Regex Targeting
Apply headers to specific URLs using Regex
Regex Targeting
One of the most powerful features of Privacy Header is the ability to apply headers only when the URL matches a specific pattern.
How it Works
When adding a header, you can specify a Regex pattern. The extension checks the URL of every outgoing request against this pattern.
- If the URL matches, the header is modified.
- If the URL does not match, the header is left unchanged.
Examples
Match a specific domain
To apply headers only to example.com:
^https?:\/\/(www\.)?example\.com\/.*Match all subdomains
To apply headers to api.test.com, app.test.com, etc.:
^https?:\/\/.*\.test\.com\/.*Match a specific path
To apply headers only to API requests:
.*\/api\/v1\/.*Match Everything (Default)
If you leave the regex field empty or use .*, the header will be applied to all requests.
