Analyzing HAR files

HAR is a quasi-standardized JSON format for saving HTTP traffic. It is supported by many HTTP-related tools, including developer consoles of some Web browsers.

HTTPolice can analyze HAR files with the -i har option:

$ httpolice -i har myfile.har

However, please note that HAR support in exporters is erratic. HTTPolice tries to do a reasonable job on files exported from major Web browsers and some other HTTP tools, but some information is lost and some checks are skipped to avoid false positives.

If HTTPolice gives unexpected results on your HAR files, feel free to submit an issue (don’t forget to attach the files), and I’ll see what can be done about it.
