister%3Fprofile%3D92da505591d%22%7D%2C%22callback%22%3A%7B%22success%22%3A%22bimreg.onloadlinksso%22%2C%22fail%22%3A%22bimreg.onfaillinksso%22%7D%2C%22auth%22%3A%7B%22token%22%3A%22d5de8efa8d8e66ce70f50781976ee033aac7e33e%22%2C%22nonce%22%3A%22f56e87594cbbd706ee9033cc049cba731f1b1ed5%22%2C%22session%22%3A%22MzU0ODMzN2U5ZjhhODQwMDAwNmUxOGVmZGUwZmY5NjMwN2VlNzhjNGMzOGE5NmVkZDQxMzk1YjM4MTk2NGVhMA%3D%3D%22%2C%22ts%22%3A%221296069789%22%2C%22sign%22%3A%22undefined%22%2C%22tp_sign%22%3A%22undefined%22%2C%22email%22%3A%22gwincr11%40yahoo.com%22%2C%22user%22%3A%221b87da2f9a993c2345353a14a3a01792afef51d5%22%7D%7D#easyXDM_genusSSOLinkPop_provider

Are there illegal characters I am not aware of?

Thanks, Cory

You're not showing the whole URL so it's hard to tell, but it might be related to this:

Maximum URL length is 2,083 characters in Internet Explorer

another possibility is that you're using the username@password:hostname scheme, which has been disabled in (I think) IE8.

internet explorer has URL limitation of 2083 characters. Other browsers can handle over 64 000 characters. Could this be the reason?
