HTTP Archive 1.2 support

[ahmadnassri]

passing a HAR Request 1.2 in options.har will construct and set matching options values for use in the request.

this makes the library particularly useful when dealing with debug / performance data from many tools and proxies, especially to repeat requests from the browser's network panel.

Thanks @ahmadnassri ! Without being very familiar with HAR (or at all), I can say that your code looks great. 👍 from me for merging this PR.

The next request release is scheduled for the upcoming week, so in the meantime I'll review your code again more thoroughly, just to familiarize myself with HAR.

Same here, thank you for contributing :)

@simov I left some notes but I probably won't have time to do a more detailed code review.

thanks for the notes @nylen, new commit coming right up.

@simov you've inspired me to create this up-to-date collection of resources for HTTP Archive :)

[simov]

That's a really comprehensive list @ahmadnassri 👍 I'll merge your PR shortly, in case anyone else have something to add. btw you have one more broken anchor where you link back to the HAR section from the options.

I've added Request to the list of HAR Resources

cheers.
