Capturing HTTP Headers on Google Chrome


Capturing HTTP Headers on Google Chrome

At times, Zscaler Support might ask you to provide HTTP headers when troubleshooting certain issues. The HTTP headers identify the specific URL the browser accessed when you opened a web page. Google Chrome has a built-in developer tool that allows you to capture HTTP headers and save them to a file. You can use the Google Chrome embedded HTTP header capture tool on Google Chrome version 54.0.2840.71 m. If you are running a different browser version, the steps might be different.
