Generating a HAR File

Introduction

Selligent is an application that runs in the browser. When troubleshooting issues, it is sometimes necessary for our Support team to obtain more details about the network requests that are generated in your browser while an issue occurs.

A Selligent team member may request you to record a HAR file, a log of network requests, while the issue is occurring allowing them further investigation and analysis.

Note: Be aware that HAR files can contain sensitive data, including content of the pages that are downloaded and cookies that are set while recording.

This potentially allows anyone with the HAR file to impersonate your account and all the information that you have submitted while recording (personal details, passwords, credit card numbers, etc.).

 

What is a HAR file?

HAR (HTTP Archive Format) is a file that stores session data over many browsers (IE, Firefox, Chrome, Safari, …) between client and server. HAR contains HTTP response and request headers in the network environment when communication between the sender and receiver occurs, during the recording time window.

HAR files are used to inspect what is happening behind the scenes of your browser. More specifically, it contains all the details about operations performed by your browser during the recording time window. It includes information such as requests made, response times, response status codes, payloads, etc.

These files may contain sensitive or personal data! Make sure to store these files securely and share your HAR files created while using Selligent, with Selligent employees only.

At Selligent by Zeta, we are compromised to store the data that you send to us in a secure way. If desired, please check our Privacy Policy to learn more about how we handle and process client data.

 

Instructions

When you want to create a HAR file, it is important to start recording before the issue occurs. When a problem has already occurred, usually it is too late to record a HAR file.

In that case, try and see if you can reproduce the issue that had just occurred. Start recording and follow the reproduction steps and export your HAR file, as this method will ensure the file will contain as little noise and unnecessary data as possible.
