In your handler, you would do something like this to implement the latter:

    /* set a "Location:" header and 302 redirect. */

    /* assemble the url by appending the filename to a baseurl */
    uri =3D apr_pstrcat(r->pool, baseurl, filename, NULL);

    apr_table_setn(r->headers_out, "Location", uri);

    return HTTP_MOVED_TEMPORARILY;
