intercept page http requests and provide custom http responses

[devonsams]

When making a request for a screenshot, I wanted the ability to pass along any data the page may request. This way I can avoid the round trip to any rest apis the page may be calling and provide the data directly from Browserless. Let me know what you think about this.

This looks great, and thanks for the tests as well! I’m curious about your thoughts on when using this API, versus something like the function API? Reason I ask is that it’s probably easier to grok what’s going on in the function API versus having to read implementation details here for newcomers.

Overall this looks a great, and I might apply it to the two other APIs that share a similar interface!

I definitely like having the function API as a fallback option. It's nice, however, to be able to provide a clean API that the rest of the infrastructure on my end can interact with directly, without having to introduce or modify another a service to act as a middle layer. I understand wanting to keep the functionality here free of bloat though, and if that's the strategy, I guess it's just a matter of deciding where to draw the line.

Thanks for approving this though! Sorry for missing those console.logs.
