LocationHeaderFilter

For a response that generates a redirect to the proxied application, this filter rewrites the Location header on the response to redirect the user to IG.

Usage

{
    "name": string,
    "type": "LocationHeaderFilter",
    "config": {
        "baseURI": runtime expression<uri string>
    }
}

An alternative value for type is RedirectFilter.

Properties

"baseURI": runtime expression<uri string>, optional

The base URI of the IG instance. This is used to rewrite the Location header on the response.

The result of the expression must be a string that represents a valid URI, but is not a real java.net.URI object. For example, it would be incorrect to use ${request.uri}, which is not a String but a MutableUri.

Default: Redirect to the original URI specified in the request.

See also "Expressions".

Example

In the following example, IG listens on https://openig.example.com:443 and the application it protects listens on http://app.example.com:8081. The filter rewrites redirects that would normally take the user to locations under http://app.example.com:8081 to go instead to locations under https://openig.example.com:443.
