Version 1.4

Added parameter for configuring status code check.

The optional -a flag can now be used to specify which status codes are accepted
as good. The default remains the same as before.

See Readme for details.

Version 1.3

You can now use -s to customize the string that check_https uses to validate the response body data returned by the web server.

By default it will continue to use the same value that was previously hard-coded, <!DOCTYPE HTML>, so this will not change the default behaviour.

See Readme for details.

Version 1.2

Follow redirect now also follows 307s.

See Readme for details.

Version 1.1

Added configurable timeout. Default remains at 30, but you can now increase or decrease this.
