Support for POST preservation when APM Multidomain SSO is configured

Hi Yann,

I tried to apply your code for a customer but I faced some limitation.

This code only works for the first request starting session.

I had the following behavior :

• user request sharepoint website (not authenticated yet) with GET --> redirect to login page
• user request login page with GET and authenticate --> redirect to sharepoint website
• user want to edit with Office Web App behind APM, first request is a POST --> redirect to login page
• user request login page with GET (already authenticated) --> redirect to Office Web App
• browser send a GET request --> file edition fails
• user refresh content --> file edition fails

I tried this code but session.server.body is only set for first request starting the session.

did you ever get this issue? did you try to solve it?
