IIS 8.5 redirection not working as expected

hello,

we have migrated our web applications iis 6.0 [.net 2.0] -> iis 8.5 [.net 4.0] , facing issue 'redirection' supposed happen. 

the redirection url has query string params , picked fiddler : 

http://<servername>/<virtualdirectory>/xxx/xxx/<pagename>.aspx?value1=dummy?value2=dummy2&value3=dummy&exitredirectpage=<<pagename>>&role=xxxx&cred=xxx

the url throws exception , doesn't load page. however, if replace '?' in query string, page gets loaded without issues. so, if replace url with 

http://<servername>/<virtualdirectory>/xxx/xxx/<pagename>.aspx?value1=dummy&value2=dummy2&value3=dummy&exitredirectpage=<<pagename>>&role=xxxx&cred=xxx

it works fine.

on checking same url in iis 6.0, fiddler gives same url first 1 , loads properly.

so, wanted  check if specific needs handled redirection? there's been no change in code on migration , thing changed target framework.
