ModHeader tutorial

Here is a short tutorial to help you get started with ModHeader. This tutorial should take 1-2 minutes to complete.

Step 1: Add a header

  • To get started with ModHeader, click on the ModHeader icon in the browser extension area.
  • If this is your first time using ModHeader, you should already see an empty row under Request headers. If not, click on , and select Request header to add an empty row.
  • Enter hello as a request header name, and world as a request header value.
  • It appears that the hello request header value is not added. Try changing the value in ModHeader and try again. Review this step again if needed.

Step 2: Add a filter

  • The request header we added is being sent to all HTTP requests. This may not be desirable as we may leak sensitive data to third party websites.
  • To reduce the risk, let's add a URL filter by clicking on , and select URL filter.
  • You should see a new row being added under URL filters. The value should be .*://modheader.com/.*. This means that our custom header will be added only to HTTP requests to modheader.com. It will not be sent to other domains.
  • It appears that the hello request header value is not added. Double check your filters.
