    Configuration Options

    The StripPrefixRegex middleware will:

    • strip the matching path prefix.
    • store the matching path prefix in a X-Forwarded-Prefix header.

    Tip

    Use a stripPrefixRegex middleware if your backend listens on the root path (/) but should be routeable on a specific prefix.

    Tip

    Regular expressions can be tested using online tools such as Go Playground or the .

    For instance, /products would match /products but also /products/shoes and /products/shirts.

    Since the path is stripped prior to forwarding, your backend is expected to listen on /.

    If your backend is serving assets (e.g., images or Javascript files), chances are it must return properly constructed relative URLs.

    The header can be queried to build such URLs dynamically.
