Use new EiffelNet routines that do not raise exception on error.
Made compilable with 16.05 and dev-and-upcoming release 16.11.
Fixed various minor issues related to base_url, and added comments.
- the standalone connector support for SSL, is using certicate files for now (no in-memory support).
- to enable ssl support, set ecf variable `httpd_ssl_enabled=true`.
- added the `simple_ssl` example to demonstrate how to have standalone ssl server.
(be careful when using EiffelNet SSL and the http_client library, disable the libcurl
via ecf variable `libcurl_http_client_disabled=true` )
Added support for recv timeout to the EiffelWeb standalone connector.
- made EiffelWeb compilable with 16.05 and upcoming 16.11.
Done via ecfs condition on version to accept EiffelNet with recv_timeout (from 16.11), and without (until 16.05).
- adding recv timeout prevents server to hang for ever if a client wait too long to send data.
Updated various comments.
