What is an HAR file?
The .HAR (HTTP Archive) file extension is used for files that store HTTP session data in a standardized JSON format. These files are typically used to track and analyze network traffic between a web browser and a server. They can capture various details about HTTP requests and responses, including headers, body content, and timing information.
More Information.
The HTTP Archive format was initially proposed to help developers understand and improve the performance of web pages by recording and analyzing network interactions. It provides a comprehensive record of all network requests and responses, including timings and payloads, which can be invaluable for performance testing and troubleshooting.
Origin Of This File.
The .HAR format was introduced by the W3C Web Performance Working Group as part of the HTTP Archive format specification. It was designed to facilitate the exchange and analysis of network performance data, making it easier for developers to debug and optimize web applications.
File Structure Technical Specification.
The .HAR file format is based on JSON and includes the following key sections:
- log: The root object, which contains metadata and entries for the recorded data.
- version: The HAR version number.
- creator: Information about the tool that created the HAR file.
- pages: An array of page objects, each representing a web page.
- entries: An array of request/response entries, detailing individual HTTP transactions.
