I have tried both 9.41.1.73 and 9.5.0.14 versions of the VC++ Chilkat libs with this. I'm using the code from the Chilkat example, http://www.example-code.com/vcpp/http_check_size.asp, to determine the size of a file prior to download.
That all works fine but I get a bunch of memory leaks on exit even though I'm calling CkSettings::cleanupMemory() on exit of the app. If I delete the CkHttpResponse pointer when I'm finished with it, there are no memory leaks. The example doesn't delete the pointer and the documentation doesn't indicate you need to delete it. Should it be deleted? If no, why the memory leaks?
Here is the list of leaks reported:

Object dump complete.
Yes. For any method that returns a new instance of a Chilkat object, that Chilkat object must be deleted by your application.
Ok, thanks. I don't see that specified in the example or documentation (unless I just missed it). Perhaps that would be a good thing to add.
