SoapHttpClientProtocol inherited class, persistence

[Yasel Prado]

Hello,
I have an ASP.NET application which have a class (lets say X) that inhertis
from SoapHttpClientProtocol, after initialize an object of this class X, I
need to maintain the session alive, to do so, i pretend make this object
persistent, keep the SOAP session information and recreate the object when
needed to use its methods; so the other peer wont be aware of what is
happening in this side.
Can I do this? if not, can someone suggest a way to keep a SOAP session live
for long time?
Best regards
