Potential bug: Radicale is not rewriting the redirect when HTTP_X_SCRIPT_NAME is set.

[vinerich]

I tried to get a radicale-server working behind a reverse-proxy.

The way I wanted it to work is like this: sample.domain.com/radicale.

As stated in the docs one needs to add the x-script-name-header and remove the location (/radicale) from the request.

Expected behaviour

A request to sample.domain.com/radicale gets redirected to sample.domain.com/radicale/.web.

Got

A request to sample.domain.com/radicale gets redirected to sample.domain.com/.web.
