Trying to write an HTTP fuzzer

Wasnt't sure if there was a forum to post questions, so I figured I'd ask here. As the title says, I'm trying to write an HTTP fuzzer for practice, but right now I'm kind of stuck at how to link things together. I'm writing an HTTPFeedback that holds a set of HTTP codes, and the idea is that in its `is_interesting` function, it will see if the HTTP status code is in its set, and return a value based on that. The only problem is, how do I communicate the returned HTTP status code to the feedback? Would I do that through the ExitKind or state or something else?

Thanks if you're able to help out, and if this isn't the right place to ask, I'd be more than happy to repost my question somewhere else.
