Fix nginx ssi unsafe URI was detected error

If your FE project enabled SSI (Server Side Includes) plugin, you may get some errors or a lots:

[error] 1788#0: *149 unsafe URI “xxx” was detected while sending response to client

Normally, nginx support SSI syntax like

<!--# include virtual="include/foo.html"-->

But if your include path has some go up dir such as ../, then get our errors:

<!--# include virtual="../include/foo.html"-->

have a search NGINX source code, got the SSI related files

ngx_http_parse_unsafe_uri in src/http/ngx_http_parse.c

if (ngx_path_separator(ch) && len > 2) {

    /* detect "/../" and "/.." */

    if (p[0] == '.' && p[1] == '.'
            && (len == 3 || ngx_path_separator(p[2])))
    {
        goto unsafe;
    }
}

OK, for develop ENV test, we can fix this issues by comments these codes:

ngx_http_ssi_include in src/http/modules/ngx_http_ssi_filter_module.c

/*
if (ngx_http_parse_unsafe_uri(r, uri, &args, &flags) != NGX_OK) {
    return NGX_HTTP_SSI_ERROR;
}
*/
