What is a HAR file?\u00a0<\/strong><\/h4>

HAR stands for HTTP Archive and is a container for lots of trace information from within a browser. It records all web requests made by the browser tab, including the request & response headers, the body and the time it looks to load. This makes HAR files very useful when troubleshooting issues relating to speed, caching and issues which are harder to replicate.<\/p>

Security warning:<\/strong>
A HAR file captures all information a user submits via a web page while network traffic is being recorded. This can include passwords, payment information, and private keys.\u00a0Be cautious when generating a HAR file that includes this information, and never send a HAR file with sensitive information over email.<\/strong>\u00a0 You can manually remove all sensitive information using a text editor.<\/p>
