I assume you're referring to an integrated AutoVue solution. Is this for one of the Oracle VueLink integrations (e.g. VueLink for Documentum or VueLink for UCM), or is it for a custom integration using the AutoVue ISDK.
If it's for a custom integration using AutoVue ISDK, please refer to the AutoVue ISDK Technical Guide, specifically Section 7.3 ("Handling Markups"). It explains how to customize the response from your integration to the AutoVue server.
