HAR format

The HTTP Archive format, or HAR, is a JSON-formatted archive file format for logging of a web browser’s interaction with a site. The common extension for these files is .har


Awesome. Google Chrome allows you to export a session of network traffic as an HAR, as do a number of others. Nice. If you’re scraping a website and want to capture the requests that help construct that page e.g. a single page JS application that makes 10 calls to a JSON API. Automate this and you’ve got quite an arsenal, you can part scrape a page’s content, grab urls of all images loaded, pinch cookies, etc all from the HAR.

Tell me more, how do I construct my own????

The specification for this format is produced by the Web Performance Working Group1 of the World Wide Web Consortium (W3C). This document was never published by the W3C Web Performance Working Group and has been abandoned

Handy. Thanks.

This might help :S
