IHeader is a free Chrome add-on developed by Louis. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory.

With IHeader, users can monitor and modify the request and response headers of web pages. This tool allows users to add, delete, or edit the headers of any specified URL. Even after restarting the browser, the global listener remains effective.

IHeader is particularly useful for HTTP cache research, debugging HTTP interface fields, and providing temporary solutions for cross-origin issues during interface debugging. Many users have successfully debugged cross-origin interfaces using this tool. If your work involves tasks related to HTTP request and response headers, IHeader can simplify your workflow.
