Apache Developers: auth-int in Apache2

[venky]

Hello all im new to this forum. Please redirect me, if i'm not posting in the right place.

Im trying to achieve auth-int functionality with Apache2. Apache currently does not digest the entity-body for auth-int. In my application i need to customize apache to digest the entity-body & compute the auth-int. Some references online suggested writing input filters but the filters dont get called before the Authentication is done. Im stranded without info.

Can one of you help?
