HTTF-801 — The proxy cannot convert FTP directory listing into an HTML page
If a request with scheme ftp: is sent to the proxy, it is handled in cooperation with ftp-proxy. This error message means that http-proxy received FTP directory listing from ftp-proxy, but it cannot convert it into a HTML document, because at least one line of the listing does not fit into the client connection data buffers. Set HTTP-PROXY.CLIENT-CONN.SEND-BUFSIZE to a larger value.
