  - ### resultProcessing

    protected HTTPSampleResult resultProcessing(boolean areFollowingRedirect, int frameDepth, HTTPSampleResult res)
    Follow redirects and download page resources if appropriate. this works, but the container stuff here is what's doing it. followRedirects() is actually doing the work to make sure we have only one container to make this work more naturally, I think this method - sample() - needs to take an HTTPSamplerResult container parameter instead of a boolean:areFollowingRedirect.

    Invokes `HTTPSamplerBase.resultProcessing(boolean, int, HTTPSampleResult)`

    Parameters:
