Why IInternetProtocol::Read didn`t retrieve all content in PassthruAPP?   

I managed to intercept IInternetProtocol::Read calls to record the
HTTP response body with the PassthruAPP toolkit.But sometimes
IInternetProtocol::Read didn`t read all content.It always occurs when
the response was cached(with Winxp sp IE7).Why and how to record the
whole content?

Thanks.

I've never had any such problems. Most likely, you are doing something 
wrong. If you can make a small sample reproducing the problem, email it 
to me at itandetnik@mvps.org, I'll look at it.

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925

Hi Igor,

Thanks for your reply.

I was just noticed that IInternetProtocolRoot::Abort was called once
after IInternetProtocol::Read was called in this situation.I guess it
may be caused by IE optimization mechanism:When the cache file of the
request is avalible,IE may read data from internet temporary file and
abord the binding operation.Dose this mean I should read file reported
by BINDSTATUS_CACHEFILENAMEAVAILABLE instead of hooking
IInternetProtocol::Read ?

Thanks

I've never seen this behavior either.
