##### Type
|

|
||||
Content type is normally detected automatically, defaulting to
|

`text/gemini; charset=utf-8`. This option forces a specific content type.

Forward requests to [FastCGI](https://en.wikipedia.org/wiki/FastCGI) server at

A `Root` attribute must also be specified to use `FastCGI`.
