Javascript e Asp.net [Vb] webforms Session

Question

I have a javascript method that returns a string, In the case:

var hash = PagSeguroDirectPayment.getSenderHash();

how to put this hash variable in a Session and read this Session in Asp.

Dim hash as string =  Session("sessionDoHashExemplo").toString

or there is another way (without using post/get) to pass this information to Asp.

the above code is in a separate . js file, and I cannot use a Hidden input

Answer 1

Is not possible, Session's of server-side and client-side has no communication among themselves, The solution found was to allocate the results in hiddenfields and manipulate information through them.
