HARview
About
HARview is a HAR (HTTP Archive) viewer. HAR is a JSON-encoded recording of HTTP requests, responses and timings. .har Files can be exported from Chrome's Developer Tools' "Network" tab by capturing some traffic, right-clicking in the results pane and selecting 'Save as HAR with content'.
HARView is a commandline tool which takes as input a .har (HTTP Archive) file and dumps a human-readable summary of it to the console. It is mostly useful for long dumps with many requests (such as debugging SAML / OAuth / etc). These can be captured in Chrome by enabling the "Preserve Log upon Navigation" button in the Network analyser.
