October 10th, 2009 - 9:00AM We’ve been working with Jan Odvarko, from the Firebug team to create an open file format for sharing HTTP log files. It uses text based, JSON encoding and has been designed for ease of use over performance or comprehensiveness. Most popular programming languages have libraries that can handle the parsing or creation of JSON files so it should be relatively easy to extract data from or create HTTP ARchive (HAR) files.
We released HttpWatch version 6.2 today and one of its major new features is import:

and export of HAR files:

There’s no automation support and you can’t save a HAR file as a native HttpWatch log file in this version, but that will be added in a future update to HttpWatch.
To export files from the Net Panel Firebug you’ll need:
There’s also a HAR viewer that renders the file in your browser. At the moment, only Firebug and HttpWatch officially support this file format but other tools vendors are expected to add support in the near future.
The current version of the HAR file format is not as comprehensive as the native HttpWatch file format, so it is still worth saving your log files initially in the .hwl file format. You can then create HAR files if required in HttpWatch Studio.
HttpWatch version 6.2 also contains these new features:
A detailed list of changes and fixes in this release is available on the version history page .
