>>OK. AFAICS none of the above are request/page specific (i.e. they are global and don't change from hit to hit) ? If that's true then we're back to something I suggested earlier. Just change your oResponse and oRequest properties in your framework class so that they reference the current request:
>>

>> Public Property oResponse
>>    Get
>>      Return HttpContext.Current.Response
>>    End Get
>>End Property
>>
>>Public Property oRequest
>>  Get
>>     Return HttpContext.Current.Request
>>  End Get
>>End Property
>>

If my premise is correct then No - except to remove the setting of the references in the BeginRequest()
