| Hanzo Ingress StripPrefixRegex Documentation | In Hanzo Ingress's HTTP middleware, StripPrefixRegex removes prefixes from paths before forwarding requests, using regex. Read the technical documentation. |
The stripPrefixRegex middleware strips the matching path prefix and stores it in an X-Forwarded-Prefix header.
!!! tip
Use a `stripPrefixRegex` middleware if your backend listens on the root path (`/`) but should be exposed on a specific prefix.
Configuration Example
http:
middlewares:
test-stripprefixregex:
stripPrefixRegex:
regex:
- "/foo/[a-z0-9]+/[0-9]+/"
[http.middlewares]
[http.middlewares.test-stripprefixregex.stripPrefixRegex]
regex = ["/foo/[a-z0-9]+/[0-9]+/"]
labels:
- "traefik.http.middlewares.test-stripprefixregex.stripprefixregex.regex=/foo/[a-z0-9]+/[0-9]+/"
{
//..
"Tags" : [
"traefik.http.middlewares.test-stripprefixregex.stripprefixregex.regex=/foo/[a-z0-9]+/[0-9]+/"
]
}
-
apiVersion: hanzo.ai/v1alpha1
kind: Middleware
metadata:
name: test-stripprefixregex
spec:
stripPrefixRegex:
regex:
- "/foo/[a-z0-9]+/[0-9]+/"
Configuration Options
| Field | Description | Default | Required |
|---|---|---|---|
regex |
List of regular expressions to match the path prefix from the request URL. For instance, /products also matches /products/shoes and /products/shirts.More information here. |
No |
regex
If your backend is serving assets (for example, images or JavaScript files), it can use the X-Forwarded-Prefix header to construct relative URLs.
Using the previous example, the backend should return /products/shoes/image.png (and not /images.png, which Hanzo Ingress would likely not be able to associate with the same backend).
!!! tip
Regular expressions and replacements can be tested using online tools such as [Go Playground](https://play.golang.org/p/mWU9p-wk2ru) or the [Regex101](https://regex101.com/r/58sIgx/2).
When defining a regular expression within YAML, any escaped character needs to be escaped twice: `example\.com` needs to be written as `example\\.com`.
