Thread:Project:Support desk/POST data lost during redirecting

Hi, I am creating an extension handling data sent by an external application. Data are sent via POST method. If the user is not logged in, I forward him into LogIn page using this code http://mediawiki.sourcearchive.com/documentation/1:1.14.0-1/classEditPage_7eca8a4db7d21663be3a691ad7cfdabe.html

Unfortunatelly, the POST data get lost during this operation. Is there any possibility how to LogIn while having POST data still available?
