HTTP Archive (HAR) is a standardized format used to capture interactions between web browsers and websites. HAR files are valuable for diagnosing errors encountered by users or administrators. Below are instructions for generating HAR files using popular web browsers: Chrome, Firefox, Safari, and Edge.

Note: A HAR file contains various data, including cookies and downloaded pages recorded during the session. This data may include personal or sensitive information. It's important to handle HAR files securely since anyone with access can view this data. Consider using a HAR sanitizer to remove sensitive information before sharing the file.

Review our supported browsers to ensure a seamless experience.

Before you send a HAR file, it's essential to follow these steps to ensure smooth delivery:

1. Rename the HAR file: By default, HAR files use the page URL as their name. However, filenames with ".com" extensions might trigger spam or phishing filters. Rename the HAR file to something descriptive that excludes the full URL.
2. Compress the HAR file: HAR files can be large and uncompressed files may exceed attachment limits. To avoid issues, compress the HAR file into a ZIP or another compressed format.

Following these steps ensures that your HAR file is safely prepared for submission without encountering attachment size restrictions or triggering security filters.
