Generate HAR files for troubleshooting

When troubleshooting issues with an Applitools product, you may have someone request a HAR file so that they can understand what network requests are sent by your browser. 

What is a HAR file?

A HAR (HTTP Archive) file is a JSON-formatted file that records the network traffic between a web browser and a website. It captures detailed information about each request and response, including headers, body content, cookies, timing information, and other metadata. HAR files are commonly used for diagnosing performance issues, troubleshooting problems, and analyzing web application behavior.
